In short, a Wikimedia Foundation account was doing some sort of test which involved loading a large number of user scripts. They decided to just start loading random user scripts, instead of creating some just for this test.
The user who ran this test is a Staff Security Engineer at WMF, and naturally they decided to do this test under their highly-privileged Wikimedia Foundation staff account, which has permissions to edit the global CSS and JS that runs on every page.
One of those random scripts was a 2 year old malicious script from ruwiki. This script injects itself in the global Javascript on every page, and then in the userscripts of any user that runs into it, so it started spreading and doing damage really fast. This triggered tons of alerts, until the decision was made to turn the Wiki read-only.
It's either a a Career Limiting Event, or a Career Learning event.
In the case of a Learning event, you keep your job, and take the time to make the environment more resilient to this kind of issue.
In the case of a Limiting event, you lose your job, and get hired somewhere else for significantly better pay, and make the new environment more resilient to this kind of issue.
I've only just heard of it. But, I already knew to not run random scripts under a privileged account. And thank you for the book suggestion - I'm into those kinds of tales.
Or just restore from backup across the board. Assuming they do their backups well this shouldn't be too hard (especially since its currently in Read Only mode which means no new updates)
Are you sure?
Are you $150 million ARR sure?
Are you $150 million ARR, you'd really like to keep your job, you're not going to accidentally leave a hole or blow up something else, sure?
I agree, mostly, but I'm also really glad I don't have to put out this fire. Cheering them on from the sidelines, though!
Once you get big enough… there comes a point where you need to run some code and learn what happens when 100 million people hitting it at once looks like. At that scale, “1 in a million class bugs/race conditions” literally happen every day. You can’t do that on every PR, so you ship it and prepare to roll back if anything even starts to look fishy. Maybe even just roll it out gradually.
At least, that’s how it worked at literally every big company I worked at so far. The only reason to hold it back is during testing/review. Once enough humans look at it, you release and watch metrics like a hawk.
And yeah, many features were released this way, often gated behind feature flags to control roll out. When I refactored our email system that sent over a billion notifications a month, it was nerve wracking. You can’t unsend an email and it would likely be hundreds of millions sent before we noticed a problem at scale.
> One of those random scripts was a 2 year old malicious script from ruwiki. This script injects itself in the global Javascript on every page, and then in the userscripts of any user that runs into it, so it started spreading and doing damage really fast.
It's a mediawiki feature: there's a set of pages that get treated as JS/CSS and shown for either all users or specifically you. You do need to be an admin to edit the ones that get shown to all users.
Yes, you can have your own JS/CSS that’s injected in every page. This is pretty useful for widgets, editing tools, or to customize the website’s apparence.
For the global ones that need admin permissions to edit, it's no different from all the other code of mediawiki itself like the php.
For the user scripts, it's no worse than the fact that you can run tampermonkey in your browser and have it modify every page from evry site in whatever way your want.
It is kind of risky - you now have an entire, mostly unreviewed, ecosystem of javascript code, that users can experiment with.
However its been really useful to allow power users to customize the interface to their needs. It also is sort of a pressure release for when official devs are too slow for meeting needs. At this point wikipedia has become very dependent on it.
Wow. This worm is fascinating. It seems to do the following:
- Inject itself into the MediaWiki:Common.js page to persist globally, and into the User:Common.js page to do the same as a fallback
- Uses jQuery to hide UI elements that would reveal the infection
- Vandalizes 20 random articles with a 5000px wide image and another XSS script from basemetrika.ru
- If an admin is infected, it will use the Special:Nuke page to delete 3 random articles from the global namespace, AND use the Special:Random with action=delete to delete another 20 random articles
EDIT! The Special:Nuke is really weird. It gets a default list of articles to nuke from the search field, which could be any group of articles, and rubber-stamps nuking them. It does this three times in a row.
As someone on the Wikipediocracy forums pointed out, basemetrika.ru does not exist. I get an NXDomain response trying to resolve it. The plot thickens.
I registered it about 40 minutes ago, but it seems the DNS has been cached by everyone as a result of the wikipedia hack & not even the NS is propagating. Can't get an SSL certificate .
I had looked into its availability too just out of curiosity itself before reading your comment on a provider, Then I read your comment. Atleast its taken in from the hackernews community and not a malicious actor.
Do keep us updated on the whole situation if any relevant situation can happen from your POV perhaps.
I'd suggest to give the domain to wikipedia team as they might know what could be the best use case of it if possible.
Not quite sure which channels I should reach out via but I've put my email on the page so they can contact me.
Based on timings, it seems that Wikipedia wasn't really at risk from the domain being bought as everything was resolved before NS records could propagate. I got 1 hit from the URL which would've loaded up the script and nothing since.
Pretty sure it is, however, the reverse is actually illegal (for US citizens to provide professional services to anyone residing in Russia) as of like 2022-ish
reg.ru, the most popular registrar, sells .ru domains for $1.65, very little of which goes to the national registry. What is their profit on this domain, a couple of cents?
You have helped to bring peace by approximately zero nanoseconds, while doing absolutely nothing about western countries still buying massive amounts of natural resources from Putin. Tax income on their exports make the primary source of income for the federal budget, which directly funds the military.
Good virtue signaling, though. I'm completely disillusioned with the West, this is nothing new.
I don't think voting with your wallet constitutes virtue signaling, especially at a time when end user boycotting is one of the universally known methods of protest.
I am a pragmatist so maybe I will never understand this line of thinking. But in my mind, there are no perfect options, including doing nothing.
By doing nothing, you are allowing a malicious actor to buy the domain. In fact I am sure they would love for everyone else to be paralyzed by purity tests for a $1 domain.
All things being equal, yeah don’t buy a .ru domain. But they are not equal.
> Vandalizes 20 random articles with a 5000px wide image and another XSS script from basemetrika.ru
Note while this looks like its trying to trigger an xss, what its doing is ineffective, so basemetrika.ru would never get loaded (even ignoring that the domain doesnt exist)
I wouldn't be surprised either. But the original formatting of the worm makes me think it was human written, or maybe AI assisted, but not 100% AI. It has a lot of unusual stylistic choices that I don't believe an AI would intentionally output.
I would. AI designed software in general does not include novel ideas. And this is the kind of novel software AI is not great at, because there's not much training data.
Of course it's very possible someone wrote it with AI help. But almost no chance it was designed by AI.
> Cleaning this up is going to be an absolute forensic nightmare for the Wikimedia team since the database history itself is the active distribution vector.
Well, worm didn't get root -- so if wikimedia snapshots or made a recent backup, probably not so much of a nightmare? Then the diffs can tell a fairly detailed forensic story, including indicators of motive.
Snapshotting is a very low-overhead operation, so you can make them very frequently and then expire them after some time.
Even if they reset to several days ago and lose, say, thousands of edits, even tens of thousands of minor edits, they're still in a pretty good place. Losing a few days of edits is less-than-ideal but very tolerable for Wikipedia as a whole
At $work we're hosting business knowledge databases. Interestingly enough, if you need to revert a day or two of edits, you're better off to do it asap, over postponing and mulling over it. Especially if you can keep a dump or an export around.
People usually remember what they changed yesterday and have uploaded files and such still around. It's not great, but quite possible. Maybe you need to pull a few content articles out from the broken state if they ask. No huge deal.
If you decide to roll back after a week or so, editors get really annoyed, because now they are usually forced to backtrack and reconcile the state of the knowledge base, maybe you need a current and a rolled-back system, it may have regulatory implications and it's a huge pain in the neck.
Nah, you can snapshot every 15 minutes. The snapshot interval depends on the frequency of changes and their capacity, but it's up to them how to allocate these capacities... but it's definitely doable and there are real reasons for doing so. You can collapse deltas between snapshots after some time to make them last longer. I'd be surprised if they don't do that.
As an aside, snapshotting would have prevented a good deal of horror stories shared by people who give AI access to the FS. Well, as long as you don't give it root.......
obviously you can. but, what is the actual snapshot frequency? like, what is the timestamp of the last known good snapshot? that is what matters.
in any case, the comment you are replying to is a hypothetical, which correctly points out that even a day or two of lost edits is fine (not ideal, but fine). your reply doesnt engage with their comment at all.
> the comment you are replying to is a hypothetical, which correctly points out that even a day or two of lost edits is fine (not ideal, but fine). your reply doesnt engage with their comment at all.
I did engage, by pointing out that it wasn't relevant nor a realistic scenario for a competent sysadmin. (Did you read the OP?) That's a /you/ problem if you rely on infrequent backups, especially for a service with so much flux.
> what is the actual snapshot frequency? like, what is the timestamp of the last known good snapshot?
? Why would I know what their internal operations are?
>I did engage, by pointing out that it wasn't relevant nor a realistic scenario for a competent sysadmin.
>Why would I know what their internal operations are?
i mean... you must, right? you know that once-a-day snapshots is not relevant to this specific incident. you know that their sysadmins are apparently competent. i just assumed you must have some sort of insider information to be so confident.
> my decade of dealing with incompetent sysadmins and broken backups (if they even exist) has given me the opposite of confidence.
Oh, I agree that the average bar is low. That's part of the reason I do it all myself.
The heuristic with wikimedia is that they've been running a PHP service that accepts and stores (anonymous) input for 25 years. The longetivity with the risk exposure that they have are indicators that they know what they are doing, and I'm sure they've learned from recovering all sorts of failures over the years.
Look at how quickly it was brought back up in this instance!
So, yeah. I don't think initial hypothetical counterpoint holds water, and that's what I have been pointing out.
I have good faith, though I should get off hn now... :P
I still don't need to assume what the intent is. Troll or no troll, it works. My comments might inspire someone else to try a CoW fs. I'm also really impressed with wikimedia's technical team.
i found kibone's reply to a hypothetical musing as if it was some counterpoint in a debate instead of a simple expansion on their comment to be off putting. we had some comments back and forth and we both came out of it just fine. weird of you to add on this little insult to an otherwise pretty normal exchange.
Nowadays I refuse to do any serious work that isn't in source control anywhere besides my NAS that takes copy-on-write snapshots every 15 minutes. It has saved my butt more times than I can count.
The problem isn't the granularity of the backup but since the worm silently nukes pages, it's virtually impossible to reconcile the state before the attack and the current state, so you have to just forfeit any changes made since then and ask the contributors to do the leg work of reapplying the correct changes
No: from what I can tell, they're being conservative, which is appropriate here. Once you've pushed the "stop bad things happening" button, there's no need to rush.
A theory on phab: "Some investigation was made in Russian Wikipedia discord chat, maybe it will be useful.
1. In 2023, vandal attacks was made against two Russian-language alternative wiki projects, Wikireality and Cyclopedia. Here https://wikireality.ru/wiki/РАОрг is an article about organisators of these attacks.
I remember someone mass-defacing the ruwiki almost exactly a year ago (March 3 2025) with some immature insults towards certain ruwiki admins. If I'm not mistaken it was a similar method.
- There are constant deface incidents caused by editing of unprotected / semiprotected templates
- There were incidents of UI mistranslation (because MediaWiki translation is crowdsourced)
- The attack that was applied is well know in Russian community, it is pretty much standard "admin-woodpecker". The standard woodpecker (some people call it neo-woodpecker) renamed all pages with a high speed (I know this since 2007, the name woodpecker appeared many years later); then MediaWiki added throttling for renames; then neo-woodpecker reappeared in different years (usually associated with throttling bypass CVEs). Early admin-woodpeckers were much more destructive (destroyed a dozens of mediawiki websites due to lack of backups). Nuking admin woodpecker it quite a boring one, but I think (I hope) there are some AbuseFilter guardrails configured to prevent complex woodpeckers.
- The attack initiator is 100% a well known user; there are not too many users who applied woodpecker in the first place; not too many "upyachka" fans (which indicates that user edited before 2010 - back then active editors knew each other much better). But it is quite pointless to discuss who exactly the initiator is.
- Wikireality page is hijacked by a small group and does not represent the reality.
Also, I’m also surprised an XSS attack like hasn’t yet been actually used to harvest credentials like passwords through browser autofill[0].
It seems like the worm code/the replicated code only really attacks stuff on site. But leaking credentials (and obviously people reuse passwords across sites) could be sooo much worse.
I think autofill-based credential harvesting is harder than it sounds because browsers and password managers treat saved credentials as a separate trust boundary, and every vendor implements different heuristics. The tricky part is getting autofill to fire without a real user gesture and then exfiltrating values, since many browsers require exact form attributes or a user activation and several managers ignore synthetic events.
If an attacker wanted passwords en masse they could inject fake login forms and try to simulate focus and typing, but that chain is brittle across browsers, easy to detect and far lower yield than stealing session tokens or planting persistent XSS. Defenders should assume autofill will be targeted and raise the bar with HttpOnly cookies, SameSite=strict where practical, multifactor auth, strict Content Security Policy plus Subresource Integrity, and client side detection that reports unexpected DOM mutations.
"The incident appears to have been a cross-site scripting hack. The origin of rhe malicious scripts was a userpage on the Russian Wikipedia. The script contained Russian language text.
During the shutdown, users monitoring [https://meta.wikimedia.org/wiki/special:RecentChanges Recent changes page on Meta] could view WMF operators manually reverting what appeared to be a worm propagated in common.js
Hopefully this means they won't have to do a database rollback, i.e. no lost edits. "
Interesting to note how trivial it is today to fake something as coming "from the Russians".
Why do you think it was faked? It is a well known Russian tech (woodpecker), the earliest version I can find now was created in 2013 (but I personally saw it in 2007), it is a well known Russian damocles sword against misconfigured MediaWiki websites.
The Wikipedia community takes a cavalier attitude towards security. Any user with "interface administrator" status can change global JavaScript or CSS for all users on a given Wiki with no review. They added mandatory 2FA only a few years ago...
Prior to this, any admin had that ability until it was taken away due to English Wikipedia admins reverting Wikimedia changes to site presentation (Mediaviewer).
But that's not all. Most "power users" and admins install "user scripts", which are unsandboxed JavaScript/CSS gadgets that can completely change the operation of the site. Those user scripts are often maintained by long abandoned user accounts with no 2 factor authentication.
Based on the fact user scripts are globally disabled now I'm guessing this was a vector.
The Wikimedia foundation knows this is a security nightmare. I've certainly complained about this when I was an editor.
But most editors that use the website are not professional developers and view attempts to lock down scripting as a power grab by the Wikimedia Foundation.
> Any user with "interface administrator" status can change global JavaScript or CSS for all users on a given Wiki with no review.
True, but there aren't very many interface administrators. It looks like there are only 137 right now [0], which I agree is probably more than there should be, but that's still a relatively small number compared to the total number of active users. But there are lots of bots/duplicates in that list too, so the real number is likely quite a bit smaller. Plus, most of the users in that list are employed by Wikimedia, which presumably means that they're fairly well vetted.
Those are the English Wikipedia-only users, but you also need to include the "global" users (which I think were the source of this specific compromise?). Search this page [0] for "editsitejs" to see the lists of global users with this permission.
The worm is a two year old script from the Russian Wiki that was grabbed randomly for a test by a stupid admin running unsandboxed with full privileges, so no.
> Based on the fact user scripts are globally disabled now I'm guessing this was a vector.
Disabled at which level?
Browsers still allow for user scripts via tools like TamperMonkey and GreaseMonkey, and that's not enforceable (and arguably, not even trivially visible) to sites, including Wikipedia.
As I say that out loud, I figure there's a separate ecosystem of Wikipedia-specific user scripts, but arguably the same problem exists.
session compromise at this scale is usually less about breaking auth and more about harvesting valid sessions from environments where the browser itself leaks state. most "secure" sessions assume the browser is a neutral transport - but the browser exposes a surprising amount of identity through fingerprint consistency across tabs, timing patterns, and cached state that survives logout. the interesting question here isn't the auth model, it's what the attacker's client looked like at the time of the requests.
It is true that they have a particularly robust, distributed backup system that can/has come in handy, but FWIW the timing matters to them. English Wikipedia receives ~2 edits per second, or 172,800 per day. Many of them are surely minor and/or automated, but still: 1,036,800 lost edits is a lot!
In fact, as long as the malware is just doing deletes, you can just merge the two "timelines" by restoring the snapshot and then replaying all the edits but ignoring the deletes. Lost deletes really aren't much of a problem!
Filesystem & database snapshots are very cheap to make, you can make them every 15 minutes. You can expire old snapshots (or collapse the deltas between them) depending on the storage requirements.
That doesn't really matter though against an attack that takes some time to spread. If the attack was active for let's say, 6 hours, then 43,000 legitimate edits happened in between the last "clean" snapshot and the discovery of the attack. If you just revert to the last clean snapshot you lose those legitimate edits.
I completely understand marking the software that controls drinking water as critical infrastructure- but at some point a state based cyber attack that just wipes wikipedia off the net is deeply damaging to our modern society’s ability to agree on common facts …
Just now thought “if Wikipedia vanished what would it mean … and it’s not on the level of safe drinking water, but it is a level.
That someone would need to restore some backups, and in the meantime, use mirrors.
Seriously, not that big of a deal. I don't know how many copies of Wikipedia are lying around but considering that archives are free to download, I guess a lot. And if you count text-only versions of the English Wikipedia without history and talk pages, it is literally everywhere as it is a common dataset for natural language processing tasks. It is likely to be the most resilient piece of data of that scale in existence today.
The only difficulty in the worst case scenario would be rebuilding a new central location and restarting the machinery with trusted admins, editors, etc... Any of the tech giants could probably make a Wikipedia replacement in days, with all data restored, but it won't be Wikipedia.
What you're suggesting is literally impossible. There are plenty of mirrors and random people that download the thing in its entirety. The entire planet would have to be nuked for that to be possible.
The dump of english wikipedia is 26gb compressed and completely usable with that compressed format plus a small index file.
That's small enough to live on most people's phones. It's small enough to be a single BluRay. Maybe Wikipedia should fund some mass printings.
What you do not get however is any media. No sounds, images, videos, drawings, examples, 3D artifacts, etc etc etc. This is a huge loss on many many many topics.
There are so many mirrors anyway and trivial to get a local copy? What is much more concerning is government censorship and age verification/digital id laws where what articles you read becomes part of your government record the police sees when they pull you over.
> but at some point a state based cyber attack that just wipes wikipedia off the net is deeply damaging to our modern society’s ability to agree on common facts
Haven't we hit that point already with bad faith (and potentially government-run) coordinated editing and voting campaigns, as both Wales and Sanger have been pointing out for a while now?
I'm not sure what you mean by this. Wikipedia is not a democracy.
> as both Wales and Sanger have been pointing out
{{fv}}. Neither of those essays make this point. The closest either gets is Sanger's first thesis, which misunderstands the "support / oppose" mechanism. Ironically, his ninth thesis says to introduce voting, which would create the "voting campaign" vulnerability!
These are both really bad takes, which I struggle to believe are made in good faith, and I'm glad Wikipedians are mostly ignoring them. (I have not read the third link you provided, because Substack.)
Not the GP, and I don't believe in the existence of "common facts" in general, but Wikipedia is indeed a good place to figure out what other people might agree as common facts...
Well, I'm not sure either what the term "common facts" is supposed to mean, but wikipedia is not a good place to look for what "other people" think, unless if by "other people" you mean a small set of wikipedia powerusers. Just like traditional newspapers are controlled by a small set of editors who decide what's worth publishing, so is wikipedia.
I've never understood why client-side execution is so heavy in modern web pages. Theoretically, the costs to execute it are marginal, but in practice, if I'm browsing a web page from a battery-powered device, all that compute power draining the battery not only affects how long I can use the device between charges, but is also adding wear to the battery, so I'll have to replace it sooner. Also, a lot of web pages are downright slow, because my phone can only perform 10s of billions of operations per second, which isn't enough to responsively arrange text and images (which are composited by dedicated hardware acceleration) through all of the client-side bloat on many modern web pages. If there was that much bloat on the server side, the web server would run out of resources with even moderate usage.
There's also a lot of client-side authentication, even with financial transactions, e.g. with iOS and Android locally verifying a users password, or worse yet a PIN or biographic information, then sending approval to the server. Granted, authentication of any kind is optional for credit card transactions in the US, so all the rest is security theater, but if it did matter, it would be the worst way to do it.
We should be using federated organizational architectures when appropriate.
For Wikipedia, consider a central read-only aggregated mirror that delegates the editorial function to specialized communities. Common, suggested tooling (software and processes) could be maintained centrally but each community might be improved with more independence. This separation of concerns may be a better fit for knowledge collection and archival.
Note: I edited to stress central mirroring of static content with delegation of editorial function to contributing organizations. I'm expressly not endorsing technical "dynamic" federation approaches.
In the early 2010’s I worked for a company whose primary income was subscriptions to site protection services - one of which included cleaning up malware-infected Wordpress installations. I worked on the team that did this job.
This exact type of database-stored executable javascript was one of the most annoying types of infections to clean up.
Ok, so there are tons of mediawiki installations all over the internet. What do these operators do? Set their wikis to read-only mode, hang tight, and wait for a security patch?
There is nothing to do, the incident was not caused by a vulnerability in mediawiki.
Basically someone who had permissions to alter site js, accidentally added malicious js. The main solution is to be very careful about giving user accounts permission to edit js.
[There are of course other hardening things that maybe should be done based on lessons learned]
There are already tools and techniques to validate served JS is as-intended, and these techniques could be beefed up by adding browser checks. I've been surprised these haven't been widely adopted given the spate of recent JS-poisoning attacks.
Well, admins (or anybody other than the developers / deployment pipeline) having permissions to alter the JS sounds like a significant vulnerability. Maybe it wasn't in the early 2000s, but unencrypted HTTP was also normal then.
That's a fair point, but keep in mind normal admin is not sufficient. For local users (the account in question wasn't local) you need to be an "interface admin", of which there are only 15 on english wikipedia.
The account in question had "staff" rights which gave him basically all rights on all wikis.
> Well, admins (or anybody other than the developers / deployment pipeline) having permissions to alter the JS sounds like a significant vulnerability.
It's a common feature of CMS'es and "tag management systems." Its presence is a massive PITA to developers even _besides_ the security, but PMs _love them_, in my experience.
And they probably used mind-control to make the admin run random userscripts on his privileged account as well, the capabilities of russian hackers is scary.
This is unfortunate that Wikipedia is under attack. It seems as if there are more malicious actors now than, say, 5 years ago.
This may be unrelated but I also noticed more attacks on e. g. libgen, Anna's archive and what not. I am not at all saying this is similar to Wikipedia as such, mind you, but it really seems as if there are more actors active now who target people's freedom now (e. g. freedom of choice of access to any kind of information; age restriction aka age "verification" taps into this too).
Wikipedia is not under attack. Some stupid admin running with full privileges unsandboxed ran a test that grabbed and ran random user scripts, and one of them just happened to be this 2 year old malicious script.
Interesting angle. Everyone has already pointed out that there are backups basically everywhere, and from an information standpoint, shaving off a day (or whatever) of edits just to get to a known-good point is effectively zero cost. But I wonder what the cost is of the potentially bad data getting baked into those models, and if anyone really cares enough to scrap it.
Another reason to make the default disabling JS on all websites, and the website should offer a service without JS, especially those implemented in obsolete garbage tech. If it's not an XSS from a famous website, it will be an exploit from a sketchy website.
Too much app logic in the client side (Javascript) has always been an attack vector. The more that can reasonably be server side, the more that can't be seen.
The amount of javascript is really beside the point here. The problem is that privileged users can easily edit the code without strong 2FA, allowing automatic propagation.
If they required 2FA every time you wanted to modify JS then it couldn't propagate automatically. Just requiring 2FA when you first log in wouldn't help, of course.
It's not, application logic exposed on the client side is always an attack vector for figuring out how it works and how attack vectors could be devised.
It's simply a calculated risk.
How much business and application logic you put in your Javascript is critical.
On your second unrelated comment about Wikipedia needing to use 2FA, there's probably a better way to do it and I hope mediawiki can do it.
I don't know what you mean by application logic being exposed client-side. To change the content on the website, nuke articles, and propagate the malicious JS code you need to hijack privileged users' credentials and use them to trigger server-side actions.
It doesn't matter how much functionality the JS was originally responsible for, it could've been as little as updating a clock, validating forms, or just some silly animation. Once that JS executes in your browser it has access to your cookies and local storage, which means it can trigger whichever server-side actions it wants.
My second comment is not unrelated. The root cause of this mess is the fact that JS can be edited by privileged users without an approval process. If every change to the JS code required the user to enter their 2FA code (TOTP, let's say) then there would be no way for the worm to spread whenever users visited a page.
> Hitting MediaWiki:Common.js is the absolute nightmare scenario for MediaWiki deployments because that script gets executed by literally every single visitor
...except for us security wonks who have js turned off by default, don't enable it without good reason, disable it ASAP, and take a dim view of websites that require it.
Not too many years ago this behavior was the domain of Luddites and schizophrenics. Today it has become a useful tool in the toolbox of reasonable self-defense for anybody with UID 0.
Perhaps the WMF should re-evaluate just how specialsnowflake they think their UI is and see if, maybe just maybe, they can get by without js. Just a thought.
It warms my heart that there's basically a 0% chance that they ever approach this camp's viewpoint based on the Herculean effort it took to switch over to a slightly more modern frontend a few years back. I'm glad you don't think of yourself of a Luddite, but I think you're vastly overstating how open people are to a purely-static web.
Also, FWIW: Wikipedia is "specialsnowflake". If it isn't, that's merely because it was so specialsnowflake that there's now a healthy of ecosystem of sites that copied their features! It's far, far more capable than a simple blog, especially when you get into editing it.
Ok, fair point. I presumed that this crowd would be far more familiar with the capabilities of HTML5 and dynamic pages sans js than most. (Surely more familiar than I, who only dabble in code by comparison.)
No, I'm not suggesting we all go back to purely-static web pages, imagemap gifs and server side navigation. But you're going to have a hard time convincing me that I really truly need to execute code of unknown provenance in my this-app-does-everything-for-me process just to display a few pages of text and 5 jpegs.
And for the record, I've called myself a Technologist for almost 30 years now. If I were a closet Luddite I'd be one of the greatest hypocrites of human history. :-)
Correct. Not sure about a sql archive, but the kiwix ZIM archive of the top 1M English articles including (downsized but not minimized) images is 43GiB: https://download.kiwix.org/zim/wikipedia/
And the entire English wikipedia with no images is, interestingly, also 43GiB.
Who wins the most from a Wikipedia outage and has questionable moral views?
The same who currently struggles to find paying customers for his services.
> edit: lol downvoted with no counterpoint, is it hitting a nerve?
I have upvoted ya fwiw and I don't understand it either why people would try to downvote ya.
I mean, if websites work for you while disabling js and you are fine with it. Then I mean JS is an threat vector somewhat.
Many of us are unable to live our lives without JS. I used to use librewolf and complete and total privacy started feeling a little too uncomfortable
Now I am on zen-browser fwiw which I do think has some improvements over stock firefox in terms of privacy but I can't say this for sure but I mainly use zen because it looks really good and I just love zen.
> I mean, if websites work for you while disabling js and you are fine with it. Then I mean JS is an threat vector somewhat
It's also been torture, I definitely don't prescribe it. :P Like you say, it's a sanity / utility / security tradeoff. I just happen to be willing to trade off sanity for utility and security.
And yes, unfortunately I have to enable JS for some sites -- the default is to leave it disabled. And of course with cloudflare I have to whitelist it specifically for their domains (well, the non analytics domains). But thankfully wikipedia is light and spiffy without the javascript.
I appreciate librewolf but when I used to use it, IIRC its fingerprinting features were too strict for some websites IIRC and you definitely have to tone it down a bit by going into the settings. Canvases don't work and there were some other features too.
That being said, Once again, Librewolf is amazing software. I can see myself using it again but I just find zen easier in the sense of something which I can recommend plus ubO obv
Personally these are more aesthetic changes more than anything. I just really like how zen looks and feels.
The answer is sort of, Just personal preference that's all.

Well done.

People getting up and running without any opportunity to be taught about security concerns (even those as simple as the risks of inadequate input verification), especially considering the infamous inconsistency in PHP's APIs which can lead to significant foot-guns, is both a blessing and a curse… Essentially a pre-cursor to some of the crap that is starting to be published now via vibe-coding with little understanding.
PHP is a fine language. It started my career. That said, it has a lot of baggage that can let you shoot yourself in the foot. Modern PHP is pretty awesome though.
Yeah of course PHP isn't the only programming language you can write bugs in. I don't think you can make it impossible to shoot yourself in the foot, but PHP gives you more opportunities than some other languages, especially with older PHP standard library functions.
One thing I particularly hate is when functions require calling another function afterwards to get any errors that happened, like `json_decode`. C has that problem too.
Problems don't make it a _bad_ programming language. All languages have problems. PHP just has more than some other languages.
Yeah. It's funny how companies don't like to hire people that use tools correctly, but insist on creating tools that allow them to hire cheaper, less-qualified people.
PHP works fine, if you're a halfway decent programmer. Same with C++.
Try not to take criticisms of tools personally. Phillips head screws are shit for a great many applications, while simultaneously being involved in billions of dollars of economic activity, and being a driver that everyone has available.
Yep, that's the sad truth - a language popularity often has nothing to do with it's security properties. People will happily keep churning out insecure junk as long as it makes them millions, botnet and data compromises be damned.
I can't edit nor be bothered to reply to all of the negative responses so I'll put it here.
Pretty much all of you missed the larger point. PHP was what allowed me to not work in retail forever, buy a forever house, never have to worry about losing my job (this may change in the future with AI) or being at risk for redundancy, having chosen to only work for small, "normal" well run profitable businesses.
Unless you're building a hyper scale product, it does the job perfectly. PHP itself is not a security issue; using it poorly is, and any language can be used poorly. PHP is still perfectly suitable for web dev, especially in 2026.
I've not used PHP in anger in well over a decade, but if the general environment out there is anything like it was back then there are likely a lot of people, mostly on cheap shared hosting arrangements, running PHP versions older than that and for the most part knowing no better.
That isn't the fault of the language of course, but a valid reason for some of the “ick” reaction some get when it is mentioned.
They have no incentive to improve the site, because they’re a for-profit entity.
Despite the constant screeching for donations, the entire site is owned by a company with shareholders. All the “donations” go to them. They already met their funding needs for the next century a long time ago, this is all profit.
That's a serious accusation. Can you elaborate? What is the name of the company? Why does the Wikimedia Foundation claim ownership? And if you're referring to the Wikimedia Foundation, then what do you mean by "shareholders"?
Yeah, but the purpose of an encyclopedia like Wikipedia (a tertiary source) is to relatively neutrally summarize the consensus of those who spend the time and effort to analyze and interpret the primary sources (and thus produce secondary sources), or if necessary to cite other tertiary summaries of those.
In a discussion forum like HN, pointing to primary sources is the most reliable input to the other readers' research on/synthesis of their own secondary interpretation of what may be going on. Pointing to other secondary interpretations/analyses is also useful, but not without including the primary source so that others can - with apologies to the phrase currently misused by the US right wing - truly do their own research.
If you spend any time on Wikipedia, you'll find that secondary sources from an existing list are always preferred. The mandate from the link in GP (https://en.wikipedia.org/wiki/Wikipedia:No_original_research) extends, or at least is interpreted to mean to extend to, actively punishing editors who attempt to analyze or interpret primary sources.
I live happily in the knowledge that in 20000 years when that eventually drifts off into another system and is picked up by aliens that they will reverse engineer it and wonder why the fuck '5'-'4'=1
I mean sure, but that's never going to happen, so complaining about it is just shaking your fist at the sky. The only way it will change is if the economics of the web change. Maybe that is the economics of developer time (it being easier/fast/more resilient and thus cheaper to do native dev), or maybe it is that dynamic scripting leads to such extreme vulnerabilities that ease of deployment/development/consumer usage change the macroeconomics of web deployment enough to shift the scales to local.
But if there's one thing I've learned over the years as a technologist, it's this: the "best technology" is not often the "technology that wins".
Engineering is not done in a vacuum. Indeed, my personal definition of engineering is that it is "constraint-based applied science". Yes, some of those constraints are "VC buxx" wanting to see a return on investment, but even the OSS world has its own set of constraints - often overlapping. Time, labor, existing infrastructure, domain knowledge.
The entire web is built on geopolitical stability and cooperation. That is no longer certain. We already have supply chains failing (RAM/storage) meaning that we will be hardware constrained for the foreseeable future. That puts the onus on efficiency and web apps are NOT efficient however we deliver them.
People are also now very concerned about data sovereignty whereas they previously were not. If it's not in your hands or on your computer than it is at risk.
The VC / SaaS / cloud industry is about to get hit very very hard via this and regulation. At that point, it's back to native as delivery is not about being tied to a network control point.
I've been around long enough to see the centralisation and decentralisation cycles. We're heading the other way now
Why? Well mostly due to the unpredictable behaviour of the country which seems to have the control points of most infra these days.
How? Well the numerous non-US sovereign technology initiatives are going to be incentivised through regulation with local compliance being the only option going forwards.
As a non-US person I am already speaking to people at other orgs in similar space as ours who are looking at options there.
Imagine if wikipedia was a native app, what this vuln would have caused. I for one prefer using stuff in the browser where at least it's sandboxed. Also, there's nothing stopping you from disabling JS in your browser.
See the public phab ticket: https://phabricator.wikimedia.org/T419143
In short, a Wikimedia Foundation account was doing some sort of test which involved loading a large number of user scripts. They decided to just start loading random user scripts, instead of creating some just for this test.
The user who ran this test is a Staff Security Engineer at WMF, and naturally they decided to do this test under their highly-privileged Wikimedia Foundation staff account, which has permissions to edit the global CSS and JS that runs on every page.
One of those random scripts was a 2 year old malicious script from ruwiki. This script injects itself in the global Javascript on every page, and then in the userscripts of any user that runs into it, so it started spreading and doing damage really fast. This triggered tons of alerts, until the decision was made to turn the Wiki read-only.
This is a pretty egregious failure for a staff security engineer
Pretty much the definition of a “career limiting event”
It's either a a Career Limiting Event, or a Career Learning event.
In the case of a Learning event, you keep your job, and take the time to make the environment more resilient to this kind of issue.
In the case of a Limiting event, you lose your job, and get hired somewhere else for significantly better pay, and make the new environment more resilient to this kind of issue.
Hopefully the Wikimedia foundation is the former.
Nobody is going to know who did this, so probably not career limiting in any major way.
They named him in the support ticket linked here somewhere.
> sbassett
They'll be fine, recruiters don't look this stuff up and generally background checks only care about illegal shit.
Didn't realise this was some historic evil script and not some active attacker who could change tack at any moment.
That makes the fix pretty easy. Write a regex to detect the evil script, and revert every page to a historic version without the script.
Letting ancient evil code run? Have we learned nothing from A Fire Upon the Deep?!
"It was really just humans playing with an old library. It should be safe, using their own automation, clean and benign.

Or just restore from backup across the board. Assuming they do their backups well this shouldn't be too hard (especially since its currently in Read Only mode which means no new updates)
Are you sure? Are you $150 million ARR sure? Are you $150 million ARR, you'd really like to keep your job, you're not going to accidentally leave a hole or blow up something else, sure?
I agree, mostly, but I'm also really glad I don't have to put out this fire. Cheering them on from the sidelines, though!
True but it does say something that such a script was able to lie dormant for so long.
Why would anyone test in production???!!!
There are plenty of ways to safely test in production. For one thing you need to limit the scope of your changes.
Selecting the wrong environment in your test setup by mistake?
I refuse to believe that someone on the security team intentionally tested random user scripts in production on purpose.
Once you get big enough… there comes a point where you need to run some code and learn what happens when 100 million people hitting it at once looks like. At that scale, “1 in a million class bugs/race conditions” literally happen every day. You can’t do that on every PR, so you ship it and prepare to roll back if anything even starts to look fishy. Maybe even just roll it out gradually.
At least, that’s how it worked at literally every big company I worked at so far. The only reason to hold it back is during testing/review. Once enough humans look at it, you release and watch metrics like a hawk.
And yeah, many features were released this way, often gated behind feature flags to control roll out. When I refactored our email system that sent over a billion notifications a month, it was nerve wracking. You can’t unsend an email and it would likely be hundreds of millions sent before we noticed a problem at scale.

It's a mediawiki feature: there's a set of pages that get treated as JS/CSS and shown for either all users or specifically you. You do need to be an admin to edit the ones that get shown to all users.
https://www.mediawiki.org/wiki/Manual:Interface/JavaScript
Yes, you can have your own JS/CSS that’s injected in every page. This is pretty useful for widgets, editing tools, or to customize the website’s apparence.
It sounds very dangerous to me but who am I to judge.
It's nothing.
For the global ones that need admin permissions to edit, it's no different from all the other code of mediawiki itself like the php.
For the user scripts, it's no worse than the fact that you can run tampermonkey in your browser and have it modify every page from evry site in whatever way your want.
It is kind of risky - you now have an entire, mostly unreviewed, ecosystem of javascript code, that users can experiment with.
However its been really useful to allow power users to customize the interface to their needs. It also is sort of a pressure release for when official devs are too slow for meeting needs. At this point wikipedia has become very dependent on it.
That is how Mediawiki works. Everything is a page, including CSS and JS. It is not really different than including JS in a webpage anywhere else.
On one hand, I was about to get irrationally angry someone was attacking Wikipedia, so I'm a bit relieved
On the other hand,
>a Staff Security Engineer at WMF, and naturally they decided to do this test under their highly-privileged Wikimedia Foundation staff account
seriously?
Wow. This worm is fascinating. It seems to do the following:
- Inject itself into the MediaWiki:Common.js page to persist globally, and into the User:Common.js page to do the same as a fallback
- Uses jQuery to hide UI elements that would reveal the infection
- Vandalizes 20 random articles with a 5000px wide image and another XSS script from basemetrika.ru
- If an admin is infected, it will use the Special:Nuke page to delete 3 random articles from the global namespace, AND use the Special:Random with action=delete to delete another 20 random articles
EDIT! The Special:Nuke is really weird. It gets a default list of articles to nuke from the search field, which could be any group of articles, and rubber-stamps nuking them. It does this three times in a row.
There doesn’t seem to be an ulterior motive beyond “Muahaha, see the trouble I can cause!”
A classical virus, from the good old days. None of this botnet/bitcoin mining in the background nonsense.
As someone on the Wikipediocracy forums pointed out, basemetrika.ru does not exist. I get an NXDomain response trying to resolve it. The plot thickens.
Yeah, basemetrika.ru is free now. Should we occupy it? ;)
I registered it about 40 minutes ago, but it seems the DNS has been cached by everyone as a result of the wikipedia hack & not even the NS is propagating. Can't get an SSL certificate .
nice work
I had looked into its availability too just out of curiosity itself before reading your comment on a provider, Then I read your comment. Atleast its taken in from the hackernews community and not a malicious actor.
Do keep us updated on the whole situation if any relevant situation can happen from your POV perhaps.
I'd suggest to give the domain to wikipedia team as they might know what could be the best use case of it if possible.
Not quite sure which channels I should reach out via but I've put my email on the page so they can contact me.
Based on timings, it seems that Wikipedia wasn't really at risk from the domain being bought as everything was resolved before NS records could propagate. I got 1 hit from the URL which would've loaded up the script and nothing since.
This community has no malicious actors? :)
I'm not malicious at least :)

Namecheap won’t sell it which is great because it made me pause and wonder whether it's legal for an American to send Russians money for a TLD.
Namecheap is Ukrainian, of course they won't sell you a .ru domain.
Is it? Wikipedia says:
> Namecheap is a U.S. based domain name registrar and web hosting service company headquartered in Phoenix, Arizona.
and in 2025 they were purchased by:
> CVC Capital Partners plc is a Jersey-based private equity and investment advisory firm
I remember that in 2022 a sizeable part of their workforce was located in Ukraine. Too lazy to search for proof, sorry!
Pretty sure it is, however, the reverse is actually illegal (for US citizens to provide professional services to anyone residing in Russia) as of like 2022-ish
I'm half-tempted to try and claim it myself for fun and profit, but I think I'll leave it for someone else.
What should we put there, anyway?
A JavaScript call to window.alert to pause the JavaScript VM.
Looks like someone other from the hackernews community has bought the domain https://news.ycombinator.com/item?id=47263323#47265499
Go old school and have the script inject the "how did this get here im not good with computers" cat onto random pages

Well done, it's finally over
reg.ru, the most popular registrar, sells .ru domains for $1.65, very little of which goes to the national registry. What is their profit on this domain, a couple of cents?
You have helped to bring peace by approximately zero nanoseconds, while doing absolutely nothing about western countries still buying massive amounts of natural resources from Putin. Tax income on their exports make the primary source of income for the federal budget, which directly funds the military.
Good virtue signaling, though. I'm completely disillusioned with the West, this is nothing new.
I don't think voting with your wallet constitutes virtue signaling, especially at a time when end user boycotting is one of the universally known methods of protest.
I am a pragmatist so maybe I will never understand this line of thinking. But in my mind, there are no perfect options, including doing nothing.
By doing nothing, you are allowing a malicious actor to buy the domain. In fact I am sure they would love for everyone else to be paralyzed by purity tests for a $1 domain.
All things being equal, yeah don’t buy a .ru domain. But they are not equal.
> Vandalizes 20 random articles with a 5000px wide image and another XSS script from basemetrika.ru
Note while this looks like its trying to trigger an xss, what its doing is ineffective, so basemetrika.ru would never get loaded (even ignoring that the domain doesnt exist)
Wouldn't be surprised if elaborate worms like this are AI-designed
I wouldn't be surprised either. But the original formatting of the worm makes me think it was human written, or maybe AI assisted, but not 100% AI. It has a lot of unusual stylistic choices that I don't believe an AI would intentionally output.
I would. AI designed software in general does not include novel ideas. And this is the kind of novel software AI is not great at, because there's not much training data.
Of course it's very possible someone wrote it with AI help. But almost no chance it was designed by AI.
I mean....elaborate is a stretch.
> Cleaning this up is going to be an absolute forensic nightmare for the Wikimedia team since the database history itself is the active distribution vector.
Well, worm didn't get root -- so if wikimedia snapshots or made a recent backup, probably not so much of a nightmare? Then the diffs can tell a fairly detailed forensic story, including indicators of motive.
Snapshotting is a very low-overhead operation, so you can make them very frequently and then expire them after some time.
Even if they reset to several days ago and lose, say, thousands of edits, even tens of thousands of minor edits, they're still in a pretty good place. Losing a few days of edits is less-than-ideal but very tolerable for Wikipedia as a whole
At $work we're hosting business knowledge databases. Interestingly enough, if you need to revert a day or two of edits, you're better off to do it asap, over postponing and mulling over it. Especially if you can keep a dump or an export around.
People usually remember what they changed yesterday and have uploaded files and such still around. It's not great, but quite possible. Maybe you need to pull a few content articles out from the broken state if they ask. No huge deal.
If you decide to roll back after a week or so, editors get really annoyed, because now they are usually forced to backtrack and reconcile the state of the knowledge base, maybe you need a current and a rolled-back system, it may have regulatory implications and it's a huge pain in the neck.
Nah, you can snapshot every 15 minutes. The snapshot interval depends on the frequency of changes and their capacity, but it's up to them how to allocate these capacities... but it's definitely doable and there are real reasons for doing so. You can collapse deltas between snapshots after some time to make them last longer. I'd be surprised if they don't do that.
As an aside, snapshotting would have prevented a good deal of horror stories shared by people who give AI access to the FS. Well, as long as you don't give it root.......
>Nah, you can snapshot every 15 minutes.
obviously you can. but, what is the actual snapshot frequency? like, what is the timestamp of the last known good snapshot? that is what matters.
in any case, the comment you are replying to is a hypothetical, which correctly points out that even a day or two of lost edits is fine (not ideal, but fine). your reply doesnt engage with their comment at all.
> the comment you are replying to is a hypothetical, which correctly points out that even a day or two of lost edits is fine (not ideal, but fine). your reply doesnt engage with their comment at all.
I did engage, by pointing out that it wasn't relevant nor a realistic scenario for a competent sysadmin. (Did you read the OP?) That's a /you/ problem if you rely on infrequent backups, especially for a service with so much flux.
> what is the actual snapshot frequency? like, what is the timestamp of the last known good snapshot?
? Why would I know what their internal operations are?
>I did engage, by pointing out that it wasn't relevant nor a realistic scenario for a competent sysadmin.
>Why would I know what their internal operations are?
i mean... you must, right? you know that once-a-day snapshots is not relevant to this specific incident. you know that their sysadmins are apparently competent. i just assumed you must have some sort of insider information to be so confident.
I think you are misreading my comments and made a bad assumption. The reason I'm confident is because this has been my bread and butter for a decade.
>The reason I'm confident is because this has been my bread and butter for a decade.
my decade of dealing with incompetent sysadmins and broken backups (if they even exist) has given me the opposite of confidence.
but im glad you have had a different experience
> my decade of dealing with incompetent sysadmins and broken backups (if they even exist) has given me the opposite of confidence.
Oh, I agree that the average bar is low. That's part of the reason I do it all myself.
The heuristic with wikimedia is that they've been running a PHP service that accepts and stores (anonymous) input for 25 years. The longetivity with the risk exposure that they have are indicators that they know what they are doing, and I'm sure they've learned from recovering all sorts of failures over the years.
Look at how quickly it was brought back up in this instance!
So, yeah. I don't think initial hypothetical counterpoint holds water, and that's what I have been pointing out.
Kudos for very polite responses to trolling.
I have good faith, though I should get off hn now... :P
I still don't need to assume what the intent is. Troll or no troll, it works. My comments might inspire someone else to try a CoW fs. I'm also really impressed with wikimedia's technical team.
no one is trolling in this comment chain.
i found kibone's reply to a hypothetical musing as if it was some counterpoint in a debate instead of a simple expansion on their comment to be off putting. we had some comments back and forth and we both came out of it just fine. weird of you to add on this little insult to an otherwise pretty normal exchange.
FWIW I did not assume that you were trolling, and yes we did come out fine.
Nowadays I refuse to do any serious work that isn't in source control anywhere besides my NAS that takes copy-on-write snapshots every 15 minutes. It has saved my butt more times than I can count.
Yeah same here. Earlier I had a sync error that corrupted my .git, somehow. no problem; I go back 15 minutes and copy the working version.
Feels good to pat oneself in the back. Mine is sore, though. My E&O/cyber insurance likes me.
The problem isn't the granularity of the backup but since the worm silently nukes pages, it's virtually impossible to reconcile the state before the attack and the current state, so you have to just forfeit any changes made since then and ask the contributors to do the leg work of reapplying the correct changes
Why would nuked pages matter? Snapshots capture everything and are not part of wikimedia software.
The nuke might be legitimate?
That's not a lot of state lost. Destructive operations are easier to replay than constructive ones.
Is Wikimedia overreacting then?
No: from what I can tell, they're being conservative, which is appropriate here. Once you've pushed the "stop bad things happening" button, there's no need to rush.
Nothing was rolled back in the db sense, i think people just used normal wiki revert tools.
It also never effected wikipedia, just the smaller meta site (used for interproject coordination)
A theory on phab: "Some investigation was made in Russian Wikipedia discord chat, maybe it will be useful.
1. In 2023, vandal attacks was made against two Russian-language alternative wiki projects, Wikireality and Cyclopedia. Here https://wikireality.ru/wiki/РАОрг is an article about organisators of these attacks.
2. In 2024, ruwiki user Ololoshka562 created a page https://ru.wikipedia.org/wiki/user:Ololoshka562/test.js containing script used in these attacks. It was inactive next 1.5 years.
3. Today, sbassett massively loaded other users' scripts into his global.js on meta, maybe for testing global API limits: https://meta.wikimedia.org/wiki/Special:Contributions/SBasse... . In one edit, he loaded Ololoshka's script: https://meta.wikimedia.org/w/index.php?diff=prev&oldid=30167... and run it."
I remember someone mass-defacing the ruwiki almost exactly a year ago (March 3 2025) with some immature insults towards certain ruwiki admins. If I'm not mistaken it was a similar method.
No, I think you are mixing something.
- There are constant deface incidents caused by editing of unprotected / semiprotected templates
- There were incidents of UI mistranslation (because MediaWiki translation is crowdsourced)
- The attack that was applied is well know in Russian community, it is pretty much standard "admin-woodpecker". The standard woodpecker (some people call it neo-woodpecker) renamed all pages with a high speed (I know this since 2007, the name woodpecker appeared many years later); then MediaWiki added throttling for renames; then neo-woodpecker reappeared in different years (usually associated with throttling bypass CVEs). Early admin-woodpeckers were much more destructive (destroyed a dozens of mediawiki websites due to lack of backups). Nuking admin woodpecker it quite a boring one, but I think (I hope) there are some AbuseFilter guardrails configured to prevent complex woodpeckers.
- The attack initiator is 100% a well known user; there are not too many users who applied woodpecker in the first place; not too many "upyachka" fans (which indicates that user edited before 2010 - back then active editors knew each other much better). But it is quite pointless to discuss who exactly the initiator is.
- Wikireality page is hijacked by a small group and does not represent the reality.
Woah this looks like an old school XSS worm https://meta.wikimedia.org/wiki/Special:RecentChanges?hidebo...
I’ve always thought the fact that MediaWiki sometimes lets editors embed JavaScript could be dangerous.
Also, I’m also surprised an XSS attack like hasn’t yet been actually used to harvest credentials like passwords through browser autofill[0].
It seems like the worm code/the replicated code only really attacks stuff on site. But leaking credentials (and obviously people reuse passwords across sites) could be sooo much worse.
[0] https://varun.ch/posts/autofill/
I think autofill-based credential harvesting is harder than it sounds because browsers and password managers treat saved credentials as a separate trust boundary, and every vendor implements different heuristics. The tricky part is getting autofill to fire without a real user gesture and then exfiltrating values, since many browsers require exact form attributes or a user activation and several managers ignore synthetic events.
If an attacker wanted passwords en masse they could inject fake login forms and try to simulate focus and typing, but that chain is brittle across browsers, easy to detect and far lower yield than stealing session tokens or planting persistent XSS. Defenders should assume autofill will be targeted and raise the bar with HttpOnly cookies, SameSite=strict where practical, multifactor auth, strict Content Security Policy plus Subresource Integrity, and client side detection that reports unexpected DOM mutations.
Chrome doesnt actually autofill before you interact. It only displays what it would fill in at the same location visually.
but any interaction is good for Chrome, like dismissing a cookie banner
Time to add 2FA...
A comment from my wiki-editor friend:
Interesting to note how trivial it is today to fake something as coming "from the Russians".Why do you think it was faked? It is a well known Russian tech (woodpecker), the earliest version I can find now was created in 2013 (but I personally saw it in 2007), it is a well known Russian damocles sword against misconfigured MediaWiki websites.

works for me
This was only a matter of time.
The Wikipedia community takes a cavalier attitude towards security. Any user with "interface administrator" status can change global JavaScript or CSS for all users on a given Wiki with no review. They added mandatory 2FA only a few years ago...
Prior to this, any admin had that ability until it was taken away due to English Wikipedia admins reverting Wikimedia changes to site presentation (Mediaviewer).
But that's not all. Most "power users" and admins install "user scripts", which are unsandboxed JavaScript/CSS gadgets that can completely change the operation of the site. Those user scripts are often maintained by long abandoned user accounts with no 2 factor authentication.
Based on the fact user scripts are globally disabled now I'm guessing this was a vector.
The Wikimedia foundation knows this is a security nightmare. I've certainly complained about this when I was an editor.
But most editors that use the website are not professional developers and view attempts to lock down scripting as a power grab by the Wikimedia Foundation.
Maybe somewhat unrelated, but I'm reminded of the fact that people have deleted the main page on a few occasions: https://en.wikipedia.org/wiki/Wikipedia:Don%27t_delete_the_m...
> Any user with "interface administrator" status can change global JavaScript or CSS for all users on a given Wiki with no review.
True, but there aren't very many interface administrators. It looks like there are only 137 right now [0], which I agree is probably more than there should be, but that's still a relatively small number compared to the total number of active users. But there are lots of bots/duplicates in that list too, so the real number is likely quite a bit smaller. Plus, most of the users in that list are employed by Wikimedia, which presumably means that they're fairly well vetted.

https://en.wikipedia.org/wiki/Special:ListUsers/interface-ad...
Those are the English Wikipedia-only users, but you also need to include the "global" users (which I think were the source of this specific compromise?). Search this page [0] for "editsitejs" to see the lists of global users with this permission.

Seems like a good time to donate one's resources to fix it. The internet is super hostile these days. If Wikipedia falls... well...
It's a political issue. Editors are unwilling or unable to contribute to development of the features they need to edit.
Unfortunately, Wikipedia is run on insecure user scripts created by volunteers that tend to be under the age of 18.
There might be more editors trying to resume boost if editing Wikipedia under your real name didn't invite endless harassment.
Wikipedia doesn't even spend donation of Wikipedia anymore.
Sounds more like a political issue this. Can't buy your way out of that.
My understanding is that Wikipedia receives more donations than they need, surely they have the resources to fix it themselves?
You would first need to realzie it's a problem.
Maybe this is the reason for this worm. Someone is angry because they don't got it in another way...
The worm is a two year old script from the Russian Wiki that was grabbed randomly for a test by a stupid admin running unsandboxed with full privileges, so no.
Browsers still allow for user scripts via tools like TamperMonkey and GreaseMonkey, and that's not enforceable (and arguably, not even trivially visible) to sites, including Wikipedia.
As I say that out loud, I figure there's a separate ecosystem of Wikipedia-specific user scripts, but arguably the same problem exists.
Yeah, wikipedia has its own user script system, and that was what was disabled.
The sitewide JavaScript/CSS is an editable Wiki page.
You can also upload scripts to be shared and executed by other users.
This is apparently not done browser side but server side.
As in, user can upload whatever they wish and it will be shown to them and ran, as JS, fully privileged and all.
For reference
>There are currently 15 interface administrators (including two bots).

session compromise at this scale is usually less about breaking auth and more about harvesting valid sessions from environments where the browser itself leaks state. most "secure" sessions assume the browser is a neutral transport - but the browser exposes a surprising amount of identity through fingerprint consistency across tabs, timing patterns, and cached state that survives logout. the interesting question here isn't the auth model, it's what the attacker's client looked like at the time of the requests.
Nice to see jQuery still getting used :)
>Cleaning this up
Find the first instance and reset to the backup before then. An hour, a day, a week? Doesn't matter that much in this case.
It is true that they have a particularly robust, distributed backup system that can/has come in handy, but FWIW the timing matters to them. English Wikipedia receives ~2 edits per second, or 172,800 per day. Many of them are surely minor and/or automated, but still: 1,036,800 lost edits is a lot!
Are they really lost though? I think they should not be lost; they could be stored in a separate database additionally.
In fact, as long as the malware is just doing deletes, you can just merge the two "timelines" by restoring the snapshot and then replaying all the edits but ignoring the deletes. Lost deletes really aren't much of a problem!
Filesystem & database snapshots are very cheap to make, you can make them every 15 minutes. You can expire old snapshots (or collapse the deltas between them) depending on the storage requirements.
That doesn't really matter though against an attack that takes some time to spread. If the attack was active for let's say, 6 hours, then 43,000 legitimate edits happened in between the last "clean" snapshot and the discovery of the attack. If you just revert to the last clean snapshot you lose those legitimate edits.
I completely understand marking the software that controls drinking water as critical infrastructure- but at some point a state based cyber attack that just wipes wikipedia off the net is deeply damaging to our modern society’s ability to agree on common facts …
Just now thought “if Wikipedia vanished what would it mean … and it’s not on the level of safe drinking water, but it is a level.
> if Wikipedia vanished what would it mean …
That someone would need to restore some backups, and in the meantime, use mirrors.
Seriously, not that big of a deal. I don't know how many copies of Wikipedia are lying around but considering that archives are free to download, I guess a lot. And if you count text-only versions of the English Wikipedia without history and talk pages, it is literally everywhere as it is a common dataset for natural language processing tasks. It is likely to be the most resilient piece of data of that scale in existence today.
The only difficulty in the worst case scenario would be rebuilding a new central location and restarting the machinery with trusted admins, editors, etc... Any of the tech giants could probably make a Wikipedia replacement in days, with all data restored, but it won't be Wikipedia.
What you're suggesting is literally impossible. There are plenty of mirrors and random people that download the thing in its entirety. The entire planet would have to be nuked for that to be possible.
Don't worry, I personally have an offline backup of the English on my phone.
You can download the entirety of wikipedia and store it in your own offline immutable backup.
The dump of english wikipedia is 26gb compressed and completely usable with that compressed format plus a small index file.
That's small enough to live on most people's phones. It's small enough to be a single BluRay. Maybe Wikipedia should fund some mass printings.
What you do not get however is any media. No sounds, images, videos, drawings, examples, 3D artifacts, etc etc etc. This is a huge loss on many many many topics.
All persistent data should have backup.
It's not a high bar.
There are so many mirrors anyway and trivial to get a local copy? What is much more concerning is government censorship and age verification/digital id laws where what articles you read becomes part of your government record the police sees when they pull you over.
> but at some point a state based cyber attack that just wipes wikipedia off the net is deeply damaging to our modern society’s ability to agree on common facts
Haven't we hit that point already with bad faith (and potentially government-run) coordinated editing and voting campaigns, as both Wales and Sanger have been pointing out for a while now?
See, for example,
* Sanger: https://en.wikipedia.org/wiki/User:Larry_Sanger/Nine_Theses
* Wales: https://en.wikipedia.org/wiki/Talk:Gaza_genocide/Archive_22#...
* PirateWires: https://www.piratewires.com/p/how-wikipedia-is-becoming-a-ma...
> Haven't we hit that point already with bad faith (and potentially government-run) coordinated editing […] campaigns,
Yes, this is a real phenomenon. See, for instance, https://en.wikipedia.org/wiki/Timeline_of_Wikipedia%E2%80%93...: the examples from 2006 are funny, and the article's subject matter just gets sadder and sadder as the chronology goes on.
> and voting campaigns
I'm not sure what you mean by this. Wikipedia is not a democracy.
> as both Wales and Sanger have been pointing out
{{fv}}. Neither of those essays make this point. The closest either gets is Sanger's first thesis, which misunderstands the "support / oppose" mechanism. Ironically, his ninth thesis says to introduce voting, which would create the "voting campaign" vulnerability!
These are both really bad takes, which I struggle to believe are made in good faith, and I'm glad Wikipedians are mostly ignoring them. (I have not read the third link you provided, because Substack.)
If you're using wikipedia to "agree on common facts" I think you might have bigger problems...
Not the GP, and I don't believe in the existence of "common facts" in general, but Wikipedia is indeed a good place to figure out what other people might agree as common facts...
Well, I'm not sure either what the term "common facts" is supposed to mean, but wikipedia is not a good place to look for what "other people" think, unless if by "other people" you mean a small set of wikipedia powerusers. Just like traditional newspapers are controlled by a small set of editors who decide what's worth publishing, so is wikipedia.
https://en.wikipedia.org/wiki/Wikipedia:What_Wikipedia_is_no...
https://grokipedia.com/
I just checked a wiki, and the "MediaWiki:Common.js" page there was read-only, even for wikisysop users.
You need to be a special type of admin, called "interface-admin" to edit it. Normal admin is not enough.
I've never understood why client-side execution is so heavy in modern web pages. Theoretically, the costs to execute it are marginal, but in practice, if I'm browsing a web page from a battery-powered device, all that compute power draining the battery not only affects how long I can use the device between charges, but is also adding wear to the battery, so I'll have to replace it sooner. Also, a lot of web pages are downright slow, because my phone can only perform 10s of billions of operations per second, which isn't enough to responsively arrange text and images (which are composited by dedicated hardware acceleration) through all of the client-side bloat on many modern web pages. If there was that much bloat on the server side, the web server would run out of resources with even moderate usage.
There's also a lot of client-side authentication, even with financial transactions, e.g. with iOS and Android locally verifying a users password, or worse yet a PIN or biographic information, then sending approval to the server. Granted, authentication of any kind is optional for credit card transactions in the US, so all the rest is security theater, but if it did matter, it would be the worst way to do it.
We should be using federated organizational architectures when appropriate.
For Wikipedia, consider a central read-only aggregated mirror that delegates the editorial function to specialized communities. Common, suggested tooling (software and processes) could be maintained centrally but each community might be improved with more independence. This separation of concerns may be a better fit for knowledge collection and archival.
Note: I edited to stress central mirroring of static content with delegation of editorial function to contributing organizations. I'm expressly not endorsing technical "dynamic" federation approaches.
Exactly. Wikipedia should be used on ipfs
In the early 2010’s I worked for a company whose primary income was subscriptions to site protection services - one of which included cleaning up malware-infected Wordpress installations. I worked on the team that did this job.
This exact type of database-stored executable javascript was one of the most annoying types of infections to clean up.
Ok, so there are tons of mediawiki installations all over the internet. What do these operators do? Set their wikis to read-only mode, hang tight, and wait for a security patch?
Also, does this worm have a name?
There is nothing to do, the incident was not caused by a vulnerability in mediawiki.
Basically someone who had permissions to alter site js, accidentally added malicious js. The main solution is to be very careful about giving user accounts permission to edit js.
[There are of course other hardening things that maybe should be done based on lessons learned]
There are already tools and techniques to validate served JS is as-intended, and these techniques could be beefed up by adding browser checks. I've been surprised these haven't been widely adopted given the spate of recent JS-poisoning attacks.
Well, admins (or anybody other than the developers / deployment pipeline) having permissions to alter the JS sounds like a significant vulnerability. Maybe it wasn't in the early 2000s, but unencrypted HTTP was also normal then.
That's a fair point, but keep in mind normal admin is not sufficient. For local users (the account in question wasn't local) you need to be an "interface admin", of which there are only 15 on english wikipedia.
The account in question had "staff" rights which gave him basically all rights on all wikis.
> Well, admins (or anybody other than the developers / deployment pipeline) having permissions to alter the JS sounds like a significant vulnerability.
It's a common feature of CMS'es and "tag management systems." Its presence is a massive PITA to developers even _besides_ the security, but PMs _love them_, in my experience.
I’m not saying that this is related to Wikipedia ditching archive.is but timing in combination with Russian messages is at least…weird.
The script was uploaded in 2024, and triggered today because of an accident
https://en.wikipedia.org/wiki/Wikipedia:Village_stocks#Scott...
And they probably used mind-control to make the admin run random userscripts on his privileged account as well, the capabilities of russian hackers is scary.
/s
It is just another human acting human again.
This is unfortunate that Wikipedia is under attack. It seems as if there are more malicious actors now than, say, 5 years ago.
This may be unrelated but I also noticed more attacks on e. g. libgen, Anna's archive and what not. I am not at all saying this is similar to Wikipedia as such, mind you, but it really seems as if there are more actors active now who target people's freedom now (e. g. freedom of choice of access to any kind of information; age restriction aka age "verification" taps into this too).
Wikipedia is not under attack. Some stupid admin running with full privileges unsandboxed ran a test that grabbed and ran random user scripts, and one of them just happened to be this 2 year old malicious script.
I wonder if any poisoned data made it into LLM training data pipelines?
Interesting angle. Everyone has already pointed out that there are backups basically everywhere, and from an information standpoint, shaving off a day (or whatever) of edits just to get to a known-good point is effectively zero cost. But I wonder what the cost is of the potentially bad data getting baked into those models, and if anyone really cares enough to scrap it.
Another reason to make the default disabling JS on all websites, and the website should offer a service without JS, especially those implemented in obsolete garbage tech. If it's not an XSS from a famous website, it will be an exploit from a sketchy website.
Too much app logic in the client side (Javascript) has always been an attack vector. The more that can reasonably be server side, the more that can't be seen.
The amount of javascript is really beside the point here. The problem is that privileged users can easily edit the code without strong 2FA, allowing automatic propagation.
How does 2FA prevent this here?
If they required 2FA every time you wanted to modify JS then it couldn't propagate automatically. Just requiring 2FA when you first log in wouldn't help, of course.
2FAs also may require a level of KYC that Wikipedia isn't after and advocating for 2FA might indirectly advocate for a lot more things than just 2FA.
KYC? I'm talking about standard 2FA methods like Time-based OTP codes.
It's not, application logic exposed on the client side is always an attack vector for figuring out how it works and how attack vectors could be devised.
It's simply a calculated risk.
How much business and application logic you put in your Javascript is critical.
On your second unrelated comment about Wikipedia needing to use 2FA, there's probably a better way to do it and I hope mediawiki can do it.
I don't know what you mean by application logic being exposed client-side. To change the content on the website, nuke articles, and propagate the malicious JS code you need to hijack privileged users' credentials and use them to trigger server-side actions.
It doesn't matter how much functionality the JS was originally responsible for, it could've been as little as updating a clock, validating forms, or just some silly animation. Once that JS executes in your browser it has access to your cookies and local storage, which means it can trigger whichever server-side actions it wants.
My second comment is not unrelated. The root cause of this mess is the fact that JS can be edited by privileged users without an approval process. If every change to the JS code required the user to enter their 2FA code (TOTP, let's say) then there would be no way for the worm to spread whenever users visited a page.
> Hitting MediaWiki:Common.js is the absolute nightmare scenario for MediaWiki deployments because that script gets executed by literally every single visitor
...except for us security wonks who have js turned off by default, don't enable it without good reason, disable it ASAP, and take a dim view of websites that require it.
Not too many years ago this behavior was the domain of Luddites and schizophrenics. Today it has become a useful tool in the toolbox of reasonable self-defense for anybody with UID 0.
Perhaps the WMF should re-evaluate just how specialsnowflake they think their UI is and see if, maybe just maybe, they can get by without js. Just a thought.
It warms my heart that there's basically a 0% chance that they ever approach this camp's viewpoint based on the Herculean effort it took to switch over to a slightly more modern frontend a few years back. I'm glad you don't think of yourself of a Luddite, but I think you're vastly overstating how open people are to a purely-static web.
Also, FWIW: Wikipedia is "specialsnowflake". If it isn't, that's merely because it was so specialsnowflake that there's now a healthy of ecosystem of sites that copied their features! It's far, far more capable than a simple blog, especially when you get into editing it.
Ok, fair point. I presumed that this crowd would be far more familiar with the capabilities of HTML5 and dynamic pages sans js than most. (Surely more familiar than I, who only dabble in code by comparison.)
No, I'm not suggesting we all go back to purely-static web pages, imagemap gifs and server side navigation. But you're going to have a hard time convincing me that I really truly need to execute code of unknown provenance in my this-app-does-everything-for-me process just to display a few pages of text and 5 jpegs.
And for the record, I've called myself a Technologist for almost 30 years now. If I were a closet Luddite I'd be one of the greatest hypocrites of human history. :-)
There's thousands of copies of the whole wikipedia in sql form though, IIRC it's just like 47GB.
Correct. Not sure about a sql archive, but the kiwix ZIM archive of the top 1M English articles including (downsized but not minimized) images is 43GiB: https://download.kiwix.org/zim/wikipedia/
And the entire English wikipedia with no images is, interestingly, also 43GiB.
Looking forward to the postmortem...
Just thought about.
Who wins the most from a Wikipedia outage and has questionable moral views? The same who currently struggles to find paying customers for his services.
The large AI companies.
GOD am I thankful to my old self for disabling js by default. And sticking with it.
edit: lol downvoted with no counterpoint, is it hitting a nerve?
> edit: lol downvoted with no counterpoint, is it hitting a nerve?
I have upvoted ya fwiw and I don't understand it either why people would try to downvote ya.
I mean, if websites work for you while disabling js and you are fine with it. Then I mean JS is an threat vector somewhat.
Many of us are unable to live our lives without JS. I used to use librewolf and complete and total privacy started feeling a little too uncomfortable
Now I am on zen-browser fwiw which I do think has some improvements over stock firefox in terms of privacy but I can't say this for sure but I mainly use zen because it looks really good and I just love zen.
> I mean, if websites work for you while disabling js and you are fine with it. Then I mean JS is an threat vector somewhat
It's also been torture, I definitely don't prescribe it. :P Like you say, it's a sanity / utility / security tradeoff. I just happen to be willing to trade off sanity for utility and security.
And yes, unfortunately I have to enable JS for some sites -- the default is to leave it disabled. And of course with cloudflare I have to whitelist it specifically for their domains (well, the non analytics domains). But thankfully wikipedia is light and spiffy without the javascript.
What is uncomfortable about Librewolf? I thought it was basically FF without telemetry and UBO already baked in?
I appreciate librewolf but when I used to use it, IIRC its fingerprinting features were too strict for some websites IIRC and you definitely have to tone it down a bit by going into the settings. Canvases don't work and there were some other features too.
That being said, Once again, Librewolf is amazing software. I can see myself using it again but I just find zen easier in the sense of something which I can recommend plus ubO obv
Personally these are more aesthetic changes more than anything. I just really like how zen looks and feels.
The answer is sort of, Just personal preference that's all.
I can edit it
"Закрываем проект" is Russian for "Closing the project"
It's reassuring to know Wikipedia has these kinds of security mechanisms in place.
Time to spend some of this excess money on a bit of security tightening? I hear we're talking about a 9 digit figure.
Here before someone says that it's because MediaWiki is written in PHP.
PHP is the language where "return flase" causes it to return true.
https://danielc7.medium.com/remote-code-execution-gaining-do...
Also the language that runs half of the web.
Also the language that has made me millions over my career with no degree.
Also the language that allows people to be up and running in seconds (with or without AI).
I could go on.
HN has taught me that any PL can embiggen its users’ ego. Not special in that regard.
> Also the language that has made me millions over my career with no degree.
Well done.
> Also the language that allows people to be up and running in seconds (with or without AI).
People getting up and running without any opportunity to be taught about security concerns (even those as simple as the risks of inadequate input verification), especially considering the infamous inconsistency in PHP's APIs which can lead to significant foot-guns, is both a blessing and a curse… Essentially a pre-cursor to some of the crap that is starting to be published now via vibe-coding with little understanding.
PHP is a fine language. It started my career. That said, it has a lot of baggage that can let you shoot yourself in the foot. Modern PHP is pretty awesome though.
Pretty sure we've seen people coding in essentially every other programming language also shoot themselves in the foot.
Every language has foot-guns of some sort. The difference is how easy it is to accidentally pull the trigger.
PHP makes it easy.
Yeah of course PHP isn't the only programming language you can write bugs in. I don't think you can make it impossible to shoot yourself in the foot, but PHP gives you more opportunities than some other languages, especially with older PHP standard library functions.
One thing I particularly hate is when functions require calling another function afterwards to get any errors that happened, like `json_decode`. C has that problem too.
Problems don't make it a _bad_ programming language. All languages have problems. PHP just has more than some other languages.
The language is not what makes you nor the product. You could've written the same thing in RoR, PHP was just first and it's why it still exists
PHP performance is significantly better than Ruby on Rails, which I think plays a part in its continued popularity.
Also the language that runs half of the web.
The bottom half.
;)
I use it on the backends of my stuff.
Works great, but, like any tool, usage matters.
People who use tools badly, get bad results.
I've always found the "Fishtank Graph" to be relevant: https://w3techs.com/technologies/history_overview/programmin...
People who use tools badly inflict bad results on other people, quite often far more so than they do so on themselves.
Yeah. It's funny how companies don't like to hire people that use tools correctly, but insist on creating tools that allow them to hire cheaper, less-qualified people.
PHP works fine, if you're a halfway decent programmer. Same with C++.
Try not to take criticisms of tools personally. Phillips head screws are shit for a great many applications, while simultaneously being involved in billions of dollars of economic activity, and being a driver that everyone has available.
Yep, that's the sad truth - a language popularity often has nothing to do with it's security properties. People will happily keep churning out insecure junk as long as it makes them millions, botnet and data compromises be damned.
PHP is insanely great, and very fast. The hate has no clout.
Perl still runs the other half?
I can't edit nor be bothered to reply to all of the negative responses so I'll put it here.
Pretty much all of you missed the larger point. PHP was what allowed me to not work in retail forever, buy a forever house, never have to worry about losing my job (this may change in the future with AI) or being at risk for redundancy, having chosen to only work for small, "normal" well run profitable businesses.
Unless you're building a hyper scale product, it does the job perfectly. PHP itself is not a security issue; using it poorly is, and any language can be used poorly. PHP is still perfectly suitable for web dev, especially in 2026.
FWIW this was fixed in 2020
I've not used PHP in anger in well over a decade, but if the general environment out there is anything like it was back then there are likely a lot of people, mostly on cheap shared hosting arrangements, running PHP versions older than that and for the most part knowing no better.
That isn't the fault of the language of course, but a valid reason for some of the “ick” reaction some get when it is mentioned.
PHP had its issues like every language, but also a minimal memory footprint, XML/SOAP parser, and several SQL database cursor options.
Most modern web languages like nodejs are far worse due to dependency rot, and poor REST design pattern implementations. =3
Except that in a contemporary PHP that doesn't work any more.
This means game over, the script stops there.They have no incentive to improve the site, because they’re a for-profit entity.
Despite the constant screeching for donations, the entire site is owned by a company with shareholders. All the “donations” go to them. They already met their funding needs for the next century a long time ago, this is all profit.
That's a serious accusation. Can you elaborate? What is the name of the company? Why does the Wikimedia Foundation claim ownership? And if you're referring to the Wikimedia Foundation, then what do you mean by "shareholders"?
How do they know? Has this been published in a Reliable Source?
This is the official Wikimedia Foundation status page for the whole of Wikipedia, so it's a reliable primary source.
Actually, usage of primary sources is kinda complicated [0], generally Wikipedia prefers secondary and tertiary sources.
[0] https://en.wikipedia.org/wiki/Wikipedia:No_original_research...
Yeah, but the purpose of an encyclopedia like Wikipedia (a tertiary source) is to relatively neutrally summarize the consensus of those who spend the time and effort to analyze and interpret the primary sources (and thus produce secondary sources), or if necessary to cite other tertiary summaries of those.
In a discussion forum like HN, pointing to primary sources is the most reliable input to the other readers' research on/synthesis of their own secondary interpretation of what may be going on. Pointing to other secondary interpretations/analyses is also useful, but not without including the primary source so that others can - with apologies to the phrase currently misused by the US right wing - truly do their own research.
If you spend any time on Wikipedia, you'll find that secondary sources from an existing list are always preferred. The mandate from the link in GP (https://en.wikipedia.org/wiki/Wikipedia:No_original_research) extends, or at least is interpreted to mean to extend to, actively punishing editors who attempt to analyze or interpret primary sources.
My original post was a joke about this.
Long past time to eliminate JavaScript from existence
You will have a long trek to do that. We have a javascript interpreter deployed at the second Sun-Earth Lagrange point.

I live happily in the knowledge that in 20000 years when that eventually drifts off into another system and is picked up by aliens that they will reverse engineer it and wonder why the fuck '5'-'4'=1
This.
Actually fuck the whole dynamic web. Just give us hypertext again and build native apps.
Edit: perhaps I shouldn't say this on an VC driven SaaS wankfest forum...
You may be interested in https://geminiprotocol.net/
Yes that's exactly what we should be using. Totally agree.
I mean sure, but that's never going to happen, so complaining about it is just shaking your fist at the sky. The only way it will change is if the economics of the web change. Maybe that is the economics of developer time (it being easier/fast/more resilient and thus cheaper to do native dev), or maybe it is that dynamic scripting leads to such extreme vulnerabilities that ease of deployment/development/consumer usage change the macroeconomics of web deployment enough to shift the scales to local.
But if there's one thing I've learned over the years as a technologist, it's this: the "best technology" is not often the "technology that wins".
Engineering is not done in a vacuum. Indeed, my personal definition of engineering is that it is "constraint-based applied science". Yes, some of those constraints are "VC buxx" wanting to see a return on investment, but even the OSS world has its own set of constraints - often overlapping. Time, labor, existing infrastructure, domain knowledge.
I think it will change.
The entire web is built on geopolitical stability and cooperation. That is no longer certain. We already have supply chains failing (RAM/storage) meaning that we will be hardware constrained for the foreseeable future. That puts the onus on efficiency and web apps are NOT efficient however we deliver them.
People are also now very concerned about data sovereignty whereas they previously were not. If it's not in your hands or on your computer than it is at risk.
The VC / SaaS / cloud industry is about to get hit very very hard via this and regulation. At that point, it's back to native as delivery is not about being tied to a network control point.
I've been around long enough to see the centralisation and decentralisation cycles. We're heading the other way now
I think on a high level we're in agreement then. All of those points you mentioned are constraints.
> "VC / SaaS / cloud industry is about to get hit very very hard via ... regulation"
can you explain?
Why? Well mostly due to the unpredictable behaviour of the country which seems to have the control points of most infra these days.
How? Well the numerous non-US sovereign technology initiatives are going to be incentivised through regulation with local compliance being the only option going forwards.
As a non-US person I am already speaking to people at other orgs in similar space as ours who are looking at options there.
Imagine if wikipedia was a native app, what this vuln would have caused. I for one prefer using stuff in the browser where at least it's sandboxed. Also, there's nothing stopping you from disabling JS in your browser.
Wikipedia should be straight hypermedia. Simple.
