IMHO these type of projects are not tools per-se but methodologies. I think this is a better framing since that's exactly what they are - a bunch of markdown files that describe in general terms how to perform an assessment aligned to some principles.
Btw, these type of methodologies are used all the time. Practically every security consultancy has them so adding them to an LLM makes a lot of sense.
All these security/vulnerability scanning harnesses look more or less the same. Not sure what’s the point of bragging or publishing about them anymore, there’s no moat
Vulnhunter isn't that exciting but if you scroll down their feed you'll see "guide to common rust errors" which... also isn't very exciting. I think they just need to publish something every week.
fwiw I have seen good whitepapers from them. A while back I used one about their IVR to get exec buy in for re-doing my company's IVR into something a lot better.
Eh, Capital One has long been surprisingly progressive on open source and whatnot. They were one of the first to properly adopt OAuth to connect accounts, too, back when Plaid/Mint/etc. were mostly proxying logins.
I'm on the fence here, for one as from recent Linux mailing discussions those tools can really find good bugs (51% of them?), but on other side - I'm afraid of false sense of security.
Sorry to say, tokens aren’t going anywhere, people aren’t going to suddenly stop using AI, and this whole paradigm shift of how people are changing how they work - is a full blown reality.
There is no reversal, no “eh we don’t think the tokens/AI are worth it”. Accept the new reality.
It doesn’t take a genius or system architect to figure out AI use in banking both internally and for consumers is a huge benefit especially for capital one.
Maybe we should critique the actual agentic products they are creating rather than critique the entire AI spend.
Don’t underestimate how banks operate. Things move very slowly in banking, so they absolutely need to justify it. Many banks still use GPT Mini, and even that requires approval from two levels of management. Even upgrading from Java 8 to Java 17 requires extensive justification.
Forget AI—you even have to justify using a MacBook.
you can, but it's better to use a different model or higher effort level at the very least to do the verifying part. (haven't checked to see what it is they are doing exactly), but doing vulnerability validation with the same model and effort you used to find the vulnerabilities isn't going to be a true second set of eyes and the model will likely always just try and justify it was right in the first place. ime, it's better to start with a fresh, clean context and at the very least a higher effort level on the same model. pass the finding(s) to a model that hasn't seen it before and it will judge it with an unbiased perspective.
Curious if the team at CapitalOne can share in more detail how this tool is being used internally, including how it’s helped their security practices and culture. That would help address some of the legitimacy concerns.

Has anyone actually had success with this? I applied for my company several weeks ago, and never heard back.
Wasn't Capital One founded on the premise of massive-scale market and product experimentation? Makes sense that they would design tools that match that approach.

I imagine they built it mostly for themselves, but open sourcing it is a nice gesture.
An end product to justify the Billions spent on AI
Also so that the engineers have something for the resume that looks and sounds impressive.
They don't know that Dario told me Fable is going to hack the planet.
They're desperate for the hype.

If there is a pentester here who uses mitmproxy, the security skills below (distilled from 4000 h1 disclosures) might help -https://github.com/instavm/security-skills
this is just a side project though for me
There are few more:

Why does this feel like an exec trying to justify token spend?
They dont need to justify it.

We also have to stop treating any criticism of some practices surrounding AI adoption like a rejection of the technology.
True, but this post in about Capital One.

You’re correct, but in the span of time - they are just doing the same thing everyone else is doing in many industries, just way slower
I think it's actually interesting how you can use the same model to both find and falsify the findings
you can, but it's better to use a different model or higher effort level at the very least to do the verifying part.

Seems to be very random. I've heard stories like yours, as well as companies who applied and are approved same day.

This is a sad. Makes me want to move my bank accounts.
Why?
Put a wrapper around nessus, stave off a "below strong" rating another six months
I know a few companies that did this about 20 years back (cough Comodo). Charge customers for a free Nessus report that's been rebranded. Profit.
VulnHunter: Capital One’s open-source, agentic AI code security tool.
seems weird to not include shell scripts.
