The system card unfortunately only refers to this [0] blog post and doesn't go into any more detail. In the blog post Anthropic researchers claim: "So far, we've found and validated more than 500 high-severity vulnerabilities".
The three examples given include two Buffer Overflows which could very well be cherrypicked. It's hard to evaluate if these vulns are actually "hard to find". I'd be interested to see the full list of CVEs and CVSS ratings to actually get an idea how good these findings are.
Given the bogus claims [1] around GenAI and security, we should be very skeptical around these news.

I know some of the people involved here, and the general chatter around LLM-guided vulnerability discovery, and I am not at all skeptical about this.

It does if the person making the statement has a track record, proven expertise on the topic - and in this case… it actually may mean something to other people
Yes, as we all know that unsourced unsubstantiated statements are the best way to verify claims regarding engineering practices. Especially when said person has a financial stake in the outcomes of said claims.
No conflict of interest here at all!
I have zero financial stake in Anthropic and more broadly my career is more threatened by LLM-assisted vulnerability research (something I do not personally do serious work on) than it is aided by it, but I understand that the first principal component of casual skepticism on HN is "must be a conflict of interest".

You still haven't answered why I should care that you, a stranger on the internet, believes some unsubstantiated hearsay?

The user you're suspicious of is pretty well-known in this community.
Someone's credibility cannot be determined by their point counts. Holy fuck is that not a way to evaluate someone in the slightest. Points don't matter.
Instead look at their profile...
Points != creds. Creds == creds.
Don't be fucking lazy and rely on points, especially when they link their identity.
