If I understand Anthropic's statements correctly, they've been cranking for a while, and what they have now is the results of Mythos-enabled vulnerability scans on every important piece of software they could find. (I do want to acknowledge how crazy it is that "vulnerability scan all important software repos in the world" is even an operation that can be performed.)
We talked to Nicholas Carlini on SCW and did not at all get the impression that they've hit everything they can possibly hit. They're still proving the concept one target at a time, last I heard.
> Over the past few weeks, we have used Claude Mythos Preview to identify thousands of zero-day vulnerabilities (that is, flaws that were previously unknown to the software’s developers), many of them critical, in every major operating system and every major web browser, along with a range of other important pieces of software.
They don’t explicitly rule out, I suppose, that these were only limited partial scans they did to find the vulnerabilities. But I don’t know why they’d do it that way, it’s not like they don’t have the resources to scan the entire Linux kernel.
i was trying to map "vulnerability scan all important software repos in the world" to an actual quote on their writing, but "every major operating system and every major web browser, along with a range of other important pieces of software" is not the same.
Can't you? My understanding is that that's exactly how security scans usually work - you run an analysis, find all the vulnerabilities, and then the continuous process is only there to check against the introduction of new vulnerabilities. Is that not the right mental model?
(A "security scanner" is a one-and-done proposition because it's deterministic and is going to find what it finds the first time you run and nothing more. But a software security assessment project you run every year on the same target with different teams will turn up different stuff every year. I'm at pains to remind people how totally lame source code security scanners are. People keep saying "static analyzers already do this" and like, nobody in security takes those tools seriously.)
