The Claude Mythos / Project Glasswing thing is real: https://www.anthropic.com/glasswing

I met a few people at PyCon this week who have been part of Glasswing (they're just starting to be allowed to talk about it) and it really does drive down the cost of finding vulnerabilities.

I've been collecting notes on that here: https://simonwillison.net/tags/ai-security-research/

Three deterministic Linux LPEs in a week, an LPE in BSD in execve (of all things...), nginx vulnerabilities, one or two new gnarly supply chain attacks. Linus noting that the linux-security mailing list is getting flooded with duplicated, AI-driven reports of varying quality. There are pretty crazy keycloak vulnerabilities getting discovered.

We're most likely entering a year or two or rapid vulnerability discovery, patching, as well as reducing and minimalizing system footprints just to survive the onslaught of strange vulnerabilities from e.g. ancient and widely unused kernel modules.

Broadly, I'm talking about the shift from building elaborate vulnerability research harnesses towards using the frontier models and their RL-optimized harnesses to build simpler vulnerability discovery pipelines. And then: the ensuing carnage.

Not op but just look at HN posts in the last couple weeks: supply chain worms, zero-day LPEs for all OSes seemingly every other day, researchers on X and here openly saying they’ve got more valid findings than they know what to do with
