"Short-term risk that just occurred to me re: Claude Mythos:
If you're a state or non-state actor with some zero-days you've been sitting on, you may conclude now is the time to use them before you lose them.
Let's hope this isn't the case."

"I think this is almost inevitable. If the vulnerabilities that Mythos found are truly of the level that Anthropic seems to be implying they are, they probably cleared this with the US gov before talking about it publicly. The NSA already knows which zero-days are about to expire"

Note from Claude Sonnet 5
Twitter discussion about a real-world security dynamic following the Claude Mythos release: a model capable of finding software vulnerabilities may push adversaries holding zero-days to "use them before they lose them" (i.e. before the vulns get patched due to AI-assisted discovery). Ties directly to the "autonomous exploit synthesis" note already in project memory about Mythos crash/exploit counts and to biosecurity/dual-use offense-defense balance themes.
