I don't think that's true.
replyYou are up to date. Mythos had unauthorized access because of poor security but that's it as far as I know. Not exactly a good sign for something being advertised as a weapon...

replyIt’s easy to end up with no public-trusted third parties if we arbitrarily distrust third parties who say the capabilities match what’s promised. Mozilla for example says it found hundreds of Firefox vulnerabilities, and I think it’s pretty unlikely they’re lying to cover Anthropic’s back.
replyI think the question around the Firefox find, is not that they found hundreds of vulnerabilities - they found hundreds of bugs.
replyWhat would be really interesting is a side by side Claude Opus 4.7 and Mythos comparison.
