Anthropic’s Mythos Will Force a Cybersecurity Reckoning—Just Not the One You Think
Anthropic’s Mythos model — capable of finding and exploiting zero-day vulnerabilities at a “shocking level of ability,” per The Register — is either the most consequential AI security release in history or, as some skeptics suggest, a masterclass in pre-IPO narrative building. What’s not in dispute is that the infosec world is paying attention: experts are less worried about Mythos as a hacker superweapon and more concerned it’s exposing just how badly the industry has been sleeping on security hygiene. Either way, Anthropic had a very good week at the HumanX conference, where apparently everyone was talking about Claude — so maybe call it both.
