The Guardian view on Anthropic’s Claude Mythos: when AI finds every flaw, who controls the internet?

Tech can scale cyber-attacks and defences alike, raising questions about private power, public risk and the future of a shared internet Anthropic announced its latest AI model, Claude Mythos, this month but said it would not be released publicly, because it turns computers into crime scenes. The company claimed that it could find previously unknown “zero-day” flaws, exploit them and, in principle, link these weaknesses in order to take over major operating systems and web browsers. Mythos did so autonomously, writing code and obtaining privileges. The implications are significant.
