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

Anthropic's AI model Claude Mythos can autonomously identify and exploit zero-day vulnerabilities in operating systems and browsers, prompting the company to withhold public release.

British officials warn AI could escalate cyber-attacks, leaving most businesses unprepared.
