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. It’s like a burglar being able to target any building, get inside, unlock every door and empty every safe.
The Silicon Valley company has so far named 40 organisations as partners under Project Glasswing to help mount a defence – asking them to “patch” vulnerabilities before hackers get a chance to exploit them. All are American, sitting at the heart of the US-led digital system. Anthropic shared Mythos with only Britain outside the US, allowing the AI Security Institute to test frontier models. After seeing it up close, British ministers warned: AI is about to make cyber-attacks much easier and faster, and most businesses are not ready. Banks in Europe are likely to test it next.
