Mythos Preview Sparks a Security Reboot for Software

Anthropic’s Claude Mythos Preview can identify vulnerabilities across systems and autonomously develop exploits, a capability the company says will force a cybersecurity rethink. It’s being tested with Project Glasswing among a limited group of tech giants to give defenders a head start, but experts are divided: some see it as a real threat that could accelerate exploit chains and zero-click attacks, while others view it as hype. Regardless, the rollout is framed as a wake-up call to move toward secure-by-design software and machine-scale defenses rather than relying solely on patching and reaction.
