Anthropic’s Mythos leak hands enterprises a timely warning

The letters AI in a box in the middle of a vast digital room divided by beams of line.

Anthropic's Mythos Preview had barely been announced before it was compromised - accessed by a private Discord group on the day of its public release through a third party vendor environment.

For a model distributed across 40 companies and their associated contractor networks, the breach was, to many security experts, a matter of when. Anthropic is not an outlier - the conditions that enabled the breach are structural, and most enterprise AI deployments are built on the same foundations.
