Anthropic’s Cybersecurity Shock Wave + Ronan Farrow and Andrew Marantz on Their Sam Altman Investigation + One Good Thing

Anthropic announced Project Glasswing and its Claude Mythos preview model, which reportedly found critical zero-day vulnerabilities in OpenBSD and FFmpeg, prompting a consortium of major tech firms to conduct defensive cybersecurity testing. The model is not being released publicly due to its potential for misuse, with Anthropic arguing that proactive hardening of infrastructure is necessary. Experts like Alex Stamos suggest this could trigger a massive global software patching effort within six months.

You’ll understand how AI is shifting from tool to autonomous threat actor in cybersecurity, with real examples of exploits found in foundational software.

1. 01Claude Mythos preview found a 27-year-old security flaw in OpenBSD and a previously undetected bug in FFmpeg despite 5 million prior scans.
2. 02Anthropic is restricting access to the model, sharing it only with a consortium including Microsoft, Apple, and Amazon for defensive cybersecurity use.
3. 03The rollout reflects a shift toward AI-driven, autonomous discovery of zero-day exploits at speeds far beyond human teams.
