The Best Hacker Alive Is an AI. Anthropic Won't Let You Use It
Summary
Anthropic's AI, Mythos, demonstrated unprecedented hacking capabilities by autonomously discovering and exploiting long-standing software vulnerabilities. It found a 27-year-old flaw in OpenBSD, a 16-year-old bug in FFmpeg, and a critical vulnerability in FreeBSD, now tracked as CVE-2026-4747. Mythos also chained multiple Linux kernel bugs into complex attacks and successfully breached a simulated company network in 32 steps, a task typically requiring 20 hours for a human red team. Despite its power, Anthropic has restricted Mythos's public access, instead launching Project Glasswing. This initiative provides Mythos and \$100 million in credits to twelve major companies, including Apple, Google, Microsoft, Amazon, NVIDIA, JPMorgan Chase, and the Linux Foundation, to enhance their defensive capabilities. Anthropic anticipates that similar powerful AI tools will eventually become publicly available.
Key takeaway
For security engineers and teams managing critical software infrastructure, the emergence of AI like Mythos means the window between vulnerability disclosure and exploitation is rapidly closing. You must prioritize immediate patching of all known flaws, rigorously enforce least privilege access across all services, and enhance log monitoring to detect sophisticated, automated attack patterns. Procrastination on fundamental security hygiene now carries significantly elevated risk.
