And while this tech industry anti-rogues’ gallery scans their own systems with the purportedly perspicacious Mythos, Anthropic invited around 40 other organizations to participate in this introspective bug hunt, subsidized by up to $100M in usage credits for Mythos Preview and $4M in direct donations to open-source…
Key facts
- Mythos is markedly different from Claude Opus 4.6, which Anthropic only recently said was not skilled at developing working exploit code
- The 22 Anthropic researchers listed as authors of its Tuesday post insist that the vulns are often subtle and difficult to detect
- The AI biz calls its limited release initiative Project Glasswing
- What Anthropic is describing is a zero-day engine: "Engineers at Anthropic with no formal security training have asked Mythos Preview to find remote code execution vulnerabilities overnight
Summary
For years, the infosec community’s biggest existential worry has been quantum computers blowing away all classical encryption and revealing the world’s secrets. "AI models have reached a level of coding capability where they can surpass all but the most skilled humans at finding and exploiting software vulnerabilities," the company said. Mythos is markedly different from Claude Opus 4.6, which Anthropic only recently said was not skilled at developing working exploit code. What Anthropic is describing is a zero-day engine: "Engineers at Anthropic with no formal security training have asked Mythos Preview to find remote code execution vulnerabilities overnight, and woken up the following morning to a complete, working exploit. Fortunately, instead of releasing Mythos, Anthropic chose to provide a preview version to a set of industry partners so they can use it to find flaws in their systems before adversaries do.
