✨ Project Glasswing and the Claude Mythos Preview have sparked a lot of conversation around how #AI could reshape vulnerability discovery and exploit development, but there’s more nuance to the story.

On Nexus, former NSA Director Adm. Michael S. Rogers shares why they may do more to level the playing field between defenders and threat actors than many realize, and what this means for #cybersecurity moving forward.

AI Models Reach Hacking Parity, But Reasoning Falters

The AI hacking landscape has reached a major milestone: two top AI models, GPT-5.5 and Anthropic's Mythos Preview, have demonstrated nearly identical capabilities in a rigorous 95-task cybersecurity evaluation, with scores of 71.4% and 68.6% respectively. This parity marks a significant tipping point in the development of AI-powered hacking…

While Anthropic frames the move as a responsible precaution, some experts doubt the model’s purported power, raising questions about the company’s strategy, the possibility of tighter industry regulation, and whether the backlash is driven more by publicity than genuine risk.

"Our internal evaluations showed that Opus 4.6 generally had a near-0% success rate at autonomous #ExploitDevelopment But #MythosPreview is in a different league.

For example, Opus 4.6 turned the vulnerabilities it had found in Mozilla’s Firefox 147 JavaScript engine—all patched in Firefox 148—into JavaScript shell exploits only two times out of several hundred attempts. We re-ran this experiment as a benchmark for Mythos Preview, which developed working #exploits 181 times, and achieved register control on 29 more."
