- NCSC’s Richard Horne says hacking AI tools like Mythos Preview can strengthen defenses if security barriers are in place
- Anthropic’s Mythos Preview, part of Project Glasswing, finds zero days at scale
- Horne argues that cutting-edge AI quickly exposes weak fundamentals, giving defenders the opportunity to decisively outmaneuver cybercriminals.
With proper safeguards and security standards, hacking AI tools like Mythos Preview can be a net positive for cybersecurity defenses everywhere, says Richard Horne, director of the National Cyber Security Center (NCSC).
According to the BBC, Horne echoed these statements in a speech at the NCSC’s annual CyberUK conference on Wednesday.
“As we’ve seen in the media in recent days, cutting-edge AI is rapidly enabling the discovery and exploitation of existing vulnerabilities at scale, illustrating how quickly it will expose where the fundamentals of cybersecurity still need to be addressed,” he said.

this time it’s different
Earlier this month, Anthropic announced a new security initiative called Project Glasswing and, at its core, the newest AI model, Mythos Preview. Apparently, this model was so good at discovering and exploiting zero-day vulnerabilities that Anthropic decided to give it to only a handful of large software companies. That way, these companies can gain an advantage against bad actors, before the model is released to the general public at a later (as yet undetermined) date.
There’s also a lot of talk online about this being just a PR stunt, with some people claiming that OpenAI did the same thing with GPT-2, which later turned out to be much more benign.
However, this time it really could be different. The Mozilla Foundation said that with the help of Mythos it managed to find 271 vulnerabilities in Firefox 150, the latest version of the famous browser. When he tried something similar with an older model (Opus 4.6 against Firefox 148) he found “only” 22 errors.
Announcing the results, Mozilla CTO Bobby Holley couldn’t hide his excitement and hinted that the cat-and-mouse fight against cybercriminals might finally come to an end.
“Our work is not done, but we have turned the corner and can see a much better future than simply keeping up,” he wrote. “The defenders finally have a chance to win decisively.”
