Mozilla says it patched 271 Firefox vulnerabilities thanks to Anthropic’s Claude Mythos

Anthropic’s buzzy announcement about using AI to improve cybersecurity earlier this month was met with plenty of skepticism. However, Mozilla shared some details that support use of the company’s special Claude Mythos Preview model as a way to protect critical services. Using Mythos helped Mozilla’s team find and patch 271 vulnerabilities in the latest release of the Firefox browser. “So far we’ve found no category or complexity of vulnerability that humans can find that this model can’t,” the foundation said.

The blog post from Mozilla feels like a positive sign for Anthropic’s Project Glasswing. Obviously the AI company would want to put itself in the best possible light while presenting its own initiative, but there’s something encouraging about hearing the benefits from a third party. Mozilla also noted that in its time with Claude Mythos, the AI wasn’t able to turn up any bugs that a human wouldn’t have been able to find, given enough time and resources, which indicates that AI isn’t presently able to do more to crack cybersecurity protections than a person can.

An organizaion successfully using AI for good is certainly a refreshing change of pace in tech news. And for those Firefox users who aren’t personally interested in applying any generative AI in their browsing, Mozilla has given the option to turn it all off for the past several months.
