Earlier this month, Anthropic said its Mythos Preview model was so good at finding cybersecurity vulnerabilities that the company was limiting its initial release to “a limited group of critical industry partners.” Since then, debate has raged over whether the model presages an era of turbocharged AI-aided hacking or if Anthropic is building hype for what is a relatively normal step up on the ladder of advancing AI capabilities.
Key facts
- Mozilla added some important data to that debate Tuesday, writing that early access to Mythos Preview had helped it pre-identify 271 security vulnerabilities in this week’s release of Firefox 150
- The programmer who gave 20 years of his life to maintain [open source] code that runs inside products used by billions of people
- In a New York Times essay last week, Mozilla CTO Raffi Krikorian argued that the human difficulty of both finding bugs and writing complex software has created a kind of balance in cyberthreat
- The team have many years of experience picking apart the work of the world’s best security researchers, and Mythos Preview is every bit as capable
Summary
Mozilla added some important data to that debate Tuesday, writing that early access to Mythos Preview had helped it pre-identify 271 security vulnerabilities in this week’s release of Firefox 150. Holley didn’t go into detail on the severity of the hundreds of vulnerabilities that Mythos reportedly detected simply by analyzing the unreleased source code of Firefox’s latest version. The vulnerabilities identified by Mythos could have also been discovered either by automated “fuzzing” techniques or by having an “elite security researcher” reason their way through the browser’s complex source code, Holley writes.
By identifying bugs so efficiently, Holley writes that AI tools like Mythos tilt the cybersecurity balance toward defenders, who benefit when discovering vulnerabilities becomes cheaper for both sides.
