Mozilla: Anthropic's Mythos Found 271 Security Vulnerabilities in Firefox 150
Mozilla said the Firefox team patched 271 vulnerabilities found with early access to Anthropic's new model as AI bug hunting accelerates.
- On Tuesday, Mozilla released Firefox 150, which includes protections for 271 vulnerabilities identified using early access to Anthropic's Claude Mythos Preview.
- Firefox Chief Technology Officer Bobby Holley stated that emerging AI tools create a necessary 'bootcamp' for software, forcing developers to fix latent vulnerabilities before attackers exploit them.
- Previously using Anthropic's Opus 4.6 model, the team found 22 bugs in Firefox 148, though AI currently cannot identify vulnerabilities that an elite human researcher could not.
- Describing the vulnerability haul as 'light at the end of the tunnel,' Holley asserted that 'defenders finally have a chance to win, decisively' against cyber threats.
- Because every piece of software has bugs now discoverable by AI, The Mozilla Foundation warned that all software must undergo this critical security transition.
