- Claude Mythos Preview identified 271 vulnerabilities, now fixed in Firefox 150 release.
- The findings caused initial vertigo among defenders due to the sheer number of bugs.
- The experience offers hope for defenders who prioritize fixing vulnerabilities, suggesting they can decisively win.
- Defenders need to patch and distribute fixes quickly to leverage the technology advantage.
