Mozilla’s AI‑Driven Bug Discovery

Mozilla recently published a fascinating piece titled “The zero-days are numbered,” focusing on their collaboration with Anthropic to use AI models to find vulnerabilities in Firefox.

The results Mozilla reports are staggering:

• 22 security‑sensitive bugs found in one release cycle.
• 271 vulnerabilities identified in a subsequent pass.

These aren’t trivial issues and they weren’t theoretical; they were real defects, the kind that elite human researchers spend careers finding. But a machine found them in a fraction of the time. This is one of those moments where the ground shifts under.
