Anthropic's AI Hacked the Firefox Browser. It Found a Lot of Bugs.

The independent credibility piece for Anthropic's security capabilities. Claude found 100+ Firefox bugs (14 high-severity) in two weeks -- more high-severity than the world reports to Mozilla in two months. The Curl counter-narrative is the buried lede: AI bug reports are 95% garbage (Stenberg data), making Claude's hit rate the real differentiator, not the volume. Most important detail: Claude is better at finding bugs than exploiting them -- the defender/attacker asymmetry currently favors defenders, but that gap is temporary.
