# Anthropic's AI finds security bugs faster than Microsoft can patch them

*2026-07-29 · Source: [Ars Technica](https://arstechnica.com/security/2026/07/anthropic-is-finding-bugs-faster-than-microsoft-can-fix-them/)*

Anthropic is using AI-assisted vulnerability research to find bugs in Microsoft products faster than Microsoft's own team can fix them, according to Ars Technica. Microsoft is reportedly racing to patch exploits before external hackers find them independently.

**Why it matters:** This illustrates how AI is shifting the economics of vulnerability discovery: automated bug-hunting can now outpace a major vendor's patch cycle, a boon for defenders who adopt it first but a risk once similar tools reach adversaries. It follows Anthropic's Claude model separately finding cryptographic weaknesses, reinforcing AI's growing role on both sides of security research.

**Topics:** research, policy
