Anthropic shows Claude shrinking the attack surface of code

Summary

Anthropic published early research on using Claude for automated attack surface analysis and reduction. Claude reviewed 25 open-source projects of more than five million lines, inventoried over 17,000 configuration options, and found 493 issues such as code reachable before authentication. Instead of fixing vulnerabilities one by one, the approach restricts unnecessary reachability so that unknown flaws become harder to exploit. All figures come from Anthropic's own research.

Why it matters for our work

Security teams get a concrete example of delegating repetitive code review to AI while humans keep judgment and sign-off. As AI-assisted coding produces more code, automated surface reduction becomes more valuable.
