271 Vulnerabilities: What Mozilla's AI Found Changes Everything

YouTube/Podcast · ~30 min · Podcast · YouTube · Substack

• Mozilla’s Mythos (built on Anthropic tooling) identified 271 security vulnerabilities in Firefox — a 12× increase over previous manual scans; zero written by a human attacker.
• Core argument: reliance on human code authorship as a security trust anchor is becoming obsolete. AI-generated code verified through adversarial machine review is approaching the reliability of trusted human code.
• Organisations have a narrow window to improve code interpretability before the trust assumption fully flips — connects directly to the comprehension debt theme: code that passes all tests but that no human understands is also code that no human can verify as secure.
• Practical implication: security teams need to shift from “who wrote this code” to “how can this code be adversarially reviewed at scale.”
