- Mozilla integrated 271 vulnerability patches into Firefox 150 after early‑access testing with Anthropic’s Mythos Preview.
- Anthropic released Mythos Preview, an AI model that can automatically generate vulnerability‑inducing test cases across codebases.
- OpenAI is rolling out Codex updates aimed at enterprise coding, marking a divergent focus from Anthropic’s security‑oriented AI push.
- Bobby Holley says AI tools force a universal vulnerability audit, requiring coordinated effort and resources to triage the flood of bugs.
- Firefox 150 contains protections for 271 identified vulnerabilities, a subset of the 151 bugs already fixed by the AI‑driven audit.
Why it matters: Firefox users gain protection against 271 vulnerabilities; attackers lose a cheap bug‑finding channel; Mozilla’s AI‑driven audit forces firms to allocate resources for vulnerability triage, reshaping security budgets.
