OpenAI Launches GPT-6 Cyber After AI Helps Find 81 Firefox Flaws, 948 Linux Exploits

The Hacker News · 3h ago

The Brief

OpenAI launched GPT-6 Cyber, a version of GPT-6 Astra built to find software vulnerabilities, test how attackers could exploit them, and help develop fixes.
OpenAI says the model found 81 previously unknown vulnerabilities in Firefox, and Security Affairs reports they were high-severity, plus hundreds of Linux bugs.
OpenAI says GPT-6 Cyber beats GPT-5.6 Cyber at exploitation and goes out of scope less often, and it is designed for authorized security testing of websites and applications.

Why it matters

Security teams and maintainers may get a tool that finds and exploits bugs faster, so the same capability could also be used by attackers. Developers should expect more AI-found vulnerability reports in widely used software.

Who’s affected

Firefox maintainers and users
Linux kernel and software maintainers
Security teams doing authorized testing of websites and applications
