According to CoinMeta, OpenAI announced the launch of GPT-6 Cyber, upgrading its network security capabilities from high to critical. This model has identified 81 previously unknown high-severity Firefox vulnerabilities and has helped to identify and develop effective exploitation methods for 948 Linux kernel vulnerabilities, including 588 issues that were previously unknown. GPT-6 Cyber is currently being rolled out to some Daybreak Red customers, with plans to expand access in the coming weeks. OpenAI also warned that attempts by malicious actors to abuse the network security model are on the rise.
