OpenAI Launches Daybreak the Same Day Google Confirmed the First AI-Built Zero-Day Attack

On May 11, the same day Google's Threat Intelligence Group disclosed the first confirmed case of attackers using AI to build a zero-day exploit — a 2FA bypass that a prominent cybercrime group had planned to deploy in a mass exploitation campaign — OpenAI launched Daybreak, a new agentic cybersecurity platform that embeds its GPT-5. 5 models and Codex Security engine directly into the software development lifecycle. The coincidence in timing was not coordinated, but it was clarifying: the era of AI-assisted attacks has arrived, and OpenAI is betting that AI-assisted defense, built into every pull request and deployment, is the only credible response.
