OpenAI Launches Daybreak to Find and Fix Security Holes Automatically

OpenAI released Daybreak on 23 June 2026, a system that finds security flaws in computer networks, suggests fixes, and tests them automatically—all in one go. It's aimed at operators of critical infrastructure like power grids and hospitals. The advantage: the AI not only spots problems, it gauges how likely attackers are to exploit them and proposes solutions.
