Google's threat intelligence group reported a criminal group using a zero-day exploit it assessed was likely developed with AI, aimed at a popular open-source web administration tool as part of a planned mass-exploitation campaign. Google worked with the vendor to disclose the flaw early, which it says may have prevented wider use; its chief analyst warned that many more AI-found zero-days are likely out there.
