AI-Developed Zero-Day Exploit Used in Mass Exploitation Attempt, Mandiant Warns

Forensic Summary

Google's Threat Intelligence Group (GTIG) has identified, for the first time, a criminal threat actor using a zero-day exploit believed to have been AI-generated, intended for mass exploitation before proactive counter-discovery intervened. The report also documents AI-augmented malware development, autonomous attack orchestration via AI-enabled malware (PROMPTSPY), and obfuscated LLM access pipelines used by adversaries to bypass usage controls. Nation-state actors from China and North Korea are actively pursuing AI-assisted vulnerability discovery, marking a significant escalation in adversarial AI capability.
