The First Confirmed AI-Assisted Exploit: 2FA Bypass via Semantic Logic Flaw
On May 11, 2026, Google Threat Intelligence Group (GTIG) identified the first zero-day exploit used by a threat actor that was developed with AI assistance. The exploit targeted a popular open-source web-based system administration tool and enabled two-factor authentication bypass — though valid credentials were still required. GTIG indicated the actor planned mass exploitation, but early discovery and responsible disclosure likely prevented deployment.
