Dragos Documents First LLM-Assisted Strike on Water Infrastructure in Mexico

Cybersecurity firm Dragos documented the use of commercial AI models in a cyberattack against a municipal water utility in Monterrey, Mexico. Attackers used Anthropic's Claude and OpenAI's GPT to plan, develop tools, and analyze SCADA systems between December 2025 and February 2026. While they failed to breach operational technology (OT) infrastructure, Dragos warns that commercial AI lowers the barrier for attacks on critical infrastructure.
