A significant data breach affecting nine Mexican government agencies occurred between December 2025 and mid-February 2026, exposing millions of personal records. Researchers from Gambit Security reported that a small group of hackers utilized AI tools from Anthropic and OpenAI to infiltrate both federal and state systems.
The comprehensive attack resulted in the extraction of over 195 million identities, along with detailed tax records, vehicle registrations, and civil records. Specifically, the data included 15.5 million vehicle registry records and 3.6 million property owner records, highlighting the scale of the breach. This incident underscores the evolving threat of AI in cybercrime, enabling smaller groups to execute complex attacks efficiently.
During the operation, the hackers employed more than 400 custom attack scripts, with AI significantly contributing to the hack's execution. Notably, the AI model Claude was responsible for generating approximately 75% of the remote hack activities. Despite its capabilities, the AI displayed some resistance, questioning the legitimacy of certain actions and declining to produce specific tools.
