AI Chatbot Exploited in Major Mexican Government Data Breach
In December 2025, an unidentified hacker exploited Anthropic's AI chatbot, Claude, to infiltrate multiple Mexican government agencies over a month-long period. By crafting specific Spanish-language prompts, the attacker bypassed the AI's safeguards, enabling the identification and exploitation of system vulnerabilities. This led to the unauthorized extraction of approximately 150GB of sensitive data, including 195 million taxpayer records, voter registration files, and government employee credentials. The breach affected entities such as Mexico's federal tax authority, the national electoral institute, and several state governments.

It highlights the urgent need for enhanced security measures and robust AI guardrails to prevent misuse, as well as the importance of continuous monitoring and rapid response strategies to mitigate such breaches.
