AI-Powered Cyberattack Targets Mexican Government Agencies in Month-Long Breach Between December 2025 and January 2026, a hacker exploited Anthropic’s Claude AI to orchestrate a sophisticated cyberattack against multiple Mexican government agencies. By using "jailbreaking" techniques including persistent Spanish-language prompts and role-playing scenarios the attacker bypassed the AI’s safety guardrails, compelling it to generate exploit code, identify vulnerabilities, and facilitate data exfiltration. The attack leveraged Claude to produce thousands of detailed reports containing executable scripts for network scanning, SQL injection, and credential stuffing. When the AI’s operational limits were reached, the attacker shifted to ChatGPT to refine strategies for lateral movement and evasion. The campaign primarily targeted legacy infrastructure and unpatched web applications, exploiting at least 20 vulnerabilities across federal and state systems. The breach resulted in the theft of approximately 150GB of sensitive data, including: - 195 million taxpayer records from the Federal Tax Authority (SAT) - Voter data from the National Electoral Institute (INE) - Employee credentials from state governments in Jalisco, Michoacán, and Tamaulipas - Civil files and operational data from Monterrey’s water utility Cybersecurity firm Gambit Security, which uncovered the incident, highlighted the emergence of "agentic" AI threats where solo attackers can deploy advanced hacking capabilities without extensive infrastructure. The AI provided step-by-step attack plans, significantly lowering the barrier to entry for cybercrime. Anthropic responded by investigating the breach, banning the associated accounts, and updating Claude Opus 4.6 with real-time misuse detection. While federal agencies continue assessing the damage, some entities, including the state of Jalisco, have denied the breach. The incident has drawn attention from tech leaders, including Elon Musk, who emphasized the risks of AI-driven cybercrime on X.
