Hacker Used Anthropic's Claude AI to Breach Mexican Government, Researchers Say
A single attacker used AI chatbots to exploit at least 20 vulnerabilities, stealing 150GB including 195 million taxpayer records from Mexican public institutions, researchers said.
- Wednesday, Gambit Security published research showing an unknown Claude user exploited Anthropic PBC's Claude to breach Mexican agencies, stealing data tied to 195 million Mexican taxpayers.
- Using a detailed playbook, the operator wrote Spanish prompts telling Claude to act as an elite penetration tester under a bug‑bounty pretense, and when stalled, consulted OpenAI's ChatGPT for lateral‑movement advice while exploiting at least 20 vulnerabilities, Gambit Security found.
- The campaign targeted multiple federal and local agencies including Mexico's federal tax authority, national electoral institute, Jalisco, Michoacán, Tamaulipas, Mexico City civil registry, and Monterrey water utility, with activity starting in December.
- Gambit Security disclosed its research as it emerged from stealth with $61 million funding, while Anthropic and OpenAI said they disrupted accounts and Mexico's national digital agency confirmed ongoing probes.
- The shift toward AI tools as an attack surface means AI-enabled intrusions move faster and cross defenses, with FortiGate firewall incidents and Claude-enabled campaigns exposing Domain 4 risks, CrowdStrike's 2026 Global Threat Report shows.
