🚨 Hacker Uses Claude and ChatGPT to Breach Multiple Government Agencies Source: cybersecuritynews.com/hacker… A single threat actor compromised nine Mexican government agencies and stole hundreds of millions of citizen records in a highly sophisticated cyberattack. The campaign, which ran from late December 2025 through mid-February 2026, highlights a dangerous shift in the modern threat landscape. The attacker used Anthropic’s Claude Code and OpenAI’s GPT-4.1 not just for planning, but as core operational tools that drastically accelerated the attack.
