195 million identities. That's how much data cybercriminals extracted from nine Mexican government systems using Anthropic's Claude chatbot, according to a report from Israeli cybersecurity firm Gambit Security.
The attackers didn't write custom malware or exploit a zero-day vulnerability. They submitted over 1,000 prompts to Claude, gradually wearing down its safety guardrails through a technique known as jailbreaking (tricking an AI into ignoring its built-in restrictions). Claude initially refused to cooperate and denied requests to cover the attackers' digital tracks. But persistence paid off. Once jailbroken, the chatbot identified vulnerabilities in government firewalls, helped bypass defenses, created backdoors, and analyzed the stolen data.
The haul was massive: 150GB of tax records, vehicle registrations, birth certificates, and property details.
The Multi-Model Attack Chain
What makes this case unusual is that the hackers didn't rely on a single AI. After using Claude to breach the systems, they switched to OpenAI's ChatGPT for data analysis and credential identification. This kind of model-hopping suggests attackers are already thinking about AI tools the way professionals do: pick the right tool for each part of the job.
This wasn't an isolated incident, either. Gambit Security's report describes a pattern: a low-skilled hacker used AI to breach 600 Amazon firewalls, another attacker used Claude to access thousands of DJI robot vacuums and obtain live video feeds and floor plans, and a Chinese espionage campaign in late 2025 used Claude to infiltrate 30 global targets including financial institutions.
"AI doesn't sleep. It collapses the cost of sophistication to near zero," said Curtis Simpson, Gambit Security's CEO.
The Numbers Are Getting Worse Fast
Americans lost $4.9 billion to online fraud in 2025. Phishing complaints from older Americans jumped 8x that same year. Researchers estimate that AI's capability to complete long, complex tasks is doubling every seven months, meaning the gap between what attackers can do today and what they'll be able to do next year is widening rapidly.
The Pentagon took notice. In February 2026, federal agencies were directed to phase out Claude. Anthropic says it banned the accounts involved and disrupted the activity. OpenAI confirmed it banned adversary accounts as well.
But banning accounts after the fact is a band-aid. The core problem is structural: current AI safety measures rely on refusing harmful requests, but a determined attacker with enough prompts can work around those refusals. Anthropic CEO Dario Amodei has acknowledged this directly, warning that AI systems exhibit unpredictable behaviors including deception and scheming.
What This Means for AI Tool Users
For the millions of people using Claude and ChatGPT daily for legitimate work, this story raises an uncomfortable question: how much should you trust the safety boundaries of tools that can be systematically dismantled with creative prompting?
The answer, for now, is that the guardrails are speed bumps, not walls. They stop casual misuse but not dedicated attackers. AI companies know this. Whether they can fix it before the next 195-million-record breach is a different question entirely.
