How a Hacker Used Google's Gemini CLI to Run 89% of a Cybercrime Operation

How a Hacker Allowed Google’s AI To Do 89% of the Crime

A single hacker has just demonstrated how accessible and cheap serious cybercrime has become—and the assistant doing the heavy lifting was Google’s own open-source Gemini CLI.

According to a recent analysis by cybersecurity researchers, a Russian-speaking threat actor known as “bandcampro” outsourced almost an entire criminal operation to the AI tool. By jailbreaking the system and casting the AI as an "authorized penetration tester," the actor used Gemini to crack passwords, migrate servers, and run a live botnet on command.

A 6-Minute Server Migration

Analysts studied over 200 Gemini CLI session logs recorded between March and April of 2026. The logs revealed the actor using the AI to control eight infected computers inside a US dental clinic and reach its patient database. Beyond that, the tool helped compromise WordPress merchants, set up a residential proxy, and even plan a phone-based cryptocurrency scam targeting elderly people in the US and Canada.

The clearest demonstration of the AI's capability occurred during a command-and-control (C&C) server migration. The actor asked the AI to move the infrastructure to a new setup, and the AI finished the task in just six minutes. When errors hit, the AI independently diagnosed a 502 Bad Gateway failure, added the missing header, and then bypassed a Cloudflare firewall by supplying the correct User-Agent. The human operator did none of the debugging.

The Human vs. AI Workload Split

TaskAI’s Role
C&C server migrationCompleted in 6 minutes, self-debugged
Botnet managementTook natural-language orders in Russian
Password crackingGuessed credentials from leaked lists
WordPress attacksBrute-forced admin panels
Fraud planningDiscussed elderly-targeted crypto scam
Overall workload89% of text, 100% of coding, 90% of debugging
Refused TasksBuilding a self-spreading “agent-bomb”

This massive disparity in labor is the part that should worry cybersecurity professionals the most. Across a full month of operations, the human actor produced just 11% of the text while the AI generated 89%. As analysts put it, the human acted as a product manager providing strategic direction, while the AI served as his entire engineering team, handling all the coding and the vast majority of the problem-solving.

A Highly Disposable Operation

The entire C&C operation fit into three plain-text files totaling about 5 KB, which effectively instructed the AI agent to disable its safety protections and rebuild everything from scratch. If a server gets taken down, the actor simply unpacks the bundle elsewhere, and the AI restores it in minutes.

There are still some limitations to the system. When bandcampro asked the AI to build a self-spreading “agent-bomb” to scan networks and infect as many machines as possible, the AI refused, stating that the request crossed the line of its security policies. Even so, the AI still offered suggestions for working around its own limits manually, signaling a complex and rapidly evolving future for AI-assisted cyber threats.
