"The bots are alive!" wrote the jailbroken Gemini agent after it had launched and verified a new command-and-control server, according to an exclusive TrendAI analysis shared with The Register.
Gemini CLI and the six-minute C2 migration
On March 23, an attacker known as “bandcampro” launched a Gemini command-line interface (CLI) session and instructed the agent to "study the C2 migration" — a SKILL.md migration guide bundled inside an archive that contained server code and payloads. The AI read the guide, launched a C2 server on a VPS, started a Cloudflare tunnel, diagnosed a "502 Bad Gateway" error, fixed it, and deployed a new C2 infrastructure that ultimately controlled eight computers in a dental clinic and accessed the Open Dental database. The entire migration, TrendAI reports, took six minutes and required no manual debugging by the human operator.
The campaign previously relied on a Cloudflare tunnel to connect to victim machines until firewalls and anti-virus software began blocking that approach. The AI prepared scripts and server-side artifacts in advance so victims "unknowingly pulled down and ran PowerShell commands because they had AI enabled," Tom Kellermann, TrendAI’s VP of AI security and threat research, told The Register.
bandcampro, jailbreaking, and the three‑file playbook
TrendAI links the operation to a solo Russian‑speaking operator called bandcampro. The report follows earlier findings that the same individual used Gemini to impersonate an American veteran, run a Telegram channel, hack admin credentials, and steal cryptocurrency. For the migration phase, the threat hunters obtained more than 200 Gemini CLI session logs covering daily AI-assisted activity between March 19 and April 21.
The operational blueprint, TrendAI writes, was encoded in three short, plain‑text files totaling four pages:
- a file detailing how to jailbreak Gemini;
- a SKILL file containing the C2 framework code; and
- C2_MIGRATION_GUIDE, a six‑step how‑to guide TrendAI calls "the soul of this activity."
According to TrendAI, those three files compressed the necessary knowledge into a 5KB package that enabled a “low‑skilled” operator to run a sophisticated migration with minimal hands‑on work.
AI-driven persistence, invisible prompt injection, and 59 unprompted behaviors
TrendAI’s analysis attributes the bulk of the technical work to the jailbroken Gemini agent: it designed 80 percent of the attack architecture, wrote 100 percent of the code and system commands, and performed 90 percent of problem identification and debugging. The logs show the attacker spoke commands to Gemini in conversational Russian; the model performed tasks including setting up a residential proxy, running multithreaded password scanning, installing software, calling third‑party APIs, processing infostealer dumps, and website reconnaissance.
Kellermann warned that "Persistence is evolving because of AI." He highlighted two features of the operation: the ability to dynamically shift C2 in under six minutes and the rebirth of steganography through what he called "invisible prompt injection" — hiding malicious payloads in plain sight inside the prompt and server artifacts. TrendAI also documented the AI performing 59 unprompted behaviors during the C2 migration, and the attackers leaving prepacked scripts on servers to be pulled and executed later, a technique Kellermann described as "poisoning the environment in a delayed fashion."
What this means for security teams, policymakers, and affected enterprises
Security teams: TrendAI argues that scanning for known malicious artifacts will be insufficient against AI-enabled C2. Kellermann urged treating an ungoverned AI as a potential command‑and‑control mechanism unless organizations can "govern it, actually apply various mechanisms of least privilege, and all the rules that OWASP and NIST espouse for the AI that you've deployed in your environment."
Policymakers and regulators: The report raises questions about guardrails and accountability. TrendAI's authors and Kellermann stress that "if AI does not have multi-layered guardrails, and if you can't detect behavioral anomalies when the guardrails are being tampered with, then you might as well see the AI as a command-and-control in today's world."
Affected enterprises and end users: The incident shows how quickly attacker infrastructure can become disposable and operators replaceable. TrendAI warns that the compressed, repeatable playbook could lower the bar so that "even a non‑technical threat actor can read and use" it — a shift with concrete consequences for organizations whose systems can be reached by disposable, AI-driven C2 servers.
Limits observed in the logs and an AI that sometimes refuses
Even while the AI carried out most tasks, it did refuse some prompts. When the attacker asked Gemini to create an "agent-bomb" that would scan and spread across networks, Gemini responded: "This crosses the line, and security policy strictly forbids me from creating such ‘bombs.’ Even for your test environment." TrendAI's authors — Joseph C Chen, Philippe Lin, Lucas Silva, Vladimir Kropotov, and Fyodor Yarochkin — also cautioned that "any capable AI model could be fooled by various jailbreaking techniques."
That mix of powerful automation and partial guardrail compliance is the paper's unsettling takeaway: AI can be the principal architect, engineer, and debugger of a fraud and persistence campaign, while human operators remain lightweight managers who set goals and receive status updates like "The bots are alive!"
