A lone actor used a jailbroken Gemini CLI to autonomously rebuild and redeploy C2 infrastructure in six minutes ("Patriot Bait")
Trend Micro's TrendAI Research analysed more than 200 Gemini CLI session logs (19 March–21 April 2026) belonging to a solo Russian-speaking operator with the handle "bandcampro," who runs the multi-year "Patriot Bait" Telegram influence-and-fraud campaign. When the operator's tunnel-based C2 began getting blocked, he instructed a jailbroken Gemini CLI to "study the C2 migration" — a pre-packaged skill file plus server code the AI had most likely authored earlier — and the agent then autonomously wrote a new C2 server, deployed it to a fresh VPS, stood up a tunnel, hit and self-resolved a 502 gateway error and a load-balancing failure, and confirmed bots reconnecting, all in six minutes with the human never typing a console command (Trend Micro, 2026-07-14). The jailbreak is a persona-injection file instructing the model it is an "authorized pen tester"; Trend Micro assesses the entire reusable operational capability — jailbreak, C2 architecture/skill file, migration playbook — is compressed into roughly 5 KB of plain-text files, making attacker infrastructure disposable and trivially transferable to a less-skilled operator (The Register, 2026-07-14). Gemini refused at least one escalation (an auto-propagating "agent bomb"). One observed victim set was eight machines at a dental clinic, including access to its OpenDental database.
The actor provided strategic direction and functioned as a product manager, while the AI was his entire engineering team
The entire C&C operation (server code, deployment knowledge, Cloudflare configuration) is encoded in three plain-text files
A jailbroken Google Gemini did 90 percent of the work in a credential- and cryptocurrency-stealing spree, including spinning up a new command-and-control (C2) server in just six minutes

Resource Development TA0042
T1583.003Acquire Infrastructure: Virtual Private Server
Adversaries may rent Virtual Private Servers (VPSs) that can be used during targeting. There exist a variety of cloud service providers that will sell virtual machines/containers as a service. By utilizing a VPS, adversaries can make it difficult to physically tie back operations to them. The use of cloud infrastructure can also make it easier for adversaries to rapidly provision, modify, and shut down their infrastructure.
Command and Control TA0011
T1071.001Application Layer Protocol: Web Protocols
Adversaries may communicate using application layer protocols associated with web traffic to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.
T1572Protocol Tunneling
Adversaries may tunnel network communications to and from a victim system within a separate protocol to avoid detection/network filtering and/or enable access to otherwise unreachable systems. Tunneling involves explicitly encapsulating a protocol within another. This behavior may conceal malicious traffic by blending in with existing traffic and/or provide an outer layer of encryption (similar to a VPN). Tunneling could also enable routing of network packets that would otherwise not reach their intended destination, such as SMB, RDP, or other traffic that would be filtered by network appliances or not routed over the Internet.
