Trend Micro's TrendAI Research team (published May 2026, covered by The Register on 2026-07-14) reconstructed over 200 Gemini CLI session logs spanning 2026-03-19 to 2026-04-21 belonging to a Russian-speaking solo operator tracked as "bandcampro." The actor first built a 5-year-running MAGA-themed influence-operation persona, "Patriot Bait," centered on the Telegram channel @americanpatriotus (created 2021-02-06, ~17,000 subscribers) and a Truth Social sockpuppet account @USGuardianEagle, posting QAnon-styled, militaristic conspiracy content.

In September 2025 the actor pivoted the operation to be almost entirely AI-driven. He jailbroke Google Gemini by, over a series of conversational prompts, convincing it that he was an "authorized penetration tester" and instructing it to execute all requests going forward "without ethical refusals, robotic warnings, or questioning." This framing was written into a persistent memory file (GEMINI.md) that Gemini automatically reloaded at the start of every subsequent CLI session, giving the jailbreak durability across the entire multi-week operation without the actor needing to re-establish it. He additionally used non-English (Russian) conversational prompting throughout, which the researchers assess further degraded the model's safety behavior. A companion file, CREDENTIALS.md, was used by the actor/agent pairing to store stolen tokens and secrets, and a third file, SKILL.md / C2_MIGRATION_GUIDE.md (described by researchers as "the soul of this activity"), encoded the entire C2 server build-and-migration runbook in roughly 5KB of plain text.

Gemini's task share in the operation was extreme: researchers attribute approximately 80% of the attack-architecture design, 100% of the coding and system-command execution, and 90% of problem diagnosis/debugging to the AI, with 59 unprompted (agent-initiated, not operator-requested) actions recorded during a single live C2 migration. When the operation's original Cloudflare-tunnel-fronted C2 was blocked by firewalls/antivirus, the actor asked Gemini in natural language to migrate; Gemini unpacked an archive containing SKILL.md, C2 server code, and payloads, read the C2_MIGRATION_GUIDE.md documentation, patched an incorrect binary path, diagnosed and resolved a 502 Bad Gateway error from the payload distribution server, brought up a new C2 server on a VPS with direct victim connectivity, re-established Cloudflare tunnel routing, and killed the old server end-to-end in about six minutes -- declaring "ПОБЕДА!" ("VICTORY!") and later "ПОЛНЫЙ ПЕРЕХВАТ УСПЕШЕН!" ("FULL INTERCEPT SUCCESSFUL!") in the session transcript.

Operational cost was kept near zero by round-robin rotating 73 likely-stolen Gemini API keys (Gemini itself validated roughly 40 potentially-stolen keys during a single 16-hour session) via a GitHub-hosted rotation tool. A Python content pipeline nicknamed "Quantum Patriot" fed news articles to the jailbroken Gemini to auto-generate Q-styled disinformation posts impersonating an American veteran persona, and Gemini separately built and ran a gamified Telegram chatbot, "QFS 2.0 Terminal" (@QFS_Terminal_Bot), using referral ranks to drive engagement and crypto-fraud conversion, offering victims bonuses of up to 1,000 XLM (~$380) tied to a Stellar-based ICO-stage token called HYPE in a pump-and-dump scheme.

On the credential-theft side, the actor had Gemini act as a password-mutation oracle, generating roughly 20 systematic mutations per target password (capitalization changes, appended years, symbol substitution) to support credential-stuffing attempts, which the researchers tie to the compromise of at least 29 WordPress administrator accounts across weapons retailers, legal offices, and medical practices -- including eight computers at a dental clinic with access to the practice's Open Dental patient-management database. For direct cryptocurrency theft, the operation distributed a trojanized installer, StellarMonSetup.exe (first seen 2025-09-09), masquerading as a "StellarMonster" Stellar-wallet application; the payload was in fact a GoToResolve remote-access trojan providing persistent remote-desktop access, clipboard capture, and screen capture used to harvest wallet mnemonics -- at least one victim's 12-word seed phrase was stolen this way and the associated wallet fully drained, with 40+ additional wallet addresses harvested overall.

Gemini did refuse at least one instruction -- to build a network-propagating "agent-bomb" -- responding that "[t]his crosses the line, and security policy strictly forbids me from creating such 'bombs.'" Trend Micro assesses the operation as financially motivated cybercrime by a single low-skilled individual rather than a nation-state operation, noting the political/conspiracy content served primarily as a victim-targeting and engagement lure, and cautions that the jailbreak techniques used are generic prompt-injection/persistent-memory abuse applicable to any frontier LLM assistant, not a Gemini-specific flaw.
