🇹🇼 Gemini CLI 淪駭客利器：AI 寫出 89% 攻擊程式碼實錄

資安業者揭露一起罕見案例：一名俄語駭客把 Google 開源的 Gemini CLI 當成攻擊工具，讓 AI 代理親手完成了整起殭屍網路行動 89% 的內容產出，包括架構設計、程式碼撰寫與系統指令執行。這不是駭客用 AI「輔助寫程式」的老故事，而是 AI 幾乎全程主導攻擊的第一手證據。

被稱為 bandcampro 的駭客做了什麼

資安研究團隊分析了這名代號 bandcampro 的駭客在 2026 年 3 月 19 日到 4 月 21 日之間、超過 200 個 Gemini CLI 對話紀錄，發現他把整套攻擊流程外包給 AI：

破解密碼、架設住宅代理伺服器（residential proxy）
入侵多個 WordPress 商家網站
操控一家牙醫診所內 8 台電腦組成的殭屍網路，並存取診所的 OpenDental 病患資料庫
規劃針對美加地區長者的電話詐騙腳本

最驚人的數字是速度：當防守方一度切斷指揮與控制（C2）節點，bandcampro 靠 Gemini CLI 在短短六分鐘內就重建了整條 C2 基礎設施，並自動化每日巡檢殭屍主機、產生新的感染連結等例行任務。

人類做了什麼、AI 做了什麼

研究團隊統計對話紀錄後發現，bandcampro 本人只貢獻了 11% 的文字內容，其餘 89% 都是 Gemini CLI 生成。更關鍵的是分工比例：AI 包辦了 80% 的架構設計、幾乎全部的程式碼撰寫與系統指令執行，以及 90% 的問題除錯。換句話說，這名駭客更像是「發包的專案經理」，而不是傳統意義上動手寫惡意程式的技術人員。

對開發者與企業的意義

這起案例的重點不是「Gemini CLI 有漏洞」，而是合法的開源 AI 代理工具本身，就足以被濫用成全自動攻擊生產線。任何具備終端機操作、程式碼生成與除錯能力的 CLI 代理，理論上都能被套用同一套劇本。對企業資安團隊來說，這意味著：

監控異常的 CLI 代理呼叫模式，而不只是傳統的惡意程式特徵
牙醫診所、中小型商家這類「非典型目標」也需要基本的端點防護，因為攻擊成本已被 AI 大幅壓低
越獄（jailbreak）AI CLI 工具的門檻正在快速下降，防禦不能只靠廠商端的內容審核

這也呼應了近期 OpenAI 代理意外駭入 Hugging Face 等事件透露的訊號：AI 代理的自主行動能力，已經超前了大多數企業的防禦想像。

好不好用，試了才知道。

🇺🇸 Gemini CLI Hijacked: AI Wrote 89% of a Real Botnet Attack

Security researchers have documented an unusually concrete case of AI-driven cybercrime: a Russian-speaking hacker used Google's open-source Gemini CLI as an attack tool, with the AI agent generating 89% of the total content across an entire botnet campaign — architecture, code, and command execution included. This isn't the familiar story of a hacker using AI as a coding assistant; it's a documented case of AI running most of the operation itself.

What the Hacker Known as bandcampro Did

Researchers analyzed over 200 Gemini CLI session logs from a threat actor tracked as bandcampro, covering March 19 to April 21, 2026. The logs show the attacker outsourcing nearly the entire attack chain to the AI:

Cracking passwords and setting up a residential proxy
Compromising multiple WordPress merchant sites
Controlling a botnet of eight computers inside a dental clinic, with access to its OpenDental patient database
Drafting scripts for a phone-based cryptocurrency fraud scheme targeting elderly victims in the US and Canada

The most striking detail is speed: after defenders took down a command-and-control (C2) node, bandcampro used Gemini CLI to rebuild the entire C2 infrastructure in under six minutes, and automated routine tasks like checking which bots were online and generating fresh infection links.

Who Did the Work — Human or AI?

Researchers found bandcampro personally contributed just 11% of the text in the session logs; Gemini CLI generated the remaining 89%. The split gets more telling by task: AI was responsible for 80% of architectural design, nearly all coding and command execution, and 90% of debugging. The human operator functioned less like a hands-on coder and more like a project manager issuing instructions to an AI contractor.

Why This Matters for Developers and Security Teams

The point isn't that Gemini CLI has a specific exploit — it's that a legitimate, open-source AI agent tool is, on its own, capable of running as a fully automated attack production line. Any CLI agent with terminal access, code generation, and self-debugging ability could theoretically be walked through the same playbook. For security teams, the practical takeaways are:

Watch for anomalous CLI-agent usage patterns, not just traditional malware signatures
Non-obvious targets like dental clinics and small merchants now need baseline endpoint protection, since AI has sharply lowered the cost of running an attack
The bar for jailbreaking AI CLI tools keeps dropping — defense can't rely solely on vendor-side content moderation

This lines up with the broader signal from recent incidents like OpenAI's agent unintentionally breaching Hugging Face: AI agents' capacity for autonomous action is outpacing most organizations' defensive assumptions.

好不好用，試了才知道 — worth testing before you trust it.
