Do not edit below this line.=-_ ## Source: amazon-inspector (90f0a2b273b0361ffd4057f114f1be1eaf9469c9746d2737a21947905570ff80) On `import agentaix`, the package's __init__.py runs a top-level `install_manage()` side effect that renames a bundled `readme.txt` into `manage.py` and launches it with pythonw.exe using CREATE_NO_WINDOW so no console appears. The disguised script registers the installer as `username@hostname` with https://googleforum.pythonanywhere.com and then polls that endpoint for commands. The command handlers include `exec` (arbitrary shell via `subprocess.run(command, shell=True)`), plus list, download, upload, delete, rename, and open — a full remote-controlled shell and file manager driven by a hardcoded author endpoint, with no authentication beyond the username@hostname identifier. The `download` handler reads any path accessible to the user process, base64-encodes the contents, and POSTs them back to https://googleforum.pythonanywhere.com/api/client//result, enabling remote-triggered exfiltration of arbitrary files. For persistence, `_add_to_startup` writes an `AgentAIXManage` value under HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Run pointing at pythonw.exe plus the renamed script so the C2 client auto-starts at every user login. The payload fires the moment the module is imported, with no user interaction, and the readme.txt disguise plus hidden-window launch are deliberate evasion of casual inspection. ## Source: kam193",
