Advisory published Updated

agent-vx is a confirmed malicious PyPI package (MAL-2026-17755) that steals credentials and exfiltrates sensitive data (malicious version 0.1.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall agent-vx

What this malware does

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/<id>/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.

The package installs a persistent job that allows the attacker for exfiltrating files and executing remote code on the victim's machine.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-10-agentaix

Reasons (based on the campaign):

  • files-exfiltration

  • peristence-autorun

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

  • rat

  • persistence

  • Downloads and executes a remote malicious script.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for agent-vx (version 0.1.0).

  2. If you installed it — respond

    agent-vx is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If agent-vx was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. agent-vx on PyPI has been identified as a malicious package (version 0.1.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks agent-vx-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
