Malicious package

gwpythonsectt2PyPI

Advisory published Updated

gwpythonsectt2 is a confirmed malicious PyPI package (MAL-2025-5116) that steals credentials and exfiltrates sensitive data (malicious version 0.1). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in gwpythonsectt2 (PyPI)

MAL-2025-5116
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall gwpythonsectt2

What this malware does

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: GENERIC-standard-pypi-install-pentest

Reasons (based on the campaign):

  • The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

  • The package overrides the install command in setup.py to execute malicious code during installation.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for gwpythonsectt2 (version 0.1).

  2. If you installed it — respond

    gwpythonsectt2 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 gwpythonsectt2 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. gwpythonsectt2 on PyPI has been identified as a malicious package (version 0.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks gwpythonsectt2-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
