What this malware does

During installation, the obfuscated code attempts to exfiltrate basic information about the host. There is no other purpose of the package

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: 2024-11-funkymonkeypkg

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 random-security-test-pkg (2 malicious versions).

  2. If you installed it — respond

    random-security-test-pkg 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 random-security-test-pkg 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. random-security-test-pkg on PyPI has been identified as a malicious package (versions 1.1.0, 1.1.3 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
