What this malware does

Packages that might be part of testing for pentesting / malicious activity / joy, with suspicious activity that does not present any real harm.

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-simple-tests

Reasons (based on the campaign):

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

The OpenSSF Package Analysis project identified 'soultracker' @ 0.1.0 (pypi) as malicious.

It is considered malicious because:

  • The package executes one or more commands associated with malicious behavior.

Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for soultracker (version 0.1.0).

  2. If you installed it — respond

    Remove soultracker from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If soultracker 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. soultracker 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 soultracker-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
