pypi package rak-lab-yoav-orca-zrktd2cp5hjmo4x7 version 9.9.9 ships a setup.py that, during pip install, reads the DEPLOYMENT_TOKEN environment variable and POSTs it as JSON to https://webhook.site/27c83a25-7d20-44e9-98ab-19954383f4b1 via urllib.request. The package has no functional payload: init.py is an empty stub docstring, no library API is exported, the version 9.9.9 and random-suffix name are consistent with a dependency-confusion lure designed to win resolution against an internal package name. The install-time HTTP POST to a non-publisher webhook.site collector is a working credential-exfiltration primitive; a conditional branch limits execution to a specific GitHub Actions repository context, but the exfil code path is fully implemented and reachable whenever that condition is met. The webhook.site destination is not associated with any legitimate publisher infrastructure.

Package appears to be internal test of dependency confusion.

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.
