**Severity:** Critical **Affected versions:** `= 100.1337` ## Source: kam193 (3e752a2e84135761f1cf5319ed23d3a78b994ea011df850c87938442ad249180) 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. --- Credit: [OpenSSF](https://github.com/ossf/malicious-packages) ([source](https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/wr-test/MAL-2025-1008.json)) **References:** - https://bad-packages.kam193.eu/pypi/package/wr-test - https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/wr-test/MAL-2025-1008.json - https://github.com/advisories/GHSA-86v4-4762-g2f6
