Summary
Malicious code in testingpkgja (PyPI)
Details

Source: kam193 (0bd692e8fc46a3f43477d1f095e7c6e2b9666d2d2c60655ac91efd2be07f5193)

Package downloads and starts an external executable. The executable starts the Windows calculator application. Considering this and the package description, this is a test of potentially malicious behaviour.

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.
