Source: kam193 (638020a87c6e1aaf4b8542a5b20723a6ed900b986bfd407c8bf55aad3016933f)

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.

Source: ossf-package-analysis (a9622e8d5bdc036e8502ca1158478c805862e882dc7a27f493b01dff9ae76115)

The OpenSSF Package Analysis project identified 'initialtestingdonotpull1235' @ 3.0.1 (pypi) as malicious.

It is considered malicious because:

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