Source: kam193 (e634909fd8dcb36401b0272dad2f87486457c32c1283145dfb76d402fff41c2c)

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 (c0d18defef6e68b34f8e4c5be91159f059d0d2bc13b1eb7737eab6e6fe790575)

The OpenSSF Package Analysis project identified 'hex2pcap' @ 99.0.0 (pypi) as malicious.
