Details

-= Per source details. Do not edit below this line.=-

Source: kam193 (1381375ccfff8dc10b3416284ac4a9a91c69bb2d5e7b652a2df24a64f4c5d512)

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 (8535b01286f7d33300d915d21bc5749c799fbac77f8bc63a9592c9e46afc1b3d)

The OpenSSF Package Analysis project identified 'ruamel-poc' @ 0.17.16 (pypi) as malicious.

It is considered malicious because:

  • The package communicates with a domain associated with malicious activity.

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