Details

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

Source: kam193 (bebd39f4de86af5e9634fbfda5f8c97794b597b1066c2fcd32e3a2068569280d)

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 (4335bf56e5be8695fa87d7678b21eb5080d33a35c0c0f6b0278a4555ae5b1f2a)

The OpenSSF Package Analysis project identified 'testing123kk' @ 10.0.5 (pypi) as malicious.

It is considered malicious because:

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