Source: kam193 (802483ac3ec3749092037040a0a50ed9fa329232a832ac15fd5a0c692c42a9fd)

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 (a8eff0a6a170a0f178577774f1e72d4ea5cec1f7dc16b59d8d30c581f5706fce)

The OpenSSF Package Analysis project identified 'atlassian-exp' @ 99.0.0 (pypi) as malicious.

It is considered malicious because:

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