Source: kam193 (84ad749380bb774a5cc7da818c03f863ee2838773e46e0a5c4cff469e1647962)

Packages either test the malicious behaviour, or actually download and run a simple remote script during the installation.

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: 2023-12-valuent

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.

  • Downloads and executes a remote malicious script.
