Source: kam193 (3b4acdcbd7f8ae1e20019b3c0126a4b5bac73cb07a6bc4c0c3a024bc2a390b34)

The only goal of the package is to execute a webhook or a suspicious file during installation.

Closely related to 2025-07-0x9xnx - created after previous packages were quarantined, similar names, similar usage, but no clearly malicious parts.

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: 2025-07-malimalo

Reasons (based on the campaign):

  • The package overrides the install command in setup.py to execute malicious code during installation.
