Details

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

Source: kam193 (ec1d3e0940a3c37917b528689547d3728f9f3d0b9e408acc7dcc67435c09d2b0)

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.

Source: ossf-package-analysis (3d92abafc09cf0f7dc822d1020b48ae9cef15a8844d75ec034e30a49af7de3f4)

The OpenSSF Package Analysis project identified 'malinssx' @ 0.0.1 (pypi) as malicious.

It is considered malicious because:

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