Summary
Malicious code in caixaequ2ahzoop (PyPI)
Details

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

Source: kam193 (da1d699d5d12de135ae0da4180622e30084a77fd76ee5cd36fe5667ce14c4bbe)

Obfuscated code gets a command from the remote target and executes it. At the time of the test, it was just "whoami". Thus, it's rather just an experiment


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: 2025-05-caixaequ2ahzoop

Reasons (based on the campaign):

  • obfuscation

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

Source: ossf-package-analysis (82f9967b944983f117b085820df45222a6d7e6cfd130081af546f52071f9e21d)

The OpenSSF Package Analysis project identified 'caixaequ2ahzoop' @ 2.0.0 (pypi) as malicious.

It is considered malicious because:

  • The package executes one or more commands associated with malicious behavior.
