Background

The pycolorom package, available on PyPI, is purportedly a speed testing or typosquatted Telegram library. It is designed to facilitate interactions with Telegram bots. However, this package has been identified as containing malicious code that allows for remote control of the user's computer, posing significant security risks.

Vulnerability Detail

The vulnerability stems from a malicious campaign identified as '2025-10-speedd-testing-bot'. The package downloads and executes a remote malicious script, effectively turning the user's machine into a remote access tool (RAT). This poses severe risks, including unauthorized access to sensitive information and potential system compromise. The malicious code was introduced by a user identified as 'kam193', and the specific version affected is 1.0.1.

How To Fix

This package is malicious. Remove it and rotate any credentials it could have accessed.

pip uninstall pycolorom

If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
