Background

The dzuseragents package, available on PyPI, is designed to manage user agent strings for web requests. However, it has been compromised to include malicious functionality that allows it to download and execute a remote executable, posing significant security risks to users. This package is intended for developers looking to customize user agent strings but has been exploited for malicious purposes.

Vulnerability Detail

The dzuseragents package contains malicious code that downloads an executable from a remote server and adds it to the system's autostart. This executable takes screenshots periodically and sends them to a Discord channel, effectively acting as spyware. The vulnerability originates from the package's source code, which has been modified to include these harmful actions, leading to potential data breaches and unauthorized access to user information.

How To Fix

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

pip uninstall dzuseragents

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