Description
The qzc690384 package on PyPI contains malicious code that executes during installation by overriding the install command. It performs environment fingerprinting, exfiltrates basic system data such as IP address and username, and sets up a backdoor server to receive remote commands. The package downloads further commands from a hardcoded location and appears to prepare for additional stages of attack. This behavior is confirmed as part of a malicious campaign targeting users who install this package.
