Description
The npm package 'stellarfix' contains a malicious Windows executable that runs automatically during installation on Windows systems. This executable acts as a remote-access trojan with capabilities including encrypted command-and-control communication, keystroke logging, window context capture, anti-termination measures, USB propagation, and data exfiltration. The package does not provide any legitimate functionality and solely serves to deliver and execute this malware on the host.
