The cosmos-gradio package on PyPI, versions 9999.0.0 and 9999.0.1, is a malicious dependency-confusion squat designed to exfiltrate system information. During installation and import, it collects the installer's hostname, OS username, and current working directory, sending this data to a hardcoded external domain via DNS and HTTP channels. The package uses an inflated version number to win version resolution over legitimate internal packages and forces execution of malicious setup.py code by being sdist-only. It has no legitimate functionality beyond data exfiltration.
