On `pip install`, setup.py checks `/proc/version` for WSL markers and, when matched, opens a TCP socket to the hardcoded IP 185.184.192.205 on port 4444, sends a JSON beacon containing `os.getlogin()`, `os.uname().nodename`, and `os.getcwd()`, then spawns a background thread that reads JSON commands from the socket and executes them via `subprocess.run(cmd, shell=True, capture_output=True, text=True)`, returning stdout/stderr to the operator \u2014 full remote command execution against the installer\u0027s machine. setup.py also appends a Python one-liner to `~/.bashrc` that re-opens the same socket, `dup2`s stdio onto it, and execs `/bin/bash -i`, giving the attacker a persistent interactive reverse shell that fires on every new login shell and survives package uninstall. The WSL-only gating is a deliberate evasion to stay dormant on non-WSL maintainer machines and execute only on targeted Windows-Subsystem-for-Linux developer hosts.\n\n## Source: kam193 (bd626be82a68d95788077b8b3c87a960c87d971e55496791cedf85154d99087f)\nInstalling the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.\n\n\n---\n\nCategory: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research \u0026 co, with clearly low-harm possibilities.\n\n\nCampaign: GENERIC-standard-pypi-install-pentest\n\n\nReasons (based on the campaign):\n\n\n - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n",
