The package's preinstall lifecycle script (preinstall.js) opens a TCP socket to the hardcoded remote host 120.55.170.103:8888, spawns cmd.exe, and pipes the shell's stdio through the socket, giving the remote party full interactive command execution on the installer's machine during npm install. The same script also collects installer host identifiers (os.hostname(), os.userInfo().username, os.platform(), process.version, process.cwd()) while the reverse shell is connected. Cover-story strings in the file ("Proof of Concept", "Dependency Confusion") do not change the observed behavior: install-time remote code execution against the installer.
