On npm install, the package's preinstall hook executes install.js, which collects host identifiers (os.hostname(), process.cwd(), username) and reads flag files from /flag, /flag.txt, /app/flag, /home/node/flag, and /tmp/flag, then PUTs the collected data to the hardcoded bare-IP endpoint http://154.57.164.66:39270/api/modules/* over plain HTTP. install.js is additionally wrapped as a PowerShell here-string (opening with @" and closing with "@ | Out-File -Encoding ascii install.js), structured as a polyglot that can rewrite itself on Windows before Node executes the exfiltration payload. The behavior fires automatically on default install and has no relationship to the package's stated color-utility purpose.
