package.json declares a postinstall lifecycle script that runs node -e code opening a TCP connection to 185.112.147.174:7007 and piping the socket to a spawned /bin/sh, giving the operator of that endpoint an interactive shell on the installer's machine. The package ships no other functionality — its sole effect on install is to establish this reverse shell. Any developer workstation or CI job running npm install paperclip2 is compromised with arbitrary code execution as the invoking user.
