Description
The npm package 'luluking' version 0.0.1 contains malicious code that executes during installation. Its postinstall script reconstructs and executes a shell command to download and run a remote script from an attacker-controlled URL, enabling arbitrary code execution on the installer's machine. The malicious behavior is obfuscated using character code arrays to hide the URL and command from casual inspection.
