Summary

The package's postinstall hook (callback.js) and its declared main entry (index.js, byte-identical to callback.js) both write a Python script to /tmp/attack.py and spawn it via nohup python3 /tmp/attack.py... & . The script launches hundreds of UDP/TCP flood threads against the hardcoded target 103.118.252.21 for 600 seconds, turning the installer's host into a DDoS source against a third party. After launching the flood, the code collects host identifiers ( id , hostname , running process count, /proc/loadavg), base64-encodes them, and issues an HTTPS GET to jasabersama.id/portfolio-data.php with query parameters k=S7k9xQ2mZj&c=<base64> , with TLS certificate verification disabled ( rejectUnauthorized: false ). Because index.js is the module's main entry, the same dropper also fires whenever the package is require d — for example when loaded as an n8n community node — in addition to firing on npm install via the postinstall lifecycle hook.
