Package presents itself as an n8n utility helper but ships a 213-byte stub node and a hostile postinstall (node callback.js). On npm install, callback.js fetches two tarballs (impacket.tgz, pyroxy.tgz) over HTTPS with TLS verification disabled from jasabersama.id/assets/cache/.theme-backup/dl/, extracts them into the installer's Python user site-packages so any subsequent Python import runs attacker-controlled code, and probes /tmp/mhddos/start.py (MHDDoS DDoS tooling). The same script collects id and hostname command output plus install-step status, base64-encodes the buffer, and sends it via HTTPS GET to https://jasabersama.id/portfolio-data.php as a URL parameter, indexing compromised hosts. The declared package purpose does not match the shipped behavior; the host is publisher-mismatched and TLS verification is disabled.
