@years19/n8n-nodes-utils-helper-f @1.0.0

Summary

The package's postinstall (scripts.postinstall: node callback.js) collects host identity and environment fingerprint (output of id , hostname, Python user-site path with its contents filtered for offensive-tooling keywords such as pyroxy/impacket/multidict/socks/maxmind, presence of /tmp/mhddos and /tmp/implant, uptime), base64-encodes the result, and sends it as a query string to https://jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized: false). The request path also includes a hardcoded key k=S7k9xQ2mZj and a c= parameter carrying echo <b64> | base64 -d >> /tmp/n8n_rce_result.txt , matching a beacon/check-in shape for an attacker-controlled command channel. The package poses as an n8n community node (nodes/PwnNode.node.js exports only a stub description) while main (index.js) is identical to the postinstall exfil script, so both npm install and any require of the package trigger the beacon. The name mimics legitimate n8n-nodes-* community naming.
