@years20/n8n-nodes-utils-helper-g@1.0.0

Summary

On npm install, the package's postinstall script (duplicated in the main module) executes shell commands to collect host identity (id, hostname, pwd), locates n8n installation directories, enumerates running n8n processes, and reads n8n-related environment variables. The collected output is base64-encoded and sent via HTTPS GET to the hardcoded endpoint https://jasabersama.id/portfolio-data.php with TLS certificate validation disabled (rejectUnauthorized: false). The request includes a static key parameter k=S7k9xQ2mZj and a c= parameter containing a shell command payload (echo <base64> | base64 -d >> /tmp/n8n_rce_result.txt), and the endpoint filename plus payload shape indicate an RCE staging harness. The package's advertised utility helper purpose is a cover; the only substantive content is the install-time recon and beacon.
