## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

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.
