## Public findings

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

The package presents itself as an n8n community node (\`n8n-nodes-utils-helper-d\`) but its actual on-install behavior is unrelated to workflow automation. The postinstall script fetches a tarball from \`https://jasabersama.id/assets/cache/.theme-backup/dl/multidict.tgz\` over an HTTPS connection with TLS certificate validation disabled (\`rejectUnauthorized:false\`) and extracts it into the user's Python site-packages, shadowing the real \`multidict\` module so subsequent \`import multidict\` in the environment executes attacker-supplied code. Follow-up shell activity references PyRoxy/impacket and \`/tmp/mhddos/start.py\`, consistent with a DDoS / offensive-tooling dropper. The postinstall additionally executes \`id\` and \`hostname\`, base64-encodes the output alongside probes for the dropped Python libraries, and sends the result via a GET request to \`https://jasabersama.id/portfolio-data.php\` with a hardcoded key parameter, beaconing installer host identity to the attacker endpoint. The shipped node file is a stub named \`PwnNode.node.js\`, and no legitimate n8n node functionality is present.
