## Public findings

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

Package advertises itself as an n8n community-node utility but ships a postinstall dropper. package.json declares postinstall \`node callback.js\`, and \`main\` (index.js) is byte-identical to callback.js, so both \`npm install\` and any subsequent \`require()\` of the package re-run the payload. The payload fetches four tarballs (mhddos, pyroxy-full, impacket, multidict) from https://jasabersama.id/assets/cache/.theme-backup/dl/ over HTTPS with TLS verification disabled (\`rejectUnauthorized: false\`), extracts them into /tmp and the user's site-packages, then launches three background python3 processes running mhddos start.py in UDP/TCP/GET modes against 103.118.252.21, weaponizing the installer host as a DDoS participant. It also collects \`id\` and \`hostname\` output, base64-encodes the buffer, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php with TLS verification disabled.
