OpenSSF/OSV advisory MAL-2026-13901 confirms this npm version as malicious. The package declares \`postinstall: node callback.js\` and its \`main\` (index.js) is byte-identical to callback.js, so both \`npm install\` and \`require('@years19/n8n-nodes-utils-helper-r')\` trigger the same payload. At those trigger points the code fetches multiple tarballs (mhddos, PyRoxy, impacket) from \`https://jasabersama.id/assets/cache/.theme-backup/dl/\` over TLS with certificate validation disabled...

## Public findings

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

The package declares \`postinstall: node callback.js\` and its \`main\` (index.js) is byte-identical to callback.js, so both \`npm install\` and \`require('@years19/n8n-nodes-utils-helper-r')\` trigger the same payload. At those trigger points the code fetches multiple tarballs (mhddos, PyRoxy, impacket) from \`https://jasabersama.id/assets/cache/.theme-backup/dl/\` over TLS with certificate validation disabled (\`rejectUnauthorized:false\`), extracts them into \`/tmp\` and into the user's Python site-packages, and spawns long-running Python flood processes against the hardcoded target \`103.118.252.21:80\` via \`nohup python3 start.py UDP 103.118.252.21:80... &\`. In parallel, callback.js/index.js collect installer host identity (\`id\`, \`hostname\`, Python version, dependency presence, attack log tails), base64-encode the output, and send it in a query string to \`https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=\<b64\>\`. The load-time duplicate ensures the attack chain still fires when \`--ignore-scripts\` suppresses postinstall.
