## What is MAL-2026-13905?

MAL-2026-13905 is a malicious package in @years19/n8n-nodes-utils-helper-v, published on 12 Aug 2026. 

### Official description

The package's postinstall hook runs `node callback.js`, and package.json declares `main: index.js` with byte-identical contents, so the payload fires on both `npm install` and `require()`/import. On execution the code writes a Python UDP/TCP flood script to /tmp/attack.py and launches it via `nohup python3 /tmp/attack.py &`, directing ~650 threads at 103.118.252.21 on ports 80/443 for 600 seconds. In parallel, the code runs `id` and `hostname`, collects process/loadavg indicators, base64-encodes the result, and sends it via `https.get` with `rejectUnauthorized: false` to `https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=<encoded>`. Installer hosts become participants in an outbound DDoS attack while also leaking host identity to a hardcoded endpoint.

## What should I do about MAL-2026-13905?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
