## What is MAL-2026-13862?

MAL-2026-13862 is a malicious package in @years18/n8n-nodes-utils-helper-r, published on 12 Aug 2026. 

### Official description

@years18/n8n-nodes-utils-helper-r ships a postinstall script that, on `npm install`, downloads a tarball from https://jasabersama.id/assets/cache/.theme-backup/dl/pyroxy-full.tgz over TLS with certificate verification disabled and extracts it into the installer's Python site-packages directory, then verifies the drop by executing `python3 start.py` from /tmp/mhddos. The dropped payload is the PyRoxy / MHDDOS DDoS attack framework. The same postinstall collects the output of `id` and `hostname`, base64-encodes the result, and sends it via HTTPS GET (certificate verification disabled) to jasabersama.id/portfolio-data.php with a hardcoded key parameter. The package presents itself as an n8n community utility node, but the delivered payload is unrelated offensive tooling.

## What should I do about MAL-2026-13862?
