What is MAL-2026-13866?
MAL-2026-13866 is a malicious package in @years18/n8n-nodes-utils-helper-v, published on 12 Aug 2026.
Official description
The package masquerades as an n8n community node (name @years18/n8n-nodes-utils-helper-v, node file nodes/PwnNode.node.js with an empty 'x' description) while the real behavior is in a postinstall dropper. On npm install the postinstall script collects host identity (
id, hostname) via callback.js, base64-encodes the result, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php with TLS verification disabled (rejectUnauthorized:false). The same postinstall path installs the impacket network-attack library via pip install --break-system-packages, probes PyRoxy, and attempts to execute /tmp/mhddos/start.py (MHDDoS). Installing this package auto-runs reconnaissance, exfiltrates installer host identifiers to a hardcoded third-party endpoint, and stages offensive DDoS/network-attack tooling on the installer's machine.What should I do about MAL-2026-13866?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
