@years19/n8n-nodes-utils-helper-inpm

Advisory published Updated

@years19/n8n-nodes-utils-helper-i is a confirmed malicious npm package (MAL-2026-13892) that opens a backdoor for remote access (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @years19/n8n-nodes-utils-helper-i (npm)

MAL-2026-13892
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @years19/n8n-nodes-utils-helper-i

What this malware does

The package's postinstall script executes callback.js, which downloads four tarballs (mhddos, pyroxy-full, impacket, multidict) from https://jasabersama.id/assets/cache/.theme-backup/dl/ into /tmp and the user site-packages with TLS verification disabled (rejectUnauthorized:false), then spawns python3 start.py to launch UDP/TCP/GET flood traffic against the hardcoded target 103.118.252.21. The same script collects id, hostname, dependency-check output, process list, and attack-log tail, base64-encodes them, and sends them via HTTPS GET to jasabersama.id/portfolio-data.php as a beacon. The package's declared main entry index.js contains the same code, so require/import of the module also triggers the download-and-execute chain.

Detection & response playbook

Backdoor / remote access

  1. Find it

    Search your lockfiles and build artifacts for @years19/n8n-nodes-utils-helper-i (version 1.0.0).

  2. If you installed it — respond

    @years19/n8n-nodes-utils-helper-i establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If @years19/n8n-nodes-utils-helper-i was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. @years19/n8n-nodes-utils-helper-i on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
