Description

The npm package @years19/n8n-nodes-utils-helper-k version 1.0.0 contains malicious code that executes during installation and import. It downloads multiple attacker-hosted tarballs containing DDoS tools, disables TLS verification during downloads, and executes a Python script to launch UDP/TCP/GET flood attacks against a specific IP address. Additionally, it collects and exfiltrates system identifiers to a command-and-control server. The package masquerades as a utility helper for n8n but provides no legitimate functionality.

Impact

This package enables attackers to conduct distributed denial-of-service (DDoS) attacks by using compromised hosts to flood a target IP with UDP, TCP, and GET requests. It also compromises host confidentiality by exfiltrating system identifiers to an attacker-controlled server. The automatic execution on installation and import increases the risk of widespread compromise in environments using this package.

Defensive guidance

Users should immediately remove and avoid installing or importing the @years19/n8n-nodes-utils-helper-k package version 1.0.0. Verify all dependencies for authenticity and consider scanning for indicators of compromise related to this package. Monitor network traffic for unusual outbound connections to jasabersama.id and the targeted IP 103.118.252.21.

Summary

The malicious npm package @years19/n8n-nodes-utils-helper-k version 1.0.0 includes a postinstall script and a main entry point that both trigger the same malicious behavior. This behavior involves fetching multiple tarballs from an attacker-controlled domain with TLS verification disabled, unpacking them into temporary and Python site-package directories, and executing a Python script that performs network flood attacks against IP 103.118.252.21. The package also collects the installer's system ID and hostname, encodes this information in base64, and sends it via an unverified TLS GET request to the attacker's server. These actions occur automatically on npm install and when the package is imported or required, including when loaded as an n8n community node. The package does not provide any legitimate utility functions and solely serves as a delivery mechanism for DDoS tools and host reconnaissance.
