Description

The npm package @years17/n8n-nodes-utils-helper-d version 1.0.0 contains malicious code that executes during installation and when required. It collects sensitive host information including directory listings, internal DNS names, and SSH authorized keys, encodes this data, and sends it to a remote server with TLS verification disabled. The package also supports remote command execution by receiving commands via a parameter and writing their output to a temporary file. This behavior indicates an active reconnaissance and credential theft campaign targeting installer environments.

Impact

This malicious package compromises the confidentiality and integrity of the host system by exfiltrating sensitive environment and credential data to an attacker-controlled server. It also enables remote command execution on the affected system, potentially allowing attackers to execute arbitrary commands with the privileges of the installer or runtime user. This can lead to further compromise of the host and connected infrastructure.

Defensive guidance

Users should avoid installing or using @years17/n8n-nodes-utils-helper-d version 1.0.0. Audit and remove this package if already installed. Monitor for suspicious network connections to jasabersama.id or similar domains. Use trusted sources and verify package authenticity before installation. Consider implementing supply chain security controls such as package integrity verification and restricting installation of untrusted packages.

Summary

The malicious npm package @years17/n8n-nodes-utils-helper-d (version 1.0.0) runs a postinstall script and code on require that executes a Node.js script using execSync to gather sensitive host environment data such as directory listings (/app, /opt, /home/ubuntu), process command lines, hosts files, internal DNS names (e.g., nexus.local), and SSH authorized keys. This data is base64-encoded and exfiltrated via an HTTPS GET request to jasabersama.id with TLS verification disabled (rejectUnauthorized: false). The request includes a parameter that decodes and executes shell commands, writing results to /tmp/n8n_rce_result.txt, enabling remote command execution. The package name mimics legitimate n8n community nodes utilities, suggesting a supply chain attack aimed at reconnaissance and credential theft within installer infrastructure.
