Description
The npm package @years20/n8n-nodes-utils-helper-c version 1.0.0 contains malicious code that executes during installation. It collects system information and an SSH public key, then exfiltrates this data to an attacker-controlled server with TLS verification disabled. The package also deploys an embedded private SSH key to attempt unauthorized SSH access to localhost on common ports, enabling remote code execution and lateral movement on the host system. This malicious behavior is disguised as a helper utility for n8n.
