Description
The npm package @years17/n8n-nodes-utils-helper-c version 1.0.0 contains malicious code that performs host reconnaissance and data exfiltration. It registers a postinstall script that collects system information and environment details, encodes this data, and sends it to a remote server with TLS verification disabled. Additionally, a declared utility node executes shell commands to enumerate the host and returns raw output to workflows, without disclosing this behavior in its name or description.
