The npm package @years17/n8n-nodes-utils-helper-b version 1.0.0 contains malicious code that performs extensive credential harvesting and host reconnaissance. It collects sensitive information such as system identifiers, Docker socket state, sudo permissions, SSH authorized keys, environment variables with secrets, Kubernetes config, Google Cloud credentials, and crontab entries. This data is encoded and exfiltrated to a remote server with TLS verification disabled. Additionally, the package includes an n8n node that executes arbitrary system commands to gather further host information within the n8n runtime environment.
