The npm package @years18/n8n-nodes-utils-helper-e version 1.0.0 contains malicious code that executes during installation and runtime. It runs a postinstall script that downloads and installs Python's pip, then launches a Python-based DDoS toolkit. The package also probes an internal network address and exfiltrates system identity information encoded in base64 to a remote server via an unverified TLS connection. The remote server can send shell commands back to the infected system, enabling remote code execution. The package masquerades as a helper utility for n8n but functions solely as a dropper and command-and-control relay.
