What it detects

This rule flags execution of Inveigh by matching process creation details for Inveigh.exe or its original file name, along with the Inveigh product description. It also requires command-line arguments commonly used for spoofing and traffic interception (e.g., SpooferIP and SnifferIP, plus ReplyTo* parameters). Such activity matters because Inveigh is used for IPv4/IPv6 MITM-style operations to capture or influence network credentials, and the rule relies on Windows process creation telemetry including Image path, original file name, description, and command line.
