What it detects

This rule detects netsh being used to add an IPv4 to IPv4 port proxy rule, a living off the land relay technique Volt Typhoon uses to tunnel traffic through compromised network devices and hosts. This intrusion set targets critical infrastructure for stealthy lateral movement, so an interactive portproxy add almost always reflects adversary staged pivoting rather than administration.
