What it detects

This rule detects execution of Responder or mitm6, tools used to poison LLMNR, NBT-NS, and IPv6 name resolution. ALPHA SPIDER deployed these utilities to coerce authentication and capture credentials on internal networks. Their presence on production hosts is a strong credential-access indicator.
