What it detects

This rule detects AdFind querying domain trust attributes through the trustdmp shortcut which the OneNote intrusion used to map trust relationships for onward movement and this matters because the trustdmp query is specific to attacker reconnaissance of domain trusts and has no routine administrative use.
