What it detects

This rule detects nltest.exe enumerating domain trust relationships. UAT-5647 ran nltest domain_trusts to map Active Directory trusts during reconnaissance in the RomCom intrusions. Nltest domain trust enumeration is a common domain-discovery action attackers use to plan lateral movement across trusted domains.
