Domain Trust Discovery
Where this stands
One published detection covers this technique. Every one is unverified — no rule on Siemphony has been executed against real telemetry.
What the technique is
Adversaries may attempt to gather information on domain trust relationships that may be used to identify lateral movement opportunities in Windows multi-domain/forest environments. Domain trusts provide a mechanism for a domain to allow access to resources based on the authentication procedures of another domain. Domain trusts allow the users of the trusted domain to access resources in the trusting domain. The information discovered may help the adversary conduct SID-History Injection, Pass the Ticket, and Kerberoasting. Domain trusts can be enumerated using the DSEnumerateDomainTrusts() Win32 API call,.NET methods, and LDAP. The Windows utility Nltest is known to be used by adversaries to enumerate domain trusts.

Adversary uses nltest, PowerShell, or Win32/.NET API to enumerate domain trust relationships (via DSEnumerateDomainTrusts, GetAllTrustRelationships, or LDAP queries), followed by discovery or authentication staging.
