description: "This search looks for the execution of `nltest.exe` with command-line arguments utilized to query for Domain Trust information.
Two arguments `/domain trusts`, returns a list of trusted domains, and `/all_trusts`, returns all trusted domains.
Red Teams and adversaries alike use NLTest.exe to enumerate the current domain to assist with further understanding where to pivot next."
description: This search looks for the execution of `nltest.exe` with command-line
arguments utilized to query for Domain Trust information. Two arguments `/domain
trusts`, returns a list of trusted domains, and `/all_trusts`, returns all trusted
domains. Red Teams and adversaries alike use NLTest.exe to enumerate the current
domain to assist with further understanding where to pivot next.
how_to_implement: To successfully implement this search you need to be ingesting information
on process that include the name of the process responsible for the changes from
your endpoints into the `Endpoint` datamodel in the `Processes` node.
