Targeted DCSync
When performing targeted DCSync (e. g., for persistence purposes) choose the most valuable accounts. One can use the following LDAP query to search for effective domain admins (adminCount=1) as well as DC computer accounts (SERVER_TRUST_ACCOUNT bit or userAccountControl=8192 is set):
(&
	(|
		(&(objectCategory=person)(objectClass=user))
		(&(objectCategory=computer)(objectClass=computer))
	)
	(!(userAccountControl:1.2.840.113556.1.4.803:=2))
	(|
		(adminCount=1)
		(userAccountControl:1.2.840.113556.1.4.803:=8192)
	)
)
