Potential Active Directory Reconnaissance/Enumeration Via LDAP
Detects potential Active Directory enumeration via LDAP. This rule identifies suspicious LDAP search filters and distinguished name enumerations that are commonly used by reconnaissance tools like PowerView and SharpHound to gather information about users, groups, computers, and domain trusts within an Active Directory environment. The rule specifically looks for various 'groupType', 'sAMAccountType', 'objectCategory', 'objectClass', 'primaryGroupID', 'userAccountControl' attributes, and specific distinguished names or flags that indicate detailed AD reconnaissance.
