    Required data: XDR Agent with eXtended Threat Hunting (XTH)
    Detector tags: LDAP Analytics (Server)
    Attacker's goals: An adversary may utilize the LDAP protocol to gain information on the Active Directory environment and plan its lateral movement over the network.
    Investigative actions: Where possible, check the legitimacy of the process that executed these LDAP queries. Investigate the LDAP search query for any suspicious indicators. Determine whether the search query is generic, those search queries (often using wildcards) tend to be more suspicious.
