Attacker's goals:

An attacker is attempting to enumerate Active Directory.

Investigative actions:

Check if the process executes LDAP search queries as part of its normal behavior. Investigate the LDAP search query for any suspicious indicators. Determine whether the search query is generic. Wide search queries (often using wildcards) tend to be more suspicious. In our case, we are looking for targeted search queries.
