Attacker's Goals

An attacker is attempting to enumerate Microsoft Configuration Manager.

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.
