Description

An unpopular and unsigned process performed an LDAP search query. This may be indicative of LDAP enumeration.

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. Generic search queries (often using wildcards) tend to be more suspicious.
