Description
A user sent a suspicious enumeration query via LDAP. The query is associated with an LDAP enumeration tool that may be used during attacks against the organization.
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.
