Description
A possible GPO enumeration via LDAP was performed. Such enumeration may be used during attacks against the organization.
Attacker's Goals
An attacker is attempting to enumerate Active Directory.
Investigative actions
- Investigate the LDAP search query for any suspicious indicators.
- Look for additional LDAP queries the user executed that might be suspicious.
- 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.
- Check if the process executes LDAP search queries as part of its normal behavior.
