  • A suspicious process queried AD CS objects via LDAP Informational Identity Analytics 1 variation

    A suspicious process queried AD CS objects via LDAP.

    Activation:
    14 Days
    Training:
    30 Days
    Test:
    N/A (single event)
    Deduplication:
    1 Day
    ATT&CK tactics: Discovery (TA0007) Credential Access (TA0006)
    ATT&CK techniques: File and Directory Discovery (T1083) Steal or Forge Authentication Certificates (T1649)
    Required data: XDR Agent with eXtended Threat Hunting (XTH)
    Detector tags: LDAP Analytics (Client), Active Directory Certificate Services Analytics
    Attacker's goals: An attacker might look for AD CS servers, certificate templates or request certificates. With the wrong setting or loose vulnerable templates or enabled enrollment, the attacker will be able to authenticate as users on the network.
    Investigative actions: Check if the LDAP search query was allowed for the user (logged on at event time) or process. Investigate the LDAP search query for any suspicious indicators.

    Low overridden

    A user enumerated AD CS objects using suspicious LDAP query. overridden

  • LDAP AD CS Enumeration via Attack Tool Low Identity Analytics 1 variation

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

    Activation:
    14 Days
    Training:
    30 Days
    Test:
    N/A (single event)
    Deduplication:
    1 Day
    ATT&CK tactics: Discovery (TA0007) Credential Access (TA0006)
    ATT&CK techniques: Account Discovery (T1087) Steal or Forge Authentication Certificates (T1649)
    Required data: XDR Agent with eXtended Threat Hunting (XTH)
    Detector tags: LDAP Analytics (Client), LDAP Analytics (Server), Active Directory Certificate Services Analytics
    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.
