  • 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.

  • Uncommon access to /etc/passwd Informational 11 variations

    A process made an uncommon attempt to access /etc/passwd.

    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) System Service Discovery (T1007) System Owner/User Discovery (T1033) System Information Discovery (T1082) Account Discovery (T1087) Account Discovery: Local Account (T1087.001) OS Credential Dumping (T1003)
    Required data: XDR Agent with eXtended Threat Hunting (XTH)
    Detector tags: EDR Discovery Analytics, Credentials Grabbing Analytics
    Attacker's goals: Attackers may attempt to access sensitive files to steal credentials, perform reconnaissance on system configurations and users, and find pathways for lateral movement.
    Investigative actions: Review the event's context - examine the process, its command line, and its origin to gain a comprehensive understanding of the anomalous access. Assess the behavior's legitimacy: Given that this is an uncommon event, determine if this file access is an expected and authorized behavior for the actor process.
