    ATT&CK tactics: Credential Access (TA0006)
    ATT&CK techniques: 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 Federation Services Analytics
    Attacker's goals: An attacker wanting to perform a golden SAML attack will want to steal the ADFS token-signing certificates. To steal the token-signing certificates, the attacker will need to access the ADFS database To access the encrypted ADFS database, an attacker will attempt to retrieve the decryption key via an LDAP query.
    Investigative actions: Check if the LDAP search query was allowed for the user (logged on at event time) or process. Check for unusual ADFS logins. Check the process that initiated the query. Investigate the LDAP search query for any suspicious indicators.
