    Required data: XDR Agent with eXtended Threat Hunting (XTH)
    Detector tags: Microsoft SCCM Analytics
    Attacker's goals: Attackers can retrieve plaintext domain credentials, which may be used for proxying tools into the environment over command and control (C2). If the credentials are overprivileged, this technique may enable lateral movement to other clients or sensitive systems. Determine whether this was a legitimate action.
    Investigative actions: Follow process, user, and host activities. Investigate if the retrieved credentials match any known accounts or if there is any abnormal access to distribution points or other critical resources. Verify the presence of unauthorized tools or processes like SharpDPAPI or SharpSCCM that could have been used for credential extraction or decryption. Review relevant system logs (event logs, SCCM logs, etc.) for any signs of unusual activity or access patterns related to the NAA or other credentials.
