  • DSC (Desired State Configuration) lateral movement using PowerShell Informational 3 variations

    An attacker is using the DSC feature with PowerShell to remotely modify / execute content / components on the machine.

    Activation:
    14 Days
    Training:
    30 Days
    Test:
    N/A (single event)
    Deduplication:
    1 Hour
    ATT&CK tactics: Lateral Movement (TA0008) Execution (TA0002)
    ATT&CK techniques: Windows Management Instrumentation (T1047) Remote Services: Windows Remote Management (T1021.006)
    Required data: XDR Agent with eXtended Threat Hunting (XTH)
    Attacker's goals: Execute malicious content on and move laterally across machine in the network.
    Investigative actions: Search for suspicious WinRM sessions and the user created them, can be found at Event ID: 4102. Additionally, search for the DSC resource executed and related IOC, can be found at Event IDs: 400 or 4104.

  • WmiPrvSe.exe Rare Child Command Line Low 1 variation

    A remote WMI command executed a binary proxy, the Windows Management Instrumentation (WMI) Provider Host wmiprvse.exe, which executed a rare child command line. Executing a rare child process can be an indication of remote code execution abuse by an attacker.
