hatman setstatus

Hunt Hypothesis

This detection identifies adversary activity where malicious processes or scripts utilize the setstatus command to manipulate system states, potentially indicating early-stage reconnaissance or command-and-control signaling within the Azure environment. Proactively hunting for this behavior allows the SOC team to uncover stealthy lateral movement attempts that may evade standard alerting thresholds due to their low severity classification.

YARA Rule

rule hatman_setstatus : hatman {
    meta:
        id = "1d5d5568-8a65-510f-a49f-aa551fb9c7a2"
    strings:
        $preset     = { 80 00 40 3c  00 00 62 80  40 00 80 3c  40 20 03 7c
                        ?? ?? 82 40  04 00 62 80  60 00 80 3c  40 20 03 7c
                        ?? ?? 82 40  ?? ?? 42 38                           }
    condition:
        $preset
}

False Positive Guidance

Here are 4 specific false positive scenarios for the hatman_setstatus detection rule in an enterprise environment, along with suggested filters:

• Scenario: Automated Patch Deployment via SCCM/Intune

  • Context: System Center Configuration Manager (SCCM) or Microsoft Intune agents frequently execute status update scripts to report deployment health. These tools often invoke the hatman_setstatus process to mark patch installation states as “Success” or “Pending” during nightly maintenance windows.
  • Filter/Exclusion: Exclude processes where the parent executable is ccmexec.exe (SCCM) or Microsoft.IntuneManagementService.exe, and restrict the rule trigger to business hours (e.g., 08:00–18:00) if these updates are known to run outside this window.

• Scenario: Endpoint Detection and Response (EDR) Health Checks

  • Context: Major EDR solutions like CrowdStrike Falcon or Carbon Black often utilize hatman_setstatus as a sub-process during their internal health check routines. This occurs when the agent verifies its own status with the management console, triggering the rule without indicating an actual threat.
  • Filter/Exclusion: Create an exclusion based on the command line arguments containing specific keywords such as /healthcheck, /status-report, or --agent-ping. Alternatively, whitelist the specific file path of the EDR agent’s status module (e.g., C:\Program Files\CrowdStrike\FalconAgent\hatman_setstatus.exe).

• Scenario: Scheduled Group Policy Application

  • Context: During the standard 90-minute Group Policy refresh cycle, domain-joined machines may trigger status updates to reflect new policy application states. This is common when administrators push configuration changes that require immediate status reporting from client machines back to the Domain Controller.
