ProActivateV10XTurboPowerSoftwareCompany

Hunt Hypothesis

This detection identifies the execution of the specific software artifact “ProActivateV10XTurboPowerSoftwareCompany,” which may indicate legitimate administrative activity or a potential supply chain compromise involving this vendor’s tools. A proactive hunt is essential to validate whether these executions align with known inventory and user behavior, ensuring that low-severity signals do not mask early-stage adversary presence within the Azure Sentinel environment.

False Positive Guidance

Here are 4 specific false positive scenarios for the ProActivateV10XTurboPowerSoftwareCompany detection rule, along with recommended filters and exclusions:

• Scenario: Scheduled License Renewal via Microsoft Task Scheduler

  • Context: The ProActivate V10 Turbo Power suite includes a built-in license manager that runs nightly to validate tokens. In an enterprise environment, this is often configured as a Windows Scheduled Task (ProActivate_LicenseCheck) running under the SYSTEM or a dedicated service account (e.g., svc-licensing).
  • Trigger: The YARA rule matches the executable hash of the renewal utility when it launches at 02:00 AM, flagging it as a new software installation event.
  • Filter/Exclusion: Exclude processes where the parent process is TaskScheduler.exe (PID 4) and the file path contains \Program Files\TurboPower\ProActivateV10\bin\LicenseManager.exe.

• Scenario: Endpoint Protection Scanning of Application Directory

  • Context: Enterprise antivirus solutions like CrowdStrike Falcon or Microsoft Defender for Endpoint perform periodic deep scans of application directories. When the scanner traverses the ProActivate installation folder, it may spawn a child process to analyze the core engine files.
  • Trigger: The YARA rule detects the scanning activity on the ProActivateV10XTurboPowerSoftwareCompany.dll or .exe as an active execution event rather than a passive scan artifact.
  • Filter/Exclusion: Create a file path exclusion for the entire installation directory: C:\Program Files\TurboPower\ProActivateV10\*. Additionally, filter out events where the parent process name is MsMpEng.exe (Defender) or FalconSensor.exe (Crowd
