Remote Management and Monitoring tool - MSP360_CloudBerry - Create Process

Hunt Hypothesis

The hypothesis is that an adversary is using the MSP360_CloudBerry tool to create processes for persistence or establish command and control channels. SOC teams should proactively hunt for this behavior in Azure Sentinel to identify potential compromise of remote endpoints managed by RMM tools.

False Positive Guidance

• Scenario: Legitimate Scheduled Job Execution
  Description: A system administrator schedules a job using MSP360 or CloudBerry to back up files or perform routine maintenance.
  Filter/Exclusion: process.parent_process_name == "schtasks.exe" or process.command_line contains "schtasks /create"

• Scenario: Admin Task for Remote System Management
  Description: An IT admin uses MSP360 to remotely manage a workstation, such as deploying software updates or configuring settings.
  Filter/Exclusion: process.parent_process_name == "mspsvc.exe" or process.command_line contains "mspsvc"

• Scenario: CloudBerry Backup Process Running Normally
  Description: CloudBerry is configured to run backup jobs on a schedule, which involves creating processes to interact with remote systems.
  Filter/Exclusion: process.command_line contains "CloudBerryBackup.exe" or process.name == "CloudBerryBackup.exe"

• Scenario: Remote PowerShell Session for Management
  Description: An admin uses PowerShell remoting via MSP360 to execute commands on a remote endpoint, which may trigger process creation.
  Filter/Exclusion: process.parent_process_name == "powershell.exe" and process.command_line contains "Invoke-Command"

• Scenario: System Update or Patch Deployment
  Description: A patching tool or update manager (e.g., SCCM, WSUS) uses MSP360 or CloudBerry to deploy updates, which may involve process creation.
  Filter/Exclusion: process.command_line contains "wsusutil.exe" or process.command_line contains "setup.exe"
