description: This rule matches Windows process creation events where the process metadata indicates ScreenConnect, including a ScreenConnect service and related product/company strings. Attackers may use remote access tools like ScreenConnect to establish interactive connectivity for command and control while blending in with legitimate software. Telemetry relied on is process creation data on Windows, specifically fields containing Description, Product, and Company identifying ScreenConnect.
