What it detects
This rule flags successful Windows logons (EventID 4624, LogonType 3) where the process name ends with scrcons.exe, excluding the specified Local System TargetLogonId. Activity involving Remote WMI ActiveScriptEventConsumers can be used by attackers to establish execution paths that support lateral movement and persistence. The detection relies on Windows Security audit telemetry for process-associated logon events and correlates the scrcons.exe logon context for further enrichment.
