EDRChoker - WMI QoS Policy Manipulation
This rule detects attempts to manipulate Windows Management Instrumentation (WMI) Quality of Service (QoS) policies, specifically targeting the 'MSFT_NetQosPolicySettingData' class. This activity is indicative of the EDRChoker technique, which aims to throttle network traffic for Endpoint Detection and Response (EDR) agents to hinder their telemetry and block their functionality. The detection logic looks for WMI events or process command lines containing references to 'MSFT_NetQosPolicySettingData' along with 'ThrottleRateAction' or 'AppPathNameMatchCondition'.
