In my previous blog post I covered how Microsoft has enhanced WMI logging in the latest versions of their client and server operating systems. WMI Permanent event logging was also added in version 6.10 specific events for logging permanent event actions. The new events are:
- Event ID 19: WmiEvent (WmiEventFilter activity detected). When a WMI event filter is registered, which is a method used by malware to execute, this event logs the WMI namespace, filter name and filter expression.
- Event ID 20: WmiEvent (WmiEventConsumer activity detected). This event logs the registration of WMI consumers, recording the consumer name, log, and destination.
- Event ID 21: WmiEvent (WmiEventConsumerToFilter activity detected). When a consumer binds to a filter, this event logs the consumer name and filter path
