Persistence via WMI Event Subscription
editPersistence via WMI Event Subscription
editAn adversary can use Windows Management Instrumentation (WMI) to install event filters, providers, consumers, and bindings that execute code when a defined event occurs. Adversaries may use the capabilities of WMI to subscribe to an event and execute arbitrary code when that event occurs, providing persistence on a system.

Investigation guide
edit## Setup If enabling an EQL rule on a non-elastic-agent index (such as beats) for versions <8.2, events will not define `event.ingested` and default fallback for EQL rules was not added until 8.2, so you will need to add a custom pipeline to populate `event.ingested` to @timestamp for this rule to work.
Rule query
editprocess where event.type in ("start", "process_started") and
(process.name : "wmic.exe" or process.pe.original_file_name == "wmic.exe") and
process.args : "create" and
process.args : ("ActiveScriptEventConsumer", "CommandLineEventConsumer")
