The Microsoft WFP Message Capture Driver is a kernel-mode driver associated with the Windows Filtering Platform (WFP). It is primarily used for capturing network traffic at various layers of the Windows networking stack for analysis, troubleshooting, or debugging network-related issues. WFP allows developers and administrators to filter, inspect, and modify network traffic at different layers of the stack, including the link layer, network layer, and transport layer.
The Message Capture driver helps capture the packets as they traverse through the network stack, providing insights into how packets are processed, whether they are dropped, modified, or forwarded.
