What is WinpkFilter LightWeight Filter Windows Driver?

WinpkFilter LightWeight Filter is a Windows kernel-mode driver that provides network packet filtering capabilities. It is part of the WinpkFilter software, which is designed to allow users to capture, analyze, and filter network traffic on a Windows-based machine. This driver is typically used by network monitoring applications, intrusion detection systems (IDS), or custom applications that need to intercept or filter network packets at the kernel level.

The "LightWeight Filter" refers to a lighter, more efficient version of the original WinpkFilter driver, focusing on providing basic packet capture and filtering without some of the more complex features found in the full version.
