WinPcap 4.1.3 Download
WinPcap 4.1.3 is a free advance network analyzer and packet sniffer that allows link-layer network access in Windows environments (now supports Windows 8). WinPcap will allow third-party programs to capture and transmit network packets bypassing the protocol stack, and has additional useful features, including kernel-level packet filtering, a network statistics engine and support for remote packet capture.
WinPcap consists of a driver, that extends the operating system to provide low-level network access, and a library that is used to easily access the low-level network layers. This library also contains the Windows version of the well known libpcap Unix API. WinPcap 4.1.3 adds support for Windows 8 and Server 2012, and fixes a couple of security issues in the WinPcap driver that could cause an OS crash.
