GitHub - wireshark/winpcap: The WinPcap packet

DocsDownloadLicensingWindows 11WinPcapNpcap is the Nmap Project's packet capture (and sending) libraryfor Microsoft Windows. It implements theopen Pcap API using acustom Windows kernel driver alongside our Windows buildof the excellent libpcaplibrary. This allows Windows software to capture raw networktraffic (including wireless networks, wired ethernet, localhosttraffic, and many VPNs) using a simple, portable API. Npcapallows for sending raw packets as well. Mac and Linux systems alreadyinclude the Pcap API, so Npcap allows popular software suchas Nmapand Wireshark to run on allthese platforms (and more) with a single codebase. Npcap began in2013 as some improvements to the (now discontinued) WinPcap library,but has been largely rewritten since thenwith hundreds of releasesimproving Npcap's speed, portability, security, and efficiency. Inparticular, Npcap now offers: Loopback Packet Capture and Injection: Npcap is able to sniff loopback packets (transmissions between services on the same machine) by using the Windows Filtering Platform (WFP). After installation, Npcap supplies an interface named NPF_Loopback, with the description “Adapter for loopback capture”. Wireshark users can choose this adapter to capture all loopback traffic the same way as other non-loopback adapters. Packet injection works as well with the pcap_inject() function. Support for all Current Windows Releases: Npcap supports all versions of Windows and Windows Server thatMicrosoft themselves still support. To avoid limiting ourselves just to the features and API's of our oldest supportedWindows release, we build and ship drivers for each major platform generation. That way we can use all of Microsoft'slatest technology in our Win10 driver while still supporting legacy systems. Npcap works on Windows 7 and later bymaking use of the NDIS 6 Light-Weight Filter (LWF) API. It's faster than the deprecated NDIS 5 API used by WinPcap. Also, the driver is signed with our EV certificate and countersigned by Microsoft so that it works even with the stricter driver signing requirements imposed by Windows 10. We don't know exactly when Microsoft will remove NDIS 5 or cease the grandfathering of older less secure driver signatures, but WinPcap will cease working when that happens. Libpcap API: Npcap uses the excellent Libpcap library, enabling Windows applications to use a portable packet capturing API that is also supported on Linux and MacOS. While WinPcap was based on LibPcap 1.0.0 from 2009, Npcap includes the latest Libpcap release along with all of the improvements we contribute back upstream to them. Support for all Windows architectures (x86, x86-64, and ARM): Npcap has always supported both Windows 64-bit. As of now, WinPcap 4.1.2 is available in the download section of the WinPcap website, This release fixes a couple of bugs in the WinPcap WinPcap 4.1.3 adds support for Windows 8 and Server 2025, and fixes a couple of security issues in the WinPcap driver that could cause an OS crash.

And 32-bit Intel x86 platforms. But starting with version 1.50 we also support the new Windows on ARM architecture! This allows PC's to use the same power-efficient mobile chipsets as smartphones for all-day battery life and always-on LTE connectivity. Users can now run apps like Nmap and Wireshark on a new generation of devices like the Microsoft Surface Pro X tablet and the Samsung Galaxy Book Go laptop. Extra Security: Npcap can (optionally) be restricted so that only Administrators can sniff packets. If a non-Admin user tries to utilize Npcap through software such as Nmap or Wireshark, the user will have to pass a User Account Control (UAC) dialog to utilize the driver. This is conceptually similar to UNIX, where root access is generally required to capture packets. We've also enabled the Windows ASLR and DEP security features and signed the driver, DLLs, and executables to prevent tampering. WinPcap compatibility: Software written for WinPcap is generally source-code compatible with WinPcap so it simply needs to be recompiled with the Npcap SDK to receive all of Npcap's performance, compatability, and security benefits. In fact there is even some binary compatability—software compiled with the WinPcap SDK often still works with modern Npcap. We don't suggest relying on that, however, since compilers and other stack technology has changed dramatically since the last WinPcap SDK release in 2013. When porting legacy WinPcap software to Npcap, we do suggest a few minor changes, mostly to ensure your software uses Npcap in preference to WinPcap on systems with both libraries installed. By default Npcap replaces any old WinPcap software installs with its own drivers, but you can install both by unchecking Npcap's “WinPcap Compatible Mode.” installer option. Raw (monitor mode) 802.11 wireless capture: Npcap can be configured to read raw 802.11 traffic, including radiotap header details, and this functionality is directly supported by Wireshark. More details can be found here. Many more details about Npcap are available in the Npcap User/Developer Guide. We've also created a feature comparison between Npcap and WinPcap.The free version of Npcap may be used (but not externally redistributed) on up to 5 systems (free license details). It may also be used on unlimited systems where it is only used with Nmap, Wireshark, and/or Microsoft Defender for Identity. Simply run the executable installer. The full source code for each release is available, and developers can build their apps against the SDK. The

[Winpcap-users] Does WinPcap support IPv6?

How the Promiscuous Mode Scanner Tool works This tool actively scans your subnet with modified ARP packets and shows the devices responding to each type of ARP packets. The devices that respond to nearly every packet are most likely listening in Promiscuous Mode (ie. the ethernet interface is capturing IP packets not intended for that IP address). All IPv4 devices MUST respond to ARP even if they are running a firewall and invisible to normal ICMP Ping. Note that ARP is not routed so you are limited to your subnet. The image below shows a DSL router in the first row listening in Promiscuous Mode which would be expected from this type of device. Note that the scanner requires the use of WinPcap. We install WinPcap as part of the installation package. WinPcap is designed for wired ethernet cards, not cellular modems and it usually works well with 802.11x wireless interfaces..
