the Nmap Project's packet sniffing library for Windows - Npcap

Npcap is an update of WinPcap to NDIS 6 Light-Weight Filter (LWF) technique. It supports Windows Vista, 7, 8 and 10 . It is sponsored by the Nmap Project and developed by Yang Luo under Google Summer of Code 2013 and 2015 . It also received many helpful tests from Wireshark and NetScanTools .

Features

1. NDIS 6 Support : Npcap makes use of new NDIS 6 Light-Weight Filter (LWF) API in Windows Vista and later (the legacy driver is used on XP). It's faster than the deprecated NDIS 5 API, which Microsoft could remove at any time.
2. Extra Security : Npcap can 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.
3. WinPcap Compatibility : If you choose WinPcap Compatible Mode at install-time, Npcap will use the WinPcap-style DLL directories c:\Windows\System32 and servcie name npf , allowing software built with WinPcap in mind to transparently use Npcap instead. If compatability mode is not selected, Npcap is installed in a different location C:\Windows\System32\Npcap with a different service name npcap so that both drivers can coexist on the same system. In this case, applications which only know about WinPcap will continue using that, while other applications can choose to use the newer and faster Npcap driver instead.
4. Loopback Packet Capture : Npcap is able to sniff loopback packets (transmissions between services on the same machine) by using the Windows Filtering Platform (WFP) . After installation, Npcap will create an adapter named Npcap Loopback Adapter for you. If you are a Wireshark user, choose this adapter to capture, you will see all loopback traffic the same way as other non-loopback adapters. Try it by typing in commands like ping 127.0.0.1 (IPv4) or ping ::1 (IPv6).
5. Loopback Packet Injection : Npcap is also able to send loopback packets using the Winsock Kernel (WSK) technique. User-level software such as Nping can just send the packets out using Npcap Loopback Adapter just like any other adapter. Npcap then does the magic of removing the packet's Ethernet header and injecting the payload into the Windows TCP/IP stack.
6. Raw 802.11 Packet Capture : Npcap is able to see 802.11 packets instead of fake Ethernet packets on ordinary wireless adapters. You need to select the Support raw 802.11 traffic (and monitor mode) for wireless adapters option in the installation wizard to enable this feature. When your adapter is in Monitor Mode , Npcap will supply all 802.11 data + control + management packets with radiotap headers. When your adapter is in Managed Mode , Npcap will only supply 802.11 data packets with radiotap headers. Moreover, Npcap provides the WlanHelper.exe tool to help you switch to Monitor Mode on Windows. See more details about this feature in section For softwares that use Npcap raw 802.11 feature .

Monitor APs and Wifi clients on selected channel (Monitor Mode) for Window - WifiChannelMonitor

WifiChannelMonitor is a utility for Windows that captures wifi traffic on the channel you choose, using Microsoft Network Monitor capture driver in monitor mode, and displays extensive information about access points and the wifi clients connected to them. WifiChannelMonitor also allows you to view the information about wifi clients that are not connected to any access points, including the list of SSIDs (network names) that they are trying to connect.

For every access point, the following information is displayed: SSID, MAC Address, Device Manufacturer , PHY Type, Channel, RSSI, Security, Beacons Count, Probe Responses Count, Data Bytes, Retransmitted Data Bytes, and more...

For every client, the following information is displayed: MAC Address, Device Manufacturer, SSID list that the client tries to connect, Sent Data Bytes, Received Data Bytes, Probe Requests Count, and more...

System Requirements

• Windows 10/Vista/7/8/2012 - 32-bit or 64-bit. (In previous version of Windows , there is no support for wifi monitor mode)
• Microsoft Network Monitor 3.x - You can download and install it from this Web page or from this Web page .
• Wireless network adapter and a driver that works properly in 'monitor mode' under Windows. See the remarks about that in the 'Known Problems' section below, it's very important !!

You can also use WifiChannelMonitor to watch wifi information offline by importing a capture pcap file created under Linux with airodump-ng or wireshark. In this case, there is no need for capture driver and you can also use it under Windows XP.

WifiChannelMonitor vs Other Tools

Capturing data using monitor mode allows WifiChannelMonitor to show information that other wifi tools cannot get:

• Detect and show all wifi clients (Tablets, Smartphones, computers with wifi adapter, and so on... ), Including wifi clients that are not connected to any access point, but only tries to connect...
• For wifi clients that try to connect to one or more APs - WifiChannelMonitor displays the list of network names (SSIDs) that the wifi client tries to connect.
• WifiChannelMonitor can also detect clients with a wired connection to the router.
• WifiChannelMonitor shows the number of sent/received data bytes for every access point and for every wifi client connected to the access point.
• WifiChannelMonitor can show the name of hidden network. (The name is detected only when somebody connects this wireless network)

Start Using WifiChannelMonitor

Before you start capturing wifi data with WifiChannelMonitor, you have to install the Microsoft Network Monitor 3.x from this Web page or from this Web page. Except of the Microsoft Network Monitor driver, there is no need for any installation process or additional dll files.

In order to start using WifiChannelMonitor, simply run the executable file - WifiChannelMonitor.exe

After running WifiChannelMonitor, press F6 to start capturing in wifi monitor mode. On the 'Capture Options' window, you have to choose the correct wireless network adapter and the channel number you want to monitor. It's recommended to start monitoring with one of the 3 major wifi channels - 1, 6, or 11.

After choosing the channel and adapter, click the Ok button to start monitoring. After a few seconds, you should see the access points information in the upper pane. If you don't see any information , stop the capture (F7) , go to the 'Capture Options' window (F9) and try to change from 802.11n to 802.11g. After that press F6 to start the capture again.

Wifi Clients Modes (Lower Pane)

There are 3 different modes that you can view the wifi clients in the lower pane:

• Show Clients Of Selected AP:In this mode, WifiChannelMonitor only displays the wifi clients that are connected to the access point you select in the upper pane.
• Show All Clients:In this mode, WifiChannelMonitor displays all detected clients.
• Show All Clients Without AP:In this mode, WifiChannelMonitor displays all clients that are not connected to any access point.
• Show All Clients With AP:In this mode, WifiChannelMonitor displays all clients that are connected to access point.
• Show Only Clients+APs In My List:In this mode, WifiChannelMonitor displays only the clients and APs that appear in the MAC Addresses List (Ctrl+F8)
