var q AircrackWindowsPacketMathy Vanhoef, Ph. D. Microsoft first added support for MAC address randomization in Windows 1. Unfortunately, its only available if you have a Wi. Fi card and driver that support it. For example, the Intel 7. AC, when using the latest driver, supports randomization 1. You can see if your hardware supports MAC address randomization by going through the following menus. If your hardware supports MAC address randomization, you will see the following option at the top of the window As you can see, I have it enabled on my laptop. So far its been working quite well. Whats very interesting about Microsofts approach is that it also uses random MAC addresses when connecting to a wireless networks. In contrast, Apple only uses random addresses when searching for nearby networks, and it falls back to its original address when connecting to a network. In this aspect Windows 1. Apple. Using a random MAC address to connect to a network can cause problems if users are authenticated i. MAC address 2. Interestingly, Windows avoids this issue by always using the same random address every time it. For example, lets say you want to pay for Wi Fi access, and they authenticate you based on your MAC address. Then this is not a problem. The first time you connect, Windows will generate a random MAC address. And if you reconnect to this network at a later point in time, Windows will reuse the previously generated address. Therefore the system can still recognize you, and you dont have to pay twice. Theres one downside to this approach since you always use the same address when connecting to a particular network, an adversary can learn when certain devices connect to specific networks. Nevertheless, compared to the old situation where youd always use the original MAC address, it improves your privacy. Technically, the random MAC address that is used to connect to a network is calculated as 5. SHA 2. 56SSID, real MAC address, connection. Id, secret 6. Here SSID is the name of the network you are connecting to, real MAC address the original address of your network interface, and connection. Id is a value that changes every time the user removes and re adds the network i. Windows 1. 0. The secret parameter is a 2. Every interface has a different value of the secret parameter, to assure each interface gets different random MAC address. Finally, bits in the most significant byte of address are set so it becomes a locally administered, unicast address. While the presentation by Huitema partly described this process, our paper is the first to describe this formula in full detail. Its also possible to disable randomization for certain networks. In this case Windows will use the original address when connecting to a network. You can configure this through the following settings when you are currently connected to the network. Aircrack Windows Packet CraftingNotice that the user has three options for each specific network On the same random MAC address is always used when connecting to this network. Off the original MAC address is used. Change daily every day a new random MAC address is used. Remark that if randomization is enabled, independent of the above options, Windows 1. MAC addresses when scanning for nearby networks. This scanning address changes every time you connect and disconnect from a network, and when you restart your device 3. Hence it doesnt change that frequently, but its still sufficient to prevent tracking over extended periods of time. In contrast, Apple changes the scanning address roughly every few minutes, which provides more privacy. Basic Security Analysis. Randomization as implemented in Windows 1. So enable it Unfortunately, its not perfect, because there are still some ways to defeat or bypass it. The first weakness is that the sequence number contained in Wi. Fi frames is not reset when changing the random MAC address. This sequence number, which is present in most Wi Fi frames, is used to detected retransmissions, and is incremented by one after successfully transmitting a frame. As shown in the picture below, when the MAC address changes because the user connects to a network, the sequence counter is not reset. The last frame from ea 6. Based on this an adversary can reasonably conclude that both frames are sent by the same device. In other words, he learns that the same device was using both addresses, defeating the purpose of address randomization. The second problem is that Windows 1. MAC address when interacting with Hotspot 2. But whats Hotspot 2. Simply put, Hotspot 2. Wi. Fi networks. No manual interaction is needed. Your device automatically determines whether you have the appropriate credentials passwords to connect to a network. Think of this like the cellular network when you get off the plane, your phone automatically finds and connects to a foreign cellular network. Hotspot 2. 0 provides a similar experience for Wi. Fi. In order to accomplish automatic roaming, Hotspot 2. ANQP queries to the Access Point before connecting to it. Wireshark is a free and open source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Description. Aircrackng is a complete suite of tools to assess WiFi network security. It focuses on different areas of WiFi security Monitoring Packet capture and. Last year, I wrote an article covering popular wireless hacking tools to crack or recover password of wireless network. We added 13 tools in that article which were.

Aircrack Windows Packet SnifferAircrack To test the security of your network, we will need aircrack designed by Christophe Devine. This program works under windows and linux, but some of the. Website dedicated to Wireless LAN Security and Wardriving. Includes lots of whitepapers, presentations, tools, firmware, drivers, equipment, and resources. These ANQP queries request detailed information about the wireless network. This information includes the credentials that are needed to connect with the hotspot, whether the hotspot provides internet access or only local network access, etc. Unfortunately, Windows 1. ANQP queries using the real original MAC address. In the first probe request it uses the random MAC address 2a b. These probe requests are used to detect the presence of networks. If theres a Hotspot 2. Windows will send ANQP requests using the real MAC address, in this case 7c 5c f. Therefore an attacker can obtain your real MAC address by advertising a Hotspot 2. Thankfully, Windows 1. ANQP queries if at least one Hotspot 2. Since this standard is not yet widely deployed, few users will have such a network configured 4. Detailed Security Analysis. Want to know all flaws that are present in existing implementations of MAC address randomization And this specifically for Android, Apple, Linux, and Windows Then read my paper Why MAC Address Randomization is not Enough An Analysis of Wi Fi Network Discovery Mechanisms 5 It has everything explained in technical detail. References and Footnotes1 If you have an Intel 7. AC, you can also force Windows 1. Intel 7. 26. 5 AC. Your device will still work, and will support MAC address randomization. 2 Even though authentication based on the MAC address is utterly. MAC address, its still used. C. Huitema. Personal communication, Nov. One notable exception is the Passpoint configuration provided by Boingo. Essentially Passpoint is a synonym of Hotspot 2. If you have this configuration installed, you have a Hotspot 2. Boingo configuration will use Hotspot 2. This means Windows will send ANQP queries to nearby Hotspot 2. M. Vanhoef, C. Matte, M.
