Wireless networks are common in enterprise environments, making them a prime target for penetration testers. Additionally, misconfigured wireless networks can be easily cracked, providing penetration testers with a great deal of valuable information about the network and its users. This article explores some of the most widely-used tools for different aspects of wireless network hacking.
Kismet is one of the most famous Wi-Fi hacking tools available. It is a network sniffer capable of monitoring 802.11 wireless traffic as well as other wireless protocols, such as Bluetooth and Zigbee.
After gaining access to a wireless network, a penetration tester needs to perform network sniffing and traffic analysis to take advantage of that visibility. A couple of different options exist for monitoring and dissecting the traffic flowing over wireless networks.
Wireshark is designed to be an intuitive and easy-to-use tool, but it is designed for network traffic analysis. This means that, while the tool may be easy to use and invaluable for wireless hacking, an understanding of network fundamentals is necessary to use it effectively.
Packet injection enables a penetration tester to inject data into an established network connection. This helps perfrom denial of service (DoS) and man-in-the-middle (MitM) attacks against wireless network users.
In some scenarios, performing wireless network hacking on a laptop would be conspicuous, while a mobile device would be essentially invisible. A few different platforms exist for performing penetration testing against wireless networks from a mobile device.
Kali Linux NetHunter is an open-source version of the Kali Linux operating system for Android devices. It provides several different tools for Wi-Fi hacking and mobile penetration testing, including Wireless 802.11 frame injection and one-click MANA Evil Access Point setup.
Wireless network hacking is an essential skill set for the modern penetration tester. While the tools described in this post are organized into categories, many have functionality that spans multiple different areas. Gaining familiarity with a few different wireless hacking tools can be a valuable investment in an ethical hacking career.
The airport command is more powerful than just being able to list information on the current wireless network though, you can actually manually adjust any wi-fi settings, network card settings, troubleshoot networks, change security types used on a connection, capture packets into a pcap file, join and leae networks, disassociate from a wifi network, prioritize routers and networks, see signal strength and interference, adjust wi-fi hardware drivers, and perform a huge variety of network troubleshooting functions too. This is easily one of the most powerful ways to interact with a wireless card on a Mac.
A wireless penetration test will examine your network using a methodology similar to the standard wired penetration test. However, they will focus on the wireless as the gateway to exploit your vulnerabilities. Thus selecting the right partner to conduct the wireless penetration testing is an important decision. Look for certifications such as OCSP, OSCE, GPEN, CEH, CPT, and CWNP.
Select a company that has technical expertise. If their knowledge is both deep and wide, they will be able to dig deeper and therefore provide you with information that is more valuable. Ask for an example of a deliverable report from a similar wireless penetration test. The report should be detailed and self-explanatory. With the proper business acumen, the testers can tailor their work to you vertical and its regulatory mandates. Penetration testing should mimic a real-life attack in as many ways as possible.
A proper understanding of these diverse bodies is what will make your wireless penetration test relevant, tailored to your technology, and serve as a third-party audit for your company. The experienced tester will know to look at all wireless technologies. This will included looking at point-to-point links that are often licensed links from the FAA. Looking at Bluetooth (802.15) will be helpful exposing any vulnerabilities that exist in the use of that technology within your network.
Another aspect of testing is rogue AP analysis. Testers can locate rogue devices through RSSI signal analysis and triangulation. The penetration tester should be aware of Ad Hoc networks. Bogus Free-Wi-Fi open networks and malicious rogue clients. Also make sure the testers look for devices that are in the environment but connecting to SSIDs that not authorized by your company. By connecting a corporate asset to another Wi-Fi network, it can be unsafe for a plethora of reasons. Some of these are watering hole attack, phishing attack, MITM attack, etc.
Any wireless transport mechanism will have a MAC layer with the exception of DECT as it operates in a closed phone system and not over TCP/IP endpoints. Bluetooth, which is a wireless personal area network (WPAN) defined by IEEE 802.15.1. Understand Bluetooth operations and hacking becomes relatively easy. Zigbee is another WPAN. ZigBee is defined by 802.15.4, which was created for low data rate transmission that allows a device a very long battery life. ZigBee also uses the MAC layer so knowledge of its working is also necessary if this technology is in use. As previously explained DECT does not use a MAC and unless there is an IP that makes it an Internet of things (IoT) device the only concern would be decoding and eavesdropping. A DECT device would not be a gateway into your IP network.
Aircrack-ng has many packets and binaries, and all of them are used for achieving exciting results. Of course, we will need the metapackages, which will also be covered in the tutorial. So, brace your keyboard, fellow hackers, and get with wireless (WPA/WPA-2) networking cracking in Kali Linux.
Airodump-ng is used to sniff the data packets around the network in promiscuous mode. It lists the WiFi networks around us and gives us detailed information about them i.e MAC address, number of clients connected to a given network, BSSID, channel name, etc. This helps in targeting the desired network. We will use the following command to sniff packets on a particular wifi interface (wlanmon in our case):
Setting up your router with different SSID per band helps keep your network organized and more predictable.I had just bought an iphone with 5G wifi AC but the router that supports 5G AC kept connecting the iphone to the 2.4G band. After assigning a separate SSID for each band and telling my iphone to only use the 5G SSID the issue was fixed.In your case the 6G band may be a poor connection so the router and client are auto selecting the 5G band.
Most travel routers offer speeds in the region of 300Mbps, which is more than fast enough for streaming even very high definition content, and faster than most networks. So I think that no travel router will really improve that speed so any of them will pretty much give you the same speed. The only option would be to invest in a mobile hotspot, which bypasses the wifi entirely and connects over a 4G network which could deliver faster speeds. If these are available in the country you are traveling in, they can be faster than WiFi in some cases.
Yes, so travel router devices can either extend an ethernet network into a WiFi network, or extend a weak WiFi signal into something your devices can connect to. Of course this only works if there is a wifi connection to extend. 2b1af7f3a8
