Choosing a Wireless Adapter for Hacking Null Byte Wonder. How. To. Welcome back, my budding hackers. So many of you are interested in hacking Wi Fi that I have decided to revisit my Wi Fi Hacking series with some updated and more in depth material. I strongly suggest that you look at some of my earlier posts, such as Getting Started with Terms and Technologies and Getting Started with the Aircrack ng Suite of Wi Fi Hacking Tools, before continuing here. If youre ready, you can also check out our updated 2. Wireless Hacking Requirements. When it comes to Wi Fi, the question I probably get asked most often is, Which wireless adapter is best for hacking Well, lets find out. Good Wi Fi Hacking Software. Before we address the hardware necessary to hack wireless networks, let me once again recommend the Aircrack ng suite of hacking tools. Nothing else in our open source world quite compares to the power and versatility of Aircrack ng. Fast Powerful CPUA fast multi core or multi processor CPU is certainly helpful. When cracking WEP passwords, which is a statistical crack, you need to crunch a lot of numbers, and the faster the CPU the better. The WPA2 crack basically involves crunching millions of password hashes, which is also very CPU intensive.

One caveat, though. The difference in speed is not huge. You can only expect a 2. CPUs and the fastest. More cores, on the other hand, will improve performance significantly. The Right Wireless Adapter. Techniques Of The Selling Writer Pdf more. Beyond the two primary tools listed above, the next most important requirement is good wireless adapter. To really be effective at wireless hacking, your wireless adapter should have two primary features.

A dictionary attack may take days, and still might not succeed. Also, good dictionaries are huge. The ability to enter monitor promiscuous mode. The ability to inject packets and capture packets simultaneously. A wireless adapter that cant do these two critical features doesnt mean that you wont be able to crack wireless, but it will mean that it will be so slow that it renders it effectively impossible. Wireless hacking in a world of WPA2 encryption can be a relatively slow process with the best equipment.

Image by SADMINNull Byte. Monitor Mode. Network adapters, whether wired or wireless, are designed to only capture and process packets that are sent to them. With Kali Linux, hacking becomes much easier since you have all the tools youll ever need. This tutorial will get you started on your journey of hacking with Kali Linux.

In the wireless world, the equivalent is monitor mode. This enables us to see and manipulate all wireless traffic passing through the air around us. Without this ability, you are limited to using your wireless adapter to only connect to wireless APs that accept you and authenticate you. That is not what we are willing to settle for. In the Aircrack ng suite, we need to be able to use Airodump ng to collect packets. Packet Injection. Most wireless attacks require that you be able to inject packets into the AP while, at the same time, capturing packets going over the air. VERY few wireless cards are capable of doing this. As you can imagine, wireless adapter manufacturers are NOT looking to add features to their standard wireless adapters to suit OUR needs. Most wireless adapters built into your laptop are designed so that mom and dad can connect to AOL and send their email. We need something much more powerful and versatile than that. If we cant inject packets into the AP in Aircrack ng, this is the function of Aireplay ng, then it really limits what we do. For instance, in our WEP attack, we will be forced to passively wait for packets to traverse to air in order to capture the ever valuable and vulnerable IVs. Since we need to capture around 5. WEP, we could be waiting for days and weeks on a little used AP. With packet injection capabilities, we can reduce that to a few minutes by injecting the AP with ARPs. Linux vs. Aircrack Ng Compatibilty. The first issue we need to address in choosing a wireless adapter is making certain that it has drivers for Linux. In 2. 01. 7, most wireless adapters now have Linux drivers, but that wasnt always the case. Its important to note, though, that Linux compatibility is far from being an optimal wireless hacking adapter. It is only a minimal requirement. Probably the most important feature we need is compatibility with our software of choice, Aircrack ng. The developers of Aircrack ng maintain a compatibility list on their website that includes all of the adapters they have tested and their level of compatibility. This is just a snippet from Aircrack ngs compatibility list. Note that you will need the chipset for your wireless card to find its compatibility on this chart. The first column indicates whether the chipset is supported in Windows for Airodump ng packet capture in monitor mode. The next column indicates whether that same capability is available in Linux for that chipset card. Finally, the last column indicates whether that chipset is supported for Aireplay ng packet injection in Linux. Internal vs. USBIf you choose to install Kali or Back. Track in a virtual machine VMware or Virtual. Box, you will need an external wireless adapter. This is because the virtual software hypervisor pipes your wireless access to a wired connection in your virtual machine. As a result, Kali does not have a wireless device to work with. Since most built in wireless adapters in your laptop are probably inadequate to crack wireless, you are better off purchasing a USB wireless adapter for wireless hacking. For long range, our community recommends the Alfa AWUS0. NHA Wireless BGN USB Adaptor. For a more discreet form factor, the Panda Wireless N USB Adapter is the most popular adapter among our newer hackers. The small but mighty Panda PAU0. Null Byte. Image by SADMINNull Byte. If you choose to install Kali as a dual boot system, you can use your built in wireless adapter for wireless hacking, if its on the Aircrack ng compatibility list. Although you can hack with wireless cards not on that list, you had better be very patient as this process make take you days or weeks without the proper adapter. To effectively hack Wi Fi passwords, you will need a proper wireless adapter. Make certain that you check the Aircrack ng compatibility list to make certain that your wireless adapter has the necessary features to make your Wi Fi hacking fast and effective. If youre looking for a low cost way to jump into Wi Fi hacking, consider grabbing a 3. Raspberry Pi with your adapter to build a Kali based hacking computer on a budget. You can check out our guide here on setting it up. The Kali Pi can get you started hacking most networks. Image by SADMINNull Byte.
