Welcome back, my greenhorn hackers. When Wi-Fi was first developed in the late 1990s, Wired Equivalent Privacy was created to give wireless communications. May 17, 2017 - In this Aircrack-ng tutorial, you will learn how to use Aircrack-ng to crack WPA/WPA2 wifi networks. With Aircrack-ng you perform Monitoring,.

Kali Linux can be used for many things, but it probably is best known for its ability to penetration test, or “hack,” WPA and WPA2 networks. There are hundreds of Windows applications that claim they can hack WPA; don’t get them! They’re just scams, used by professional hackers, to lure newbie or wannabe hackers into getting hacked themselves. There is only one way that hackers get into your network, and that is with a Linux-based OS, a wireless card capable of monitor mode, and aircrack-ng or similar. Also note that, even with these tools, Wi-Fi cracking is not for beginners. Playing with it requires basic knowledge of how WPA authentication works, and moderate familiarity with Kali Linux and its tools, so any hacker who gains access to your network probably is no beginner.

NOTE*USE THIS WITH PERMISSION OF OTHERS WIFI IN WHICH YOU ARE TESTING THIS TESt USE IT AT YOUR OWN RISK!! If you don’t have a torrent program, then click on “ISO” next to the appropriate version of Kali and select “Save” when the download notification appears in your browser and save it to a easy to remember location. If you do have a torrent program, then I highly recommend using the torrent option, as it is much faster. Click on “Torrent” next to the appropriate version of Kali and Save the “.torrent” file to an easy to remember/access location. Now open your Torrent program (I use uTorrent), click “Add new torrent,” select the “.torrent” file, and select the appropriate options to download it.

Now wait for Kali to download, this might take several hours, depending on your internet speed. You will now be presented with a Hardware window. Firefox.

Select Memory in the left pane of the window, and slide the slider on the right side to at least 512 MB*. Since I have 8 GB of RAM on my computer, I’m going to put it at 2 GB’s (2000 Mb’s). *Note, you should give a virtual machine a maximum of half the RAM installed on your computer. If your computer has 4 GB of RAM, then the max you want to slide it to is 2 GB.

If your computer has 8 GB, then you can go to a max of 4 GB, etc Now highlight Processors in the left pane. This option really depends on your computer, if you have multiple processors, then you can select two or more. If you have a regular computer, with two or less, then I suggest leaving this number at one. Moving on, click on Network Adapter in the left pane. On the right side, move the dot to the Bridged (top) option. Now click on the Configure Adapters button. In the small window that pops up, uncheck all the boxes except for the one next to your regular network adapter and hit OK.

You can now click on Close at the bottom of the Hardware window and then click on Finish in the Wizard. Disconnect from all wireless networks, open a Terminal, and type airmon-ng This will list all of the wireless cards that support monitor (not injection) mode. If no cards are listed, try disconnecting and reconnecting the card and check that it supports monitor mode. You can check if the card supports monitor mode by typing ifconfig in another terminal, if the card is listed in ifconfig, but doesn’t show up in airmon-ng, then the card doesn’t support it. You can see here that my card supports monitor mode and that it’s listed as wlan0. Type airmon-ng start followed by the interface of your wireless card.

Mine is wlan0, so my command would be: airmon-ng start wlan0 The “(monitor mode enabled)” message means that the card has successfully been put into monitor mode. Note the name of the new monitor interface, mon0. EDIT: A bug recently discovered in Kali Linux makes airmon-ng set the channel as a fixed “-1” when you first enable mon0. If you receive this error, or simply do not want to take the chance, follow these steps after enabling mon0: Type: ifconfig [interface of wireless card] down and hit Enter. Replace [interface of wireless card] with the name of the interface that you enabled mon0 on; probably called wlan0.
