This does take up computing resources, and can add another layer of troubleshooting if a problem arises, such as Backtrack not recognizing a USB adapter. The bottom terminal in this example will pop up and say WPA Handshake in the upper right when this happens. Run the command “airmon-ng” to see if your USB adapter shows up, if it doesn’t then some troubleshooting as to why it is not will have to be done. If you are stuck using this method, thinking about how the password might be structured will be crucial along with computing power.

The problem with WPS is, it has a flaw in it that lets someone go around the encryption. There is three ways to install Backtrack, install to the hard drive, boot off a DVD or flash drive, or run it in virtualization.

Crack WiFi Password with Backtrack 5 (WiFi password hacker)

The information in this book is to give the reader a basic overview of the current hacks against wireless routers with Backtrack 5, and hopefully it has done that. For this example I edited the text dictionary file and put the password in to show what it looks like when it is found. Open two terminal windows. If you have an older laptop or older computer then the ISO may be better.

Once you know the adapter is connected and operating run this command to get the adapter into monitor mode. Look for the WEP protected network in this tutorial we are taking “pack” as my target. Wwifu it boots from the DVD it should come to the following menu. The first thing we need to difu is enable the wireless USB adapter. This is the same as the above booting off the DVD.


There are other ways such as Rainbow Tables, or the video card attack, but the simplest or easiest way to wiuf WPA is to use Backtracl Force. It will run until it finds the wireless password usually hours. If you have never used Backtrack before all you really need to know it is the best software to use for Digital Forensics, Intrusion Detection and Penetration Testing. Introduction Backtrack 5 R3 is a notorious Digital Forensic and Intrusion Detection software bundle with a whole lot of tools for Penetration Testing, It is based on Linux and includes plus tools.

If the password is easy then it will find it quick, if it is a long paraphrase with many different number letter combinations then it will be much harder. But when WPA became the standard it became much harder to do, using the dictionary attack method was the only real option. In order to carck the WEP you will bafktrack to capture all the data of the target into file. If a router has WPS enabled then cracking the encryption is no longer necessary. Once aifu cracking is successful you will be given Key,just remove the inbetween colons from the key and use it.

A dictionary attack is one of the easiest to understand but the least likely to find a password. Installing to the Hard drive Any existing Operating System will be wiped out and only Backtrack will be installed if this is done. To do this we do the following command.

Now when the new interface mon0 will be created you can see the new interface by typing ” iwconfig mon0 “. At this point we could simply wait for someone to connect wirelessly to the router.

Here we are going to setup the adapter to do a data capture on the AP point we selected. If a router has WPS enabled it can usually be cracked in two to ten hours.

wfiu Now you will need backteack find the WEP network around you,you can do it by typing the following command:. The data capture could be copied between multiple computers to split the things up. Then click the link to the torrent and the client will download the file. VMware Player can be downloaded here http: If nothing comes up then no WPS enabled router is within reach. Login to your Backtrack linux and plug in the Wifi adapter,then open the new consol and start typing the following commands:.


The way this works basically is that there is a large badktrack that you use to throw as many combinations of words as possible at the WPA encryption until it cracks. This is not because the adapter is not supported it may or may not be. WPS makes it easy for wireless devices to find and connect to a router. This is often the last resort because while it does work it depends on the dictionary used and the computing power.

To see all the connected cards to your system simply type” iwconfig ” or you can find it by typing backtgack airmon-ng “.

The user name is root and the password is toor. In the second terminal window run the following command. A to F on one G to Z on another. Reaver is one of the best tools to come along in a long time.

Buying multiple routers to play with is also a good idea. If someone knows the person then they may be able to guess the password but otherwise this can take a long time and never find anything.

Reaver has many option or switches it can use to deal with these problems. At the command prompt type startx to enter the GUI.
