Cracking WPA with Backtrack 4

Credits to g0tmi1k. This video goes beyond just cracking wpa, it also shows how the different tools perform. This video explains the methodology really simple. Let me say that cracking WPA is not like cracking WEP, in WEP you’re exploiting a vulnerability in the way the encryption algorithm is implemented, but in WPA the only vulnerability will be in the strength of the user passphrase. Yes you’ve guessed it, when cracking WPA basically what you’re doing is brute-forcing the user password, in other words the success of your attack will depend on your dictionary or password list. If the user’s passphrase is not in your dictionary, you will never crack the WPA key. There are several types of WPA dictionary list out there, but I highly recommend using rainbow-tables which can be several Gigs in size. How to find them?… Google is your friend!

How to enable password protection in Burg

Burg is a brand-new boot loader based on GRUB. It uses a new object format which allows it to be built in a wider range of OS. It also has a highly configurable menu system which works in both text and graphic mode. We did show you in a previous post how to install and configure burg in Ubuntu. Today we will see how to enable password protection in burg.

configure user and passwords
To add/edit user, use burg-adduser , for example :

sudo burg-adduser --super admin
sudo burg-adduser user1

The –super option is used to specify super user.

To remove user, use burg-deluser :

sudo burg-deluser user1

The password is stored in /etc/default/burg-passwd.
Setup GRUB_USERS variable in /etc/default/burg
Here is an example:


This means user1 can boot Ubuntu, no password is needed for Windows, user1 and user2 can boot other OS besides Ubuntu and Windows. Superusers can boot any OS and use system-wide hotkeys like `c’ to enter console mode.
Generate burg.cfg with update-burg

sudo update-burg

You can use burg-emu to check the configuration before reboot:

sudo burg-emu
