  3. # WiFi WEP Crack BackTrack bash script
  4. # by The Pirat. thepirat000@hotmail.com
  5. #
  6. # Use this script to easily execute the commands to crack a WEP WiFi password.
  7. # (airodump, aireplay, wpa_supplicant, aircrack, ...)
  8. #
  9. # HOW TO USE:
  10. # Start backtrack GUI and open a console
  11. # Make sure you have "Konsole" installed (apt-get install konsole)
  12. # Copy-paste this script to a new file i.e. WepCrack.sh
  13. # Give execution permission to this file:   chmod +x WepCrack.sh
  14. # Execute the script in this file:          ./WepCrack.sh
  15. #
  16. # Enter the Interface name (default is wlan0)
  17. # Enter the monitor name (default is mon0)
  18. # Wait for the monitor until you see the WiFi you want to crack in the list (is must be WEP)
  19. # Press CTRL+C
  20. #
  21. # Enter the channel where the network is working (or copy-paste it from the list)
  22. # Enter the MAC Address of the AP (or copy-paste the MAC from the list)
  23. # Enter the essid of the AP (the WiFi network name) (or copy-paste the name from the list)
  24. # Enter the name of the generated capture file (or press enter to use the essid as the file name)
  25. #
  26. # Now, the script will open 3 windows to:
  27. # - Capture the network packages (airodump)
  28. # - Fake an authentication (wpa_supplicant)
  29. # - Inject packages
  30. # And also you will see the main window with options to execute more commands.
  31. #
  32. # When you have captured enough packages, select the command 4 (Aircrack) to launch the WiFi password crack process.
  33. #
  34. # NOTES:
  35. # You can abort the process at any moment by pressing CTRL+C and relaunch the script later, without losing the previous captured packages.
  36. # Tested in backtrack versions 4 and 5
