BackTrack 4 Beta released


The Remote Exploit Development Team has just announced BackTrack 4 Beta. BackTrack is a Linux based LiveCD intended for security testing and we’ve been watching the project since the very early days. They say this new beta is both stable and usable. They’ve moved towards behaving like an actual distribution: it’s based on Debian core, they use Ubuntu software, and they’re running their own BackTrack repositories for future updates. There are a lot of new features, but the one we’re most interested in is the built in Pico card support. You can use the FPGAs to generate rainbow tables and do lookups for things like WPA, GSM, and Bluetooth cracking. BackTrack ISO and VMWare images are available here.

    Just wondering, but at the startup, instead of typing: startx Has anyone had success with using the: bt4-crystal option? I get a screen, but the “startbar” and top bar are just boxes, with nothing in them. Am I the only one having this problem?

    -just wondering. Haven’t tried a re installation.
    -using the .iso file. through qemu on a windows xp comp.

    d00d, have you tried clicking on the desktop? right click gets you a console, and left click gets you the menu for EVERYTHING. No one has any interest in figuring anything out….

    Hi, Hameed,

    There is no need to install root, only run sudo command and change your password user name as a root and password. Reboot system and login as root.


  5. Zaac says: been trying to run BT3 in live mode of the CD
    but I keep getting a split screen (three horizontal columns)Has anybody else had this problem? If so what’s the remedy?

  6. posted says:

    well, just download this wep-atack-1.9 program run under windows,

    go to tools -> parse wifi
    wait for 2 minutes,
    it will show the list of wep enabled wireless networks list,

    select which one you want to hack and click on GET KEY button,

    you should wait for 10 minutes, then it will popup a key.

    note : it is working for WEP encryption only, not for WAP

  7. MP says:

    It intstalls on the Dell 15 Studio series but the card is limited in its functions(no injection). You need a special Broadcom driver. Even got wpa_supplicant working on this Dell.

    Had to order a usb adapter card that can handle injection and work with all the tools BT4 has. I heard the ALFA AWUS036H works great. I’ll be testing it soon.

  8. klang808 says:

    does the bt4 work with desktop? what tools do I need?

  9. klang808 says:

    any BT4 expert hire? pls. add me on yahoo messenger, its klang808 thx

  10. {LCD}STELIOS says:

    I am using BT4 on live CD, with Alfa AWUS036H RTL8187, I have started networking in terminal but my adapter is not working. Is there some thing I am missing (probally) or some thing else I have to do?
    I can’t seem to find any more info on the subject.
    Thanks in advance.

  17. Jambrose says:

    Hey, does anyone know if there is any way to install wifi device drivers on bt4? My wireless adapter is Atheros AR5B91. I’ve been Google-ing for a couple days now, and this seems to be a common problem for a lot of people. Still no solution yet though.

    Any help is greatly appreciated

  18. Licous says:

    Hey, i really need help to get this working..
    wel, BT seems to work great tho, but i cant get the wireless thingy (intel (r) wifi link 5100 agn) to work..

    Could any of you make a little guide for me( and the others with the same problem) ? i am very new to BT, so a noob friendly guide would be very helpful. Thanks!

  19. Licous says:

    i am using BT4 btw

  20. Erik Honnecker says:

    I´m using BT4 Beta VMware ISO in Vista Ultimate with ALFA awus036H. Lots of trouble to make it work. For example, to have VMware detect USB I had to upgrade from VMware Player to Workstation and then start VMware Arbitration Service, but after that it´s plug and play. So now it rocks!

  23. Resistol says:

    I’m also having trouble with my ar5b91 wireless card. BT3 and 4 do not detect any wireless devices :-( Any ideas? Thanks in advance!

  24. Th3_uN1Qu3 says:

    For Ahmed: Cracking WPA requires a dictionary (and if the password is not a dictionary word you’re screwed), or some huge ass tables (they were like 40GB last time i looked). And it does take time (read: days and even weeks on an average laptop).

    Fortunately there’s still plenty of WEP (in)secured networks where i live.

  25. FJ says:

    Hello Friends!
    I have read all the post on this page and must admit that I am impressed with your knowledge. I am new to the world of BT4. I have got a MacBook pro with intel core duo and would love to have BT4 up and running. Plesae point me in the right direction as to what else i will need to make it work VM wise and network card wise. Thanks

  32. vr44 says:

    anyone know about the 5100 for injection?

  33. John says:

    Steve, type startx then hit enter.

  34. brett says:

    I can confirm that the Broadcom 4312 REV 1 fully supports monitor mode & injection. After searching exhaustively for a solution, I had to upgrade my kernel to and use the FWCutter on the b43 driver, but it does work.

  35. Charlie says:

    I have a problem installing backtrack4, I’m not very used to this type of software. I can’t get past the user name login , the keyboard won’t type for the password. I redid it several times it’s always the same. I looked at my bios and it doesn’t seem like an obvious reason. Could you give me an answer to this it’s probably and easy one.
