[Tutorial] Wireless Havoc With MDK3!! (I)

Introduction:


This is the first part of the MDK3 series, you will find out the basic dangers you will face while using wifi. Articles about bigger dangers will come later. Please read all the episodes and enjoy!!


MDK is a proof-of-concept tool to exploit common IEEE 802.11 protocol weaknesses, and it does that perfectly. Some of its exploits are beacon flood mode, deauthenticating connected clients, cracking hidden essids, crashing wireless APs etc. We we talk about some of them in this article.

And guess what, this little program file is no more than 208 Kb when downloaded, it wont consume more than 2-3 Mb in your disk.. but you will find out how powerful it is after you read all the episodes.


Installation:

MDK3 is a tool already included in BackTrack 5 R1.
If you want to install it in other distro then:

sudo apt-get install mdk3 --> for debian based 

sudo yum install mdk3 --> for redhat based

If it is not already there in repo then get a copy from here and manually install it.


Installation process:

tar -xjf mdk3-v6.tar.bz2
cd mdk3-v6
make
make install.

* you may get whole pages of errors when you enter "make", but ignore it and proceed to make install, it will install mdk3 fine. If it doesnt then please leave a comment, I will take a look at it again. :)

Update: If it doesnt work, you may need to edit your Makefile. ( I had to do so in Ubuntu 12.04) 

Open Makefile
change this line: LINKFLAGS = -lpthread to
                                 LINKFLAGS = -pthread
make && make install

Help page:

Before starting lets have a look at the help page of mdk3:

As mentioned in the third line, mdk3 --fullhelp will give us with a detailed help page. Please have a look at it in your own terminal.

The test modes we are going to be using in this sessions will be, "b , a and d" These are the most interesting modes ever that you can use to play prank to your neighbour or even worse can make him suffer.


Please stay tuned, I will post a detailed tutorial in my next post, as will be too long if i include all of them in this single post. :)
