So now it's time to crack the whip key for client list networks, because I know what you were thinking.
OK, fine, this works.
But what about client was networks?
Well, air crack energy has two attacks, the chop chop and the fragmentation attack.
And these can be used to crack the whip key of a wireless client with no associated clients.
Now, both of these attacks are used to obtain updegrave file from the wireless network, so Piguet
is the pseudo random generation algorithm that's used to generate the key stream that's used in Web.
It's not the Web key, right, so it cannot be used to decrypt packets.
It can, however, be used to create new packets that can later be used for injection.
There's a method to our madness.
So the first technique we're going to use to obtain the file is the fragmentation attack.
Fragmentation attack requires at least one data packet to be received from the AP in order to initiate
the attack.
But before getting started with this attack, I want to make sure that there are these known assumptions
in your minds.
First off, maybe obvious that you were close enough to the AP to send and receive packet's.
But just because you're close enough to receive package doesn't necessarily mean you'll be able to transmit
packets to the access point.
You can work that out on your own work practice.
Now, there are some data packets coming from the AP, so a quick way to check for data packets is to
run arrow dumping and then see if the data field is increasing.
And of course, the AP needs to be using web open authentication.
Great, so let's start.
And as usual, our wireless card first needs to be placed in a monitor mode on that channel number of
the access point and a fake access point with weap and open authentication needs to be running.
Now we need to start an arrow dump energy session and we're filtering on the access point channel and
be abscessed so that we can save the capture to a final.
Now, notice in the dump output, there are no clients associated with the access point.
So in order to be able to communicate with the access point, we need to conduct a fake authentication
attack against it.
And we will run the fake authentication with a free association timing of 6000, so it does not time
out you with me.
Cool.
So now airplay will keep the session alive.
So we don't need to worry about relaunching the attack every time the fake association times out.
So the fragmentation attack requires at least one data packet to be received from the AP in order to
initiate the attack, and we have one data packet now, so let's open up a new term window.
And we will launch the fragmentation attack against our app using the basic syntax.
I'll give both sides of the access point with the B parameter and the Mac address of the W Landsborough
with each parameter.
OK, so airplane engine is starting to send packet.
So the attack sends out a large number of packets, all of which must be received by the AP in order
for it to be successful.
OK, so therefore you have to have a good quality connection like I was in before and be reasonably
close to the AP.
All right, so once we launch the attack, airplane starts listening for a packet use and then when
a candidates found, we are prompted to use it for the attack.
OK, so now candidate packet is found just in her, why, and wait for it.
OK, so sometimes this happens, unfortunately, the fragmentation attack did not work, and naturally,
there are several reasons why this could be.
Attack may fail against access points that do not properly handle fragmented packets, but do not give
up because there is an alternative way to crack client was swept networks.
That's where the chop chop attack may work, where the fragmentation attack may not.
