- [Presenter] Let's go over aircrack-ng.
Aircrack-ng is actually one of the most popular tools
or suite of tools that can be used for wireless pen testing.
So within the aircrack-nging suite,
'cause it's actually a suite of tools,
you have different tools
that can allow you to monitor wireless traffic.
Either, also perform packet capture, right.
So, you can also export that packet captures,
and any other data to text files,
so that you can do you know,
further analysis by other third party tools.
Like Work Shark, and you know, some other ones, right.
So, now it also provides a series of tools
for attacking the wireless network.
Wireless access points and of course wireless routers,
and also the wireless clients, right.
So, you can perform replay attacks,
the authentication attacks, create fake access points,
and also perform other attacks using packet injection.
Now talking about packet injection, you need to make sure
that you have a wireless card that is compatible,
and capable of doing packet injection.
And as you know, in lesson three,
I cover the different wireless adapters
that I personally use.
And I also have some recommendations in there.
And then, so I definitely advise you to revise that lesson,
and also make sure
that you have a compatible wireless adapter,
before you start actually playing with these tools, right.
So, now aircrack-ng comes by default in Cal Linux,
but you can actually download it for-
from the website that I'm highlighting here.
So, aircrack-ng.org.
Now, you can also check their Wiki
for a few troubleshooting tips, right.
So, in case that you're running to province
with the wireless adapter, like I mentioned before
or whatever operating system
that you will be running aircrack-ng from.
Now, I typically use it in Cali.
Since it works, you know, most of the time.
Assuming that you have a comparable wireless adapter.
And that they, you know,
they also made a few adjustments for you,
that, you know, will allow you to, you know,
reduce the amount of headaches
that you probably will encounter
with different comparability issues,
and probably,
you know, different kernel issues,
depending on your environment.
Right?
So again, you know, I actually just use it,
you know typically outta the box,
fairly simple in Cali, right.
Now this is a link for their Wiki,
as I was mentioning before.
And I'll advise you to, of course, you know, revise it.
And they have really good troubleshooting tips,
in there for you, right.
Now in the next few lessons,
we will cover each of the most popular tools
that are part of these, you know, suite of tools,
part of aircrack-ng.
Now in lesson five, we will go over on how to crack WEP.
And also in lesson six, we will go over how to crack a WPA,
with pressure keys.
But let's quickly glance at the tools
that part of this suite, right.
So, first you have airbase, right.
So, airbase dash NG, so everything, you know,
ends with an NG here. Right.
So, airbase is a multi-purpose tool
that is actually created for attacking clients,
instead of the actual access point or the wireless router.
Right? So, now aircrack.
It's WEP, and also WPA key cracking program, right.
So, and that's what we're gonna be using whenever we go,
and crack both, you know,
WEP and WPA later in the course.
There's also air-DCAP, right.
And that's a-
the encryption tool that capture, decrypt WPA,
WEP, and WPA to a capture files, right.
Now there's also air-decloak.
And basically, this tool is used to remove web cloaking,
right?
And from a capture file.
Basically, what this web cloaking is,
is a technique that is actually used for-
by, you know, some wireless network infrastructure devices
that inserts frames into the air,
with a goal of actually fooling the attacker to think
that they are real, right?
So to think that this actually inject frames are real,
and to try to mess up the statistical analysis, you know,
of that attacking tool, right?
So, basically this is used to prevent an attacker
from cracking the key, right.
So, now this tool, what it does,
is actually tries to remove WEP cloaking for this purpose.
You also have air-replay,
which we are gonna be using later.
It's used to inject and replay wireless frames.
Air-graph is actually to graph wireless networks.
Air-mon is the one that enables you to enable,
or disable monitor mode on wireless interfaces.
Right, so you're gonna see this in action,
later in the course as well, right.
So, you have also air-o-dump,
which is actually to be able to capture,
the row eight to eleven frames over the air, right.
Air-o-lib,
it's actually a tool that that is used to precompute WPA,
and WPA, to pass phrases in the database,
to use later with then aircraft-ng, right.
You also have air-serve,
which is actually a wireless card, TCPIP server,
that allows multiple applications
to actually use a wireless card, right.
Now, air-tun is used to create virtual interfaces.
There are virtual tunnel interfaces.
And then, you also have packet-forge-ng, which creates,
you know, different types of encrypted packets.
That then can be used for injection at-
you know, as well.
Now again, you know, in the next few lessons,
we will go over the most popular tools
that are part of this suite.
And then later on,
you're gonna actually see them in action.
Whenever we crack WEP and also WPA.
