Welcome to Section six in this section, we're going to cover wi fi hacking.
I'm going to walk you through a big picture overview of what exactly wi fi is and how this is one of
the most common ways that black hunters get access to networks, access to information, and how you
can also learn how to hack wi fi yourself.
Right.
So let's go right ahead and jump in here.
So we're going to go over specifically what is Wi-Fi?
I want you to get a real understanding foundationally of what exactly Wi-Fi is.
Right.
We have that acronym there, but we don't really know oftentimes how it works, why it works and the
back story of it.
Right.
We're going to go into that.
We're going to go over how hackers break into Wi-Fi, what are the most common methods.
And then we're going to go over setting up or Calli machine for Wi-Fi hacking.
We're going to walk through the hacking.
We're also going to walk through the WPA and WP to hacking as well.
So what exactly is Wi-Fi?
So Wi-Fi is a wireless networking technology that allows devices such as computers, laptops, desktops,
any other mobile devices to interface with the Internet.
So if you look at the right hand side over here, you notice that you have all these devices, right?
You have the computers, you have your cell phone, you have a laptop.
They're all connected to a wireless access point.
Right.
Which is typically like a modem that serves as also Wi-Fi connection, which is a wireless access point
that allows devices such as your cell phone.
If you're walking around at home.
Right.
You don't need to connect your cell phone through a wired cable.
Right to your modem.
All you got to do is sign up to the Wi-Fi and you'll have the instant access to that network.
That wireless access point serves as the actual Wi-Fi connection for any other devices in the network.
So just think about a wireless access point as the same thing as an amplifier and what an amplifier
does for a home stereo.
It amplifies the connection and amplifies the sound.
And so an access point takes the bandwidth coming from a router and stretches it out so that more devices
can get on the network.
And sometimes you'll just have like a wireless access point that is connected to a router.
Right.
You have an actual router that you can have for an actual access device.
And sometimes you have a standalone wireless access point.
Right.
That will allow the network to stretch its actual coverage.
And so this is essentially what Wi-Fi is, right?
It's a wireless network, technology allowing devices to be connected to the Internet through the network
on a wireless basis.
And so now let's go over how hackers break into Wi-Fi.
So here are some of the common methods that they use to break into the actual Wi-Fi networks.
So we have sniffing here.
And what snipping is it allows hackers to hijack any packet of data that is being transmitted between
a device and a router.
So in between that connection, right.
There's packets of information that are going back and forth and the hacker is able to hijack any of
those bits and pieces of information while they're being transmitted.
And then we have spoofing.
And how this works here is, you know, typically when you log into a specific network, wireless network,
you have your saved login information as far as your username and your password.
And so what a black header does here is they set up a network that is stronger and that allows your
particular device to connect to whatever saved information there.
As far as the login, the password.
Right.
The credentials then get saved.
And so then that information is now available to that, you know, Blackadder and then they're able
to actually get the login information to the actual network that you're looking to actually connect
to.
And then there's word driving.
This is where hackers are physically driving around in their car and they're spotting and looking to
exploit wireless local area networks while they're driving around.
And this is typically for like, you know, businesses that have networks that, you know, expand to
a given location given area.
These are folks that are actually driving around looking to exploit these types of networks.
And then we have encryption hacking.
This is where hackers use brute force on the router in a bid to crack its decryption key.
And then finally, here we have brute force.
I really want to give you a full explanation here.
What brute force is this is the equivalent of trying every single key on the key ring and eventually
finding the right one.
So let's say you have a set of numbers that you're working with.
One through 10 brute force is essentially where you're going through each and every single combination
within that one through 10.
Right.
You're trying one trying to three for know all the numbers and you're essentially putting in all your
force, all your capabilities to be able to take over that particular network.
Or to get into that particular information, whatever that may be, it's doing it by all means necessary,
essentially, or trying everything in the book, throwing everything at everything in the kitchen sink
to essentially be able to break into that network or whatever data or application that you're breaking
into.
And so this is a quick section overview here of wi fi hacking.
We're going to go a lot more in-depth in these coming lectures.
Anthony is going to walk you through a lot more examples, but this is more just a quick overview of
understanding at a foundational level, wi fi is and what are some of the common methods that hackers
use to break into wi fi?
So that's going to be here for this one.
And we'll see you on the next one.
