Hello, guys, and welcome to another video for this chapter.
Identifying the vulnerable devices and services on Internet Router, it would be
difficult without leaving logs and other traces on the network.
However, there is a way to capture and use
this Wi-fi activity without ever connecting to the wireless network.
So before you do that in your own network, I would suggest that you start with a
sheet of paper and you can write down all your connected devices, that includes
things like smart TVs smart speakers, laptops, tablets and phones,
or any other device that might be connected to your network.
Network administrators and engineers are very familiar with this stuff.
It's the first step in exploring any network that you're not familiar with.
So please go ahead, do an inventory of the devices on your network, identify
them, and then we can see if the reality matches what you would expect.
Your home network and everything connected to it is like a vault
behind your looking lines, valuable information from unencrypted files
containing personal data, the devices that can be hijacked and used for any purpose.
In this video, I will show you how to take
a peek under the covers and see who is talking to what
how to uncover devices or processes that may be sitting down with or if there are
unexpected guests connected to your network.
So we are going to start firstly with
setting our wireless Network Card to monitor mode.
And then with the wireless network adapter in monitor mode, we can start listening
on Wi-fi traffic by running this command, you see in front of you that
we are going to type and explain in depth while we are doing that.
You just go ahead and use the airmon ng command.
And we're going to disable some processes before enabling.
Before putting our interface into monitor mode.
Just go ahead and kill all those processes.
Now, let's put the interface into monitor mode.
So as you can see, our interface is on monitor mode.
You can see of the interface name have changed.
So we are going to use that.
Stopped listening to Wi-fi traffic, so let's write and explore the command
that we have seen previously on the slides.
So to view the Wi-fi networks in the
surrounding area, we can use the airodump ng command start monitoring.
hit enter and we see.
The Wi-fi network.
So for using airodump ng
command later on, start capturing the Wi-fi data that we want.
We might want to take note of the Mac addresses, the ss id
of the targeted network as long as the channel and the S e Ss es ID.
which is the name of the wi fi.
So for the purpose of this video, we are
going to use these Wi-fi name, the channel number 11, and we might want to take.
And note of this Mac address here.
So now we are ready to start collecting data belonging to the target network.
And we can just go ahead now and type the command that we saw earlier in the slides.
So airodump -ng, we are going to use the Mac address.
And we are.
Before typing the Mac address, we are going to use the flag --bssid
space, and then we type the Mac address, as we said we are going to.
Be collecting data on VRV wi fi.
So just go ahead and type the
Mac address of this network then space
dash dash Essid.
Then space, the name of the wifi hear
this case VRV then space dash.
C, and we are going to select the
channels, as we said earlier, which is number 11 on this case,
when we are going to use the flag dash W and we are going to choose.
Directory that we are going to save the collected data, so I'm going to use the
TMP Directory and I am going to choose also like a name,
like an example name that we are going to save the collected data.
Just go ahead and type dash tmp.
We are going to use the tmp directory.
And then we are going to use a name for it.
And then space and then space, and don't forget to type the w lan0mon.
So there you go, you have it, so now you are ready.
To start.
So now we are ready to start collecting
all the data, but you can go ahead and hit under.
So as long as the airodump ng terminal is
running, the data will continue to accumulate.
This terminal you can leave it and running for hours or even days.
So as the command runs, you may want to pay attention on the data section.
So for the purpose of this video, I am using my mobile phone
and I'm connected to the VRV Wireless Network and I am going to go ahead and.
I was a little bit.
And you can see how the data.
We'll be start we'll start sounding more and more.
You can see that this data column.
Showcases how many data packets have been collected so far.
If I have the number of the more
likely it is to discover sensitive information which can be used to.
Further compromise the target.
But when a satisfactory amount of data have been collected,
you can go ahead and stop the session by pressing control and C.
So now there will be a file named cap- data dot.
cap in the TMp Directory,
so these cap file later on can be opened using Wireshark.
So as you saw, there was a lot of
information in the cap file
that we saved, and at first it might appear harmless, but
as we can see, but as we will see in the next video and the later on videos after
inspecting so such packet, you will be able to
learn a lot of information about the target and you can
even reach to a point that you will learn personal information on.
Or the target, so as you saw, we haven't even connected
to the Router and all of these data have been collected.
Just by putting our network interface into monitor mode.
There's no way for victims to know this was happening to them.
So all of these days that can be used by attackers belongs a
nd elaborate and targeted hack against companies and individuals.
So tracking down Wi-fi devices is easy with the right gear,
whenever a Wi-fi network appears where it should, shouldn't or a device starts
connecting to your Wi-fi without permission, many does into the Wireshark.
And of course, having a network adapter can tell you where the signal is
coming from this file, but still makes it easy to determine where a real
access point might be hidden or who might be joining a network without permission.
So, for instance, if you.
So, for instance, if you suspect your
neighbors have been connecting to your Wi-fi network and you haven't been able to
prove it, this technique could provide you with all the evidence that you need.
So there's several ways you can keep your personal data safe from hackers.
And some of those are listed on your screen right now in front of you.
Be very aware of open and public Wi-fi as
you secure browsers always use VPN when you are using
public Wi-fi and protect yourselves with the highest degree that you can.
So I hope you enjoyed this video.
And when you are ready, you can go ahead and click on the next video where you are
going to learn how to Decrypt the Wi-fi traffic that you just captured.
