How To Change Mac Address In Kali Linux | Macchanger Video Lecture | Get to know Ethical Hacking (English) - Software Development

hey guys hackers Floyd here back again
with another video and welcome back to
the ethical hacking course and in
today's video what I'm going to be
talking about is Mac changing or
changing your MAC address now you might
be asking yourself why is this important
why would I need to change my MAC
address
well basically changing your MAC address
will give you more privacy and will
protect your identity so in a way it's a
form of anonymity however a Mac changing
your MAC address will be effective only
usually it's very effective for local
area networks or Wi-Fi networks so just
your home network or your school network
for example it's really not powerful
when it comes to connecting yourself
over the internet and performing hacks
or performing scans like so
so let's basically get started I'm gonna
explain as we go so like every every
video that we've gone through I'm gonna
start from the terminal and we're going
to use a command called Mac changer Mac
changer and we're gonna say help Mac
change your help right so this is going
to open the manual for Mac changer in
the terminal so if we look at the
commands it's gonna say we have the help
command pretty self-explanatory we then
have the version of the Mac changer we
then have to the show command will which
will basically show us our current MAC
address which is what I want to get to
right now so let's actually let's let's
run that command Mac changer yes all
right
and if I hit that actually hold on what
we have to do now I forgot to tell you
guys is we have to check our our network
interface devices and you can you can
find this by using the ifconfig command
like I've mentioned in previous videos
and what this will basically do let me
just resize this this will basically
show us our network interface devices
and you want to select the current and
network interface device that you're
using and I'm using the Ethernet 0 so
just keep that in mind or just copy
whatever the name of the internet or the
network interface
a card that you're using just copied I
already know mine is gonna be Ethernet
zero if you're using Wi-Fi that's
probably a LAN zero so let's actually
proceed to the next step so I'm gonna
clear the terminal and let's run the
previous command which is Mac changer
help so we can basically have this as a
reference point and let's run the Mac
Mac changer s oops excuse me Mac changer
Mac changer s and then you want to use
your network interface device - Ethernet
zero and I'm gonna hit enter all right
so it's gonna say your current MAC
address and your permanent pack address
no I want to point out one important
thing here many people mistake MAC
addresses for device MAC addresses now
let me explain this MAC address here
belongs to your network interface card
or your network card all right it does
not belong to the computer and I've got
comments saying of good comments saying
that this is your MAC address and people
can you know track you and stuff like
that that's my network MAC address this
is the MAC address that's displayed on
the network and that's what I was
getting to how is a MAC address actually
utilized on a network well a MAC address
will usually provide two things on a on
a network or Wi-Fi network or a local
area network it will provide you the
identity of a machine via the network
interface card now let me explain that
in a MAC address the first three digits
right here as I've highlighted belong to
the manufacturer and if you do a quick
Google search of this this will turn up
a manufacturer's name so you can
actually find the build of the
manufacturer so that's one way of
identifying it the last three digits can
be changed to your will as I will get to
in a few moments that's the the interest
of this video now how can a MAC address
be used on a network well let's say a
systems administrator wants to know the
devices on on the network you basically
finds the names of the devices with the
MAC address so it's really about
identification and it's this magnet
address does not belong to the device it
belongs to the network interface card in
the device that you're using so I just
wanted to clarify that so basically this
is my current map now if I want it to
change one I'm going to go down up into
the manual section here of the help
section and we basically have the a
command which is mostly used most of the
time so it's going to set a random MAC
address
so let's actually try that so I'm gonna
say that's the a command
so let's actually try that so I'm going
to say Mac Mac changer I always get that
typing wrong Mac changer a and we're
gonna select Ethernet zero that's mine
if yours can be Wi-Fi as well no worries
there and I'm gonna hit enter all right
and it's gonna say the current MAC
address is DC and the permanent MAC
address matches this one and it's gonna
give you a new MAC address which is this
one right here and it actually gives you
information about the manufacturer now
we can basically just confirm this by
hitting Mac changer s if the net 0 to
confirm that indeed it has changed and
as you can see here the current one is a
new one and it's different from the
permanent MAC address so it's really
really really cool to see that you can
actually change your MAC address and I'm
gonna explain why this is usually very
powerful on a Wi-Fi network for a local
area network all right so let's say
you're performing a scan on your local
area network right or your Wi-Fi network
if you wanted to basically find the
manufacturer of a device because most of
the time if a performance can't is going
to give you a bunch of random Mac's and
IPS and basically to determine who who
is using that device
you can basically find out the
manufacturer of the network interface
card that's in the device and from there
you can actually get more information so
as you can see it's a really really
powerful tool to stay anonymous on a
Wi-Fi network whether you're performing
scans or you know packet inspection and
start just basically stuff like that so
it's a really really cool cool little
tool you must in fact it's very very
important I would actually recommend
learning it and it's pretty pretty
simple as you can see here it will just
probably take I'm probably gonna cover
everything in this video right now so if
you want to reset it to the permanent
MAC address what you would use is the P
command and I'm gonna show you that
right now so mad Mac changer P and
Ethernet zero and we're gonna hit enter
and if we check Mac changer s internet
zero it's gonna actually return it to
the previous permanent Mac so you
actually know how to change it to a
random one and you can change it back to
the original one you then actually have
another command which you can basically
set you can basically use the r command
which will basically set a fully just a
fully random max will change the
manufacturer kind and that's the
difference between the setting a random
vendor Mac of the same kind will
basically send that week the hardware
model or the manufacturer model the same
one but a different mac address which is
not really powerful this one would be
more powerful using the r command but
you get the idea you then have the L
command which is also pretty cool this
is actually very very very important you
then have the L command which will
basically print the known vendors so
this is just basically a reference for
you to just choose any random
manufacturer so let's actually try that
all right
so Mac Mac changer
I believe it Oh oops whoopsie Daisy
excuse me guys all right so it's gonna
print out the first three digits as I
mentioned that determines the
manufacturer and it's going to give you
the names of the manufacturers so we
have Samsung with Compaq we have d-link
Cisco and you get the idea so you can be
from here you can basically copy and
create your own MAC address based on
this and just leave the other three
digits random which is what I'm getting
to right now as you can see there are a
lot of manufacturers here and actually
have to just use this cool tool to just
go back up here now to just change it to
whatever you want which I would not
recommend for beginners is the EM
command which you get the idea is
basically just using your own
combination and it's pretty
self-explanatory but that's basically it
guys this is one of very important tools
you must be knowing just to make sure
you're safe on the Wi-Fi network and you
can't actually get detected doing
whatever you're doing so yeah that's
pretty pretty awesome guys I hope you
this video helped you guys or if you
liked the video I want please leave a
