Lesson 23 : Introduction To Nmap And Zenmap Video Lecture | Ethical Hacking using Kali Linux (in English) - Software Development

hey guys welcome to the next tutorial
for ethical hacking and penetration
testing we would be doing some practical
live examples and live tests in this
tutorial and this is where the actual
ethical hacking starts and this is yeah
these are the practical things so the
first thing that you need would be you
need to configure your Windows 7 as well
as Kali Linux
I'll just going to open it and make sure
that they both have internet access just
in case yeah just not just in case you
would be needing them and make sure that
you have configured them as the network
as NAT I'll just go and show it to you
make sure that you have NAT and not a
bridge store host only custom lang I
don't want any of these because you
won't be able to connect to internet or
even the land connection that is there
between these two and make sure that
even in Kali Linux has the same and I
just need to go to install the VMware
tools over here which I did not start
this code I install them first okay
I did that in Kali next but over here I
forgot so I'll just couldn't install
make sure that you have all of these
things ready updated Kali Linux and your
windows 7 version and VML tools
installed in both of them typical effect
I'll just install them you know just off
this I don't want any irritating
messages and yeah perfect
so now we would be looking at going
ahead and gathering information once you
have done foot printing and recognizance
I believe you must so I will assume that
you have the IP address by gathering
information about a particular host so
what do you need to do once you have an
IP address how to gather information
about what operating system it is using
and what is the hardware you can get
each and every information just by using
a simple application which these inside
the Cal Linux that it is n map as well
as n map and it's not only for Kali
Linux or wind or Colleen X or Linux this
available for even for Mac as well as
Windows so in case you're using Mac or
MacBook Pro or even Windows I'll just
show you and map for Windows it's called
as Zen map and for yes perfect so this
is the Zen map version which is emmab is
the graphical user interface and nmap is
a command line so I will probably use
both of them to show you how it exactly
works and if you're a beginner being a
beginner I suggest you use ma because it
has a CUDA graphic user interface it
does the same thing but M map is a bit
more better because it is much more
quicker since it is not a good GUI so
here you can go ahead and gather
information here is an intro install
guide and everything you can go ahead
and find over here 6.47 is the latest
and here's install guide is quite simple
for we have it for BSD Solaris Apple
Windows Linux UNIX any operating system
you name and we have it for everything
so yes that would be it so let's check
if I have installed perfect and yes let
me just restart it
as you can see that we have the Zen map
version over here a linux okay
we have n map and for Zen map we have it
over here already installed just let my
computer store and I'll go show you as
to how we can go ahead and gather
information okay perfect so I'll just go
down open my command prompt and assuming
that you have already have the IP
address I'll just go and check ok so now
I have done a loaded lots of foot
printing and I assume that you have the
IP address of this specific person
that's 1 9 2 1 6 8 2 3 6 and 1 3 1 and
let's check the IP address of a vertical
line X and it is IP conflict in your
windows and it's ifconfig in your
colonist or any linux version you're
using so the IP address is 130 and over
here we have 131 so I believe the
Gateway would be a up to 264 into is the
gateway would be the same for this herb
leaf let me check
yeah it is the same for this so perfect
so after I have this I'll just go and
check
hey perfect so what I would be doing is
up now I just have the IP address of my
target machine that is Windows 7 but I
don't know it's Windows 7 I just had the
IP address and server 9 2 1 6 8 2
through 6 and month even so what I would
be doing I would go over here I'll open
my Zen map I'll first go down and show
you the end map so you can go and you
need to go ahead and read all of these
things it can give you much better
information than I can over here it has
all the commands that we need to go
ahead and use the il di RSL to go down
list ping scan and if you're not easy
for if it is if you're not able to find
anything specific over here then it
would be better for you to go ahead and
use the Zen map version just you open
that as well ok so first thing I would
like to check isse I would want to go
ahead and check what is my gateway IP
and which all computers are there and
this gateway IP sauce this type without
now I'll just open a new one and I'll
type ro ute route - space - n so these
are this my gateway IP address 192 168 -
3 6 and 2 that means that and the we
have the same for Kali Linux as well as
my Windows 7 now it is always the same I
just wanted to let you know now I'll
just go ahead and type it over here so
then just in case if you're doing the
man in the middle attack and you don't
have the IP address so let me show you
that is another way to go ahead and
gather the IP address if you are have
the same gateway then you can just type
nmap - s P and 192.168.20.10 let's check
okay st notice issue the hostname let me
check okay yeah sorry it should be small
s in capital P so what I did over here
is that since the IP address will
contain in total of 254 characters or
255 I will be using 254 since I don't
know how much they're a total of
computers these are connected I will
assume that this is my only operating
system and this is not a host operating
system this is the main operating system
I am using it on a PC and I have and
this whole PC would be my router and
this is my another operating system
which is on the same gate wave so what I
would do I will go ahead and scan the
Gateway right now by typing this command
and map SP and I'll open a new one and
I'll show you what the SP command does
okay okay perfect
and map and yes and we have what SP does
is that it gathers all the IP address
that we have from between 1 9 2 1 6 8
point 2 2 1 & 2 1 6 8 2 36.2 254 so I'll
just go to hit enter and let's check
perfect see we have all of this
information so it's showing that there
are a total of four hosts on this and
that it will also be showing my own
version so let me check which is my own
operating system my IP address is 1 9 2
1 6 8 1 30 so this means that this will
be cancelled since since that is the
that is my PC this one I have one more
with the ending with the 254 I will
cancel that as well because I won't be
using that after that because that is
the final one and that is never the IP
address after that we have two things
left and as you know that 2 3 2 2 3 6
point 2 e's my gateway this is the last
one pending which is 0.1 3-1 and which
is the IP address of my windows 7 over
here as you can see so now I need to go
ahead and check if I need to go ahead
and attack this specific PC I need to go
ahead and check what operating system is
using which updates has it installed
whether the Service Pack 1 or not and
depending upon that I can go ahead and
attack that PC so yes that would be it
for this tutorial in the next tutorial
be teaching us how we can go ahead and
attack them and gather much more
information related to them
