Hello everyone and welcome to the section. Number 3, cold environment
preparation. Here. We are starting
our open source intelligence Hands-On. Part
of the course. I believe you are ready to start this section of
the course. After the theoretical agenda. We went through
in the last videos, this section only consists of
two videos, but you will shortly, see that
they are not to take for an easy matter to
Or to discuss. The first one is called, configuring
osint virtual machine where we will do a
hardware configuration of our virtual machine. And
in the second one called configuring OST, operating system.
We will do a software configuration of are installed
operating system. I will spoil a little
bit. Now, the operating system that we
will cover in this context of Open Source, intelligence
is Linux and it is not Kali
Linux as you may have presumed.
Welcome back. Here. We are in our first video Section,
3 called configuring osint virtual machine.
Here. We will download and install or our
virtual machine with its prerequisites. Of course, the
best way would be to have a dedicated physical machine for
doing our ultimate investigations. Still
With a Little Help of virtualization technology.
We can create our dedicated virtual
machine on top of our real Hardware machine and
operating system and use it just like
Dedicated one to be clear with
the terminology before we go concerning software
totalization. We have a hypervisor, a
host and the guest Os or get a rare
guest machine. Now, let's demystify this terms. Virtualization
software is called a hypervisor. In our case.
This will be hypervisor called virtual box.
That is a completely free, virtualization software
from Oracle and it's easy to operate.
There are also different.
Free and paid hypervisor flavors out there like
VMware Workstation or Microsoft hyper-v.
So a host is
called a computer that is the host of the virtualbox. Hypervisor
also, in your case, that
will be your computer with its operating system, in
my case. And in this video, that is a MacBook with
Mac OS, Mojave, operating system
as a site. Just as a side note. I still haven't
upgraded to Catalina because of because of
some
Ups that still don't work on the new Mac OS version
and the last term to the mystifies, the term guest
OS, that is the operating system.
We will install inside or better to say on top of
our computer and virtualbox. So we
are, we will talk about a bun to our osint machine.
That will be the guest OS.
A great thing about virtualization is that you can do all kinds of
things in your virtual machine, like download
viruses, try different configurations, and
break them test programs and visit dangerous
sites. And after that, with the feature called snapshot,
you can simply revert to the
original setting, like nothing happened. There are
a few things to consider before approaching this like for
the machine to be isolated Network wide, so
I can't. So it can't access
Whole store, your real network, but
we will clear all that as we go and configure our
virtual machine. Now, let's download and
install everything that is needed to install and run
our arose. And virtual machine first. Stop is
the virtualization software called virtual box. You
can find that on the site address virtualbox.org.
As you can see. We
are going to fire up our brave browser.
Go to the site, and when you're on the
side,
Go to the download section.
And here you can download the appropriate version of for your computer
operating system as I have mentioned. In
my case that we are talking about the Mac OS.
So I will choose the OS X hosts
version.
Click download and install virtualbox.
Now after the installation and before firing
up virtualbox, we need
to download the Ubuntu operating system image or
the OSI file. You
can easily Google your weight to the Ubuntu download
link. So we're going to do just that.
As you can see, you need to pick the desktop version and download it
just be sure you are on the official, a bomb to web
page, which contains the eyes. So, installation
file, if you're wondering, why am I not
using a security operating system like Kali Linux.
My answer would be. I like, having a
more straightforward and cleaner machine without the pre-built
apps and software that. I'm not familiar with
it. Just gives me better control over my security
and privacy because we need to be very proud.
It when doing our osint investigations, I
also use callanetics just for other purposes. I
definitely encourage you to check it out on the official
Kelly dot org address.
Okay. Now we are ready to fire up our virtualbox here.
It is in my version. I already have
some virtual machine installed. But please disregard
them as you see, they are in the inaccessible because
I use an external disk for their hard drives. That
are not connected to my computer. So
pick new.
Provide the name of the virtual machine will
recall it all sent Ubuntu,
20. Because of the version of
Ubuntu Linux.
I will leave the machine folder default.
But I will change the version of
the operating system.
And since our version is a bun to, I
will choose the Debian 64-bit version.
I didn't choose a bunch of because I found that the virtual machine
works better this way. Also, as a
side note in regard to the machine folder here.
You can pick some other location like your external
disk. If you have a space issue. I always have
that issue. So external drives are great for
that. Just be sure that you are all, just
be sure that all at just
be sure that you're
All external drives are at least usb3
compatible because of the speed virtual
machines hard disk will run from that external disk,
and it needs to be quick.
I seen it typo here.
Again, let's make a Debian.
Okay.
Now, let's choose the memory size which will be dedicated to
the Abundant. Ooh, I usually go with half of
my host memory. So I will choose 4
gigabytes.
That's 4096 megabytes.
For the hard disk choose.
The new the creation of the new one.
As this is a brand new machine and finally, press
create to proceed.
Now, we have to choose the disk properties. I will use
my default location. And instead of the default value
of 8, gigabytes, for the hard drive. I
will use 10 gigabytes.
For storage because the installation requires a little
bit over 8. So 8 is insufficient, of
course, more is always better. If you can put
down at least 20 Gigabytes, but for our
demo, I will use the value of 10 GB, choose
the default options for the hard
disk type and the storage on
the physical disk.
Dynamically allocated means that
the virtual machines disk won't take 10 GB at
once rather than a mclee as it grows, but
with a 10 gigabyte limit.
And press create.
After the creation of our virtual machine template, you
can see it here in virtualbox. It's powered off and
its current state. It is still
clean without the operating system. Now, we have to do
the configuration of the hardware settings of the virtual
machine. So click settings storage
and in the controller
IDE
Load, the previously, downloaded a
bunch of ISO file as the installation media.
And press, okay.
Now it's time to turn on our virtual machine. But just
before we do that, there are a couple of things we
need to do to be more secure from the network perspective. I
recommend for you to use on your host machine,
the real computer a VPN, which should
be always turned on because we
will configure the network settings of our virtual machine, in
a way that it uses the hosts Network through net,
or network address translation this
Means when I have VPN turned on prior to starting
the machine, it will use the VPN of my
host and that is a good thing. Since we do not wish to
use our ocean machine, on our real home / office
Network.
As you can see, my VPN is
on. I previously mentioned 2. Vpns Rotom,
VPN and app, secures freedom.
You just to check the settings. The network settings
of the machine. Are we using that? Yes, that's
okay.
And another thing for the convenience part, let's
create a shared folder between the guest
OS and the host machine. So we can be more efficiently moving
files. Between two.
Select settings. Check the advanced.
So we can be more efficient in Drag and dropping and
with the shared clipboard.
Bi-directional choose the shred Clipper to be bi-directional.
Also, drag-and-drop to be bi-directional and
in the share folders tab add.
With the plus sign. A new folder path.
Other.
I'll create a new folder.
Call it.
Us into bun. 220 share.
You that?
Make it out of Mount.
And okay.
This is just the preparation for the shared shared
folder configuration because
we will finish up the configuration when we install Ubuntu.
Now, let's fire up our virtual
machine, select the correct virtual
machine and press start.
Here it is.
You can disregard this messages.
Now, the configuration installation is checking disks.
We can, we can skip
this, but I always leave it to check it, to
check it, check the file system.
Okay. Now we are at our first install screen, the
welcome screen where we can choose our installation language.
I will choose English because actually,
I wouldn't wouldn't recommend taking
some other from personal experience. If
I take my let's say, domestic hrvatski Croatian,
language, when I come to
a problem. I try to Google it. I
have a lot of difficulties to solve
the
Because the problem is,
I have to translate the problem, and sometimes
the simple as
that words doesn't match. The translation is not
good. So we have an option to try a
bun to or install Ubuntu. We
arranged, we decided prior
to this installation, that we will install a
bun, to on the newly created virtual machine. So
press install.
pick the,
Default keyboard layout. We will add that
later on.
As you can see, we can, we
will pick the normal installation. And since
we have the connection to the internet and
we will allow a bun to to download updates since we
have internet access. And also we will
pick to install third-party software for graphics and Wi-Fi
hired hardware, and digital media
format.
And press continue.
Yes, we will erase disk and install Ubuntu.
Install now.
Confirm, the changes.
So this is a virtual disk. You don't have to be afraid, if
something goes wrong.
You can always revert start over or something.
You have to choose the
appropriate time zone.
So we have to provide an account name.
Will say my
name is osint.
My computer name will be.
Hosted a bun, too.
My username will be osint. Also, and
I will choose a password.
And so the installation begins depending
on the speed of your computer, your discs. This
could take a few minutes.
We are almost there with
the copying. Now. We are installing.
Also, don't forget that we have selected to
download the updates and apply them. So
this also depends on your internet
collection cook. This
also depends on your internet connection.
When distillation is complete. Click restart now?
And yes, don't forget to remove the installation medium.
Will do that right away.
I usually turn off the machine power off.
and remove the
medium.
In the storage area.
Completely.
Because I do not need it anymore.
I see that it is empty. So
that's fine. Okay, and
start the machine again.
Here is our the boot up installation screen.
Here is our, after the installation. Here's our
boot screen.
We wrote down our login information previously. So
that wouldn't be a problem. Actually, I had a
seat. I had few situations where I needed to create a virtual
machine quickly. And when I, when I was done
with the installation, I just simply could not
remember the login. So that
could be avoided. If you write it
down.
For the default online accounts, press skip.
Next. Would you like to send this information? No,
do not send System Info. Next.
Do not, we will not choose the
location services.
And press done.
If you get prompted to install updates, be
free to click. Remind me later.
So now we have a function in virtual machine
that contains the basic programs for everyday usage
and for you to serve the internet. And
as you may remember, it is
currently using the VPN of our host machine.
So we do not need to bother with
the network, a privacy in that context.
No, just do a couple of things before we
continue to our next video Lesson, where we
will configure the operating system. We will
have to fully make use of power virtual machine.
We should install virtualbox has guest additions
software. This will
allow us to have better resolution, make the
use of copy paste options from the host to
the abun to Virtual Machine and
other
Conveniences.
We have to go to the virtualbox menu, selected
devices and select
insert guest additions CD image.
Click run to start.
And put in the password.
Allow the process to complete.
Again, with the password.
If this happens, be free to say,
yes.
Now, we need to restart the VM.
Now that we are logged back, then we
can check our the virtualbox guest additions
installed correctly. We
can test or you can test this by resizing the
screen.
If you make, if the screen resizes correctly, that
means it is functioning.
If something went wrong with
the resizing, that means that you
do not have installed. You didn't install, the guest
additions correctly. So you can repeat
the whole process again.
Now, you can be free to shutdown the
VM our Ubuntu.
And after we power it off, we will just check is
the shared clipboard and drag-drop options,
set correctly. We did them, but
just to check.
Yes, short clip art is bi-directional drag-and-drop bi-directional.
And the shared folders. Yes.
It is set correctly because we will
do some configuration in the next lesson when
we when we access our operating system.
Okay, we downloaded installed and
done the hardware part of virtualization with the
virtualbox and the Ubuntu operating system installation itself.
In the next video. We will configure our osint operating
system so we can use it fully as a nose into
investigation machine. We will configure our privacy
options computer management configure
browsers and missing libraries apps
and so forth. So see you in the next video.
