In this lecture we're going to learn how to generate an undetectable backdoor about her is just a file
that when executed on the target computer it will give us full access to that computer.
So it'll basically allow us to hack it and do anything that we want on that computer.
There is a number of ways to generate back doors and what we're interested in is to generate a backdoor
that is not detectable by antivirus programs.
Now this is not very hard to achieve as you'll see.
And we're going to do this using a tool called vild framework.
Now I already have villes project page open and here I'm going to include its link in the resources
of the lecture on the top left.
Now if you're not familiar with good this is a version control system that allows programmers to host
share and update their programs.
So to download something from get help all you have to do is click on the green button in here.
Copy this link and then go to terminal navigate to the location where you want to download this project.
And in this example I want to go to all Petey this is a directory where you should be installing optional
software.
If I do ls you will see I only have one directory in here called Keith so to download the bill and here
all you have to do is first of all right the get command which is good.
And what we want to do is we want to clone a repository and the link for this repository is the links
that were copied in here from the green button.
So I'm just going to paste it here.
So a very very simple command we're using get to download a repository from Get we're saying that I
want to clone this repository and the link of the repository that I want to clone is this one.
So if I hit Enter now you'll see it's going to download it for me.
And once it's done if we do you will see we have a new directory called Bill and we can navigate to
this directory by doing she Divell and in here if I list you'll see we have a number of files but the
main file for the program is this one.
Well dot why.
But we can't run this file right now because we still didn't install this tool.
Now Villere relies on a large number of libraries and a third party programs.
So you're going to have to install all of these first before you can use it.
Now luckily you don't have to do this manually because Bill comes with an installation script.
Now the script is placed in the config directory.
So we have to navigate in this directory first.
So Will do you the config and if we list here you'll see we have a file called set up dot SH now as
the name suggests if you're on this file it will install all the needed libraries.
And third party applications that Bill uses so to run an SH or abash file from the terminal.
All you have to do is type that forward slash followed by the file name.
And in our case it's called set up that sh.
Now you can run the set up as is like this but I want to add two arguments to this.
The first argument that I want to add is the dash dash silent.
This argument will run the installer as an unattended installer.
So basically it will install everything with its default settings and it won't ask cause to configure
anything.
The next argument that I want to add is the dash dash force so that in case you're running this a second
time if you already installed fail and something went wrong and you're installing it again the fourth
argument will override any existing installations.
Now I didn't just figure out these arguments myself.
If you actually read the description here on the project page you'll learn exactly how to install it
and what each of these arguments do.
So I'm going to hit Enter NOW and as you can see now it's going to automatically gather information
about my current operating system.
It's going to install the needed libraries and the needed applications.
This might take some time because it's going to download a lot of packages.
So please be patient and give it its time.
Now I'm going to post the video because this is going to take some time and I'll continue recording.
Once it's done.
So right now as you can see the installation is finished and it's telling me that everything is done
so I can run the tool now.
But what I'm actually going to do is I'm going to first close this terminal window and open a new window
just to show you how you would start it by default.
Because usually when you open terminal you'll actually be in the root directory.
So if I do PWT right now you'll see I am in route.
So in order to run fail we have to first navigate to the location where you downloaded it and we downloaded
it to the opiated directory.
So we're going to do cd all pretty well now if we do.
Elias you'll see we have the file that I told you that's the file for the program and we have the config
directory where we were and where we were on the installer.
Now we've already installed everything.
So we don't need to run the installer to run they'll all we have to do is type 2 it forward slash followed
by the program name which is the old UI.
I'm going to hit enter.
And as you can see the program is working with no issues at all.
Now in the next lectures I'm going to show you how to use this program to generate undetectible back
doors that can be used to hack Windows computers.
