In this lecture, we're going to learn how to generate an undetectable backdoor abductor is just a file
that's 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
vill framework.
Now, first of all, we're going to have to install this framework.
There is an installation script in the resources of the structure that you can use to automatically
install it and configure it properly.
I already have it downloaded right here in my downloads.
As you can see right here.
It's called installed Bill.
So I'm simply going to open up my terminal and I'm going to navigate to my downloads using the CD command.
So she downloads and if we do, unless we can see this file right here, the installation script, by
the way, feel free to double click it and see the contents of it.
It simply has a number of commands to install dependencies, download vill and configure it properly.
So to run this script, first of all, we have to change its permissions to an executable.
And to do that, we're going to use the chmod command.
We're going to do plus X to add executable permissions and the file that we need to add executable permissions
to is this file right here, this file right here, it's called install bill.
So we're basically using the of command to change permissions were at an executable permissions to this
specific file.
We're going to hit enter and the commands run with no errors.
That means the command got executed properly.
So if we do this again to list files, you'll see the file listed in green, meaning it is an executable
and to run an executable and Linux, we always do it forward slash followed by the executable name.
So I'm just going to type I n tab to autocomplete and we have the name right here.
So we're simply running this file as an executable by adding that forward slash to it.
And I'm going to hit enter to run it.
I'm going to maximize this.
And you want to give this.
It's time.
You want to make sure that you have Internet access because as I said, it can download and install
it and will is a huge framework.
That's why I actually didn't include it in the custom image, because it's really, really big.
So you want to give it this time, make sure you have stable Internet connection so it's able to download
and install everything.
And if you face any issues, just take a screenshot of the error, post it in the Q&A or in the forums,
and we will be happy to help you.
Now, I'm going to post this video and we'll resume once the installation is complete.
Now, you might get this message during the installation, as can you, if it should automatically restart
services during the upgrade and during the install.
We're going to navigate with the left arrow, hover over the years and hit the enter key on the keyboard
to say yes and continue the installation.
Now, during the installation, you might actually get messages on the terminal telling you to go through
a prompt and click next.
Next, next, ignore them.
You don't need to do anything.
The script will do everything for you.
So you literally need to just wait for it to do everything.
And that's about it.
Perfect.
Now the installation is complete.
I'm just going to clear the screen, and if we just type the tool name L hit enter, you'll see that
the program will run with no issues at all.
Now, in the next lectures, I'm going to show you how to use this program to generate undetectable
back doors that can be used to hack windows computers.
