‫Another powerful and easy to use tool is the fat rat.
‫It's an exploitation tool that can help you to generate back doors and post exploitation attacks like
‫browser attack deal files.
‫This tool compiles malware with popular payloads, and then the compiled malware can be executed on
‫Windows, Linux, Mac, OS X and Android.
‫Because it's not embedded into Calley.
‫We need to install the fat rat first.
‫At the beginning, we need to download the files of the fat rat framework.
‫Clone, the get a account of the fat rat for this purpose.
‫Wait, until the cloning is finished, that may take some time, according to your internet connection
‫speed.
‫The files are cloned under the Fat Cat folder.
‫Go into the folder using the CD command.
‫Look at the files using is let's run the fat rat shell script.
‫Oops.
‫Permission denied.
‫Look at the file permissions.
‫Probably it does not have the executive privileges.
‫True.
‫No.
‫Execute right at all.
‫Make the fat rat file executable using C-H mode that C mode.
‫Linux Command.
‫Now it has execute rights for all.
‫Now we can run the fat rat script.
‫It says we have to run set up Dot S.H. script first.
‫We're not going to run set up as each script all the time.
‫It's just needed to run before the first usage.
‫Like the fat rat file set up, Dot P y file does not have execute privileges, make it executable as
‫well and run.
‫It installs all the dependent tools necessary for the fat rat tool and upgrades the tools.
‫There are a lot of tools that the set up script checks if they are installed and up to date.
‫So be patient.
‫Don't be anxious.
‫Installing tool dependencies.
‫Updating Cally Repo.
‫Installing M.W. 32 compiler.
‫At the end of the setup, it asks if you want a shortcut for fat rat in the system.
‫That means the setup will add fat rat into the path, so you'll be able to run it from anywhere in your
‫terminal.
‫Now we can run the fat rat script.
‫It checks all the dependencies at the beginning.
‫It warns us not to upload the output files to VirusTotal.
‫We already know the reason.
‫It shares the files with the antivirus companies.
‫Instead, you can upload it to know distribute icon to test if it can bypass the antivirus systems.
‫Now we're ready to use the fat rat.
