REQUIREMENTS

(ping me in the comment section if you get any error in installing the fatrat with a screenshot)
After installing fatrat now u should change your kali machine to use JAVA 8 by default because in JAVA 10 we cant decompile the APK so to change it to JAVA 8 use the following command:

update-alternatives --config java

Note - Not all apk files will work with these you need to try many variants to successfully embed your backdoor.

Now, run a fat rat tool by typing fat in your terminal and after entering into the fatrat tool, use the option backdooring original apk.

Now, set your LHOST to your IP address and LPORT I prefer 8080. Choose your path where apk file is stored press enter and select the payload you need to choose and the method you need to embed your backdoor to apk file. Choose whether you need to modify the apk file or keep the original file I prefer not to change the file and press enter. Now thefatrat starts to embed your backdoor with the apk. After finishing, use msfconsole and send the apk file to the victim and wait for the reverse connection.
