How to Hack Someone's WhatsApp with Mac Address of the Target Devices Let's See This Artical



In which we will need the MAC address of the target mobile, BusyBox app and Terminal emulator app. You can download both the BusyBox and the Terminal emulator from the Google Play Store. With these three necessities at hand, we can now proceed.

Step 1: Using your smartphone, download, install, and run the BusyBox app. You will be required to create an account.

Step 2: Take the target mobile phone and obtain its MAC address. Follow these steps to you get the MAC address “Settings> About Phone> Status> MAC Address. Write this address down as you are going to need it.

Step 3: Launch the Terminal App and type $ su and press "Enter".

Step 4: In the next step, type "$ busybox iplink show eth0" and hit "Enter".
NOTE: If you get a "device not found" message, enter wlan0 instead of eth0 in the spaces provided.

Step 5: In the next step, type "$ busybox ifconfig eth0 hw ether" followed by your MAC address. type your victim's MAC Address XX:XX:XX:XX:XX:XX
NOTE: You have now successfully spoofed your MAC address. You can confirm this by entering the following command "$ busybox iplink show eth0".

Step 6: Launch your WhatsApp and enter the phone number of the target WhatsApp account.

Step 7: Before you can completely hack the victim's WhatsApp you will be required to confirm the hack. In this case, choose call verification.

Step 8: Write down the code that you will receive and enter it into the box provided on your smartphone.

It is simple as that. From this point henceforth, you will be receiving each and every message that leaves and enters the target phone WhatsApp account
