Hack Demonstration: We brought a mobile device to demonstrate the hack which is already affected and installed with a malicious app. When the victim user (or) the owner of the mobile phone runs the malicious application it enables the ADB on port 5555 and we can access the mobile wirelessly when connected to the same Wi-Fi network. The malicious application installed on the mobile phone does the following things:
- Makes a backup of all call logs, SMS and contacts and stores them at a pre-defined location on the mobile storage. Once the access to the mobile phone is established we have showcased all of these details on the screen.
- We also remotely opened and accessed Swiggy (Food Delivery Application) remotely and using some ADB commands, we are able to perform tap gestures and we are able to place an order on behalf of the victim user remotely without having to touch the phone.
