Each WhatsApp profile is synchronized with Contact List of the device (smartphone, PC or tablet) it is installed on. This is being done for transferring the contact list to the application to facilitate the communication process. In turn, WhatsApp account transfers the backup copy to the server to save the data further. This data may be required for further account transfer or phone number changes.
WhaSpy uses the SS7 vulnerability to intercept an incoming data packet with a QR code. Having done this, the application transfers an account to your Dashboard, where you can find all the information from the backup copy. Information is sorted into sections for ease of visualization on your Dashboard. You can also download the archive to the device’s hard drive for further research and processing.
