What is it ?

PEGASUS (SPYWARE) : Pegasus is spyware that can be installed on devices running certain versions of iOS, Apple’s mobile operating system and android devices, developed by the Israeli cyberarms
firm, NSO Group.


The Spyware is transmitted by calling the target phone on WhatsApp.The Spyware enters the phone even if the call is not answered. According to some reports, the log of that call gets erased. According to The Citizens Lab of the University of Toronto, which worked with WhatsApp on identifying spyware victims, this is only one of the ways of delivering Pegasus. It notes several other cases such as alarming SMS that prompt targets to click on a link .
