HACKING THE MESSENGER
An attacker can merely ring a target phone through a WhatsApp call. It need not be answered, meaning a so-called missed call would work as a hack. The call would often disappear from logs.
The problem was first reported by a UK-based lawyer who noticed suspicious calls on WhatsApp and approached researchers. WhatsApp said it separately too found the flaw.
Reports said the spyware belonged to Israeli company NSO Group, and carried references to Pegasus – NSO’s flagship product that spies using microphone, camera.
