You’ll probably be aware that last week, WhatsApp was at the center of a storm of controversy following the exposure of a major vulnerability in the messaging app.

The security flaw in question leverages what’s known as a ‘buffer overflow’ to give an attacker the ability to install spyware on the target device, and subsequently gain access to a vast swathe of personal data; calls, texts, photos, location and other data on the handset, along with the possibility of activating the phone’s camera and microphone for real-time surveillance activities.

This attack reportedly utilizes spyware known as Pegasus – more on that shortly – which allows your phone could be infected via a simple WhatsApp call, that even more disturbingly, doesn’t even need to be answered.
