Attackers could remotely install surveillance malware on smartphones by simply calling the targeted phone. The WhatsApp call doesn’t even have to be answered and the spyware will erase the call logs from the devise, so the victim won’t be able to trace the attacker back.
This is a buffer overflow vulnerability in WhatsApp VOIP (Voice over Internet Protocol) stack. An attacker would need to call a target and send rigged Secure Real-time Transport Protocol (SRTP) packets to the phone, allowing them to use the memory flaw in WhatsApp’s VOIP function to inject the spyware and control the device.
