WhatsApp Exploit Used to Install Pegasus Spyware

Whatsapp has patched a high-risk vulnerability that allows hackers to remotely install surveillance spyware on mobile devices by simply calling the targeted phone numbers over Whatsapp.

The vulnerability, identified as CVE-2019-3568, can be exploited to install Pegasus Spyware and steal data from targeted mobile devices by placing a WhatsApp call, even when the call is not answered.

According to an advisory published by Facebook, a buffer overflow vulnerability in WhatsApp VOIP stack allows remote attackers to execute arbitrary code on target phones by sending a specially crafted series of SRTCP packets.

Pegasus spyware allows attackers to access an incredible amount of data from victims’ smartphones, including their text messages, emails, WhatsApp messages, contact details, calls record, location, microphone, and camera.

The vulnerability affects all versions of WhatsApp on iOS and Android, except for the latest version, Facebook says: “The issue affects WhatsApp for Android prior to v2.19.134, WhatsApp Business for Android prior to v2.19.44, WhatsApp for iOS prior to v2.19.51, WhatsApp Business for iOS prior to v2.19.51, WhatsApp for Windows Phone prior to v2.18.348, and WhatsApp for Tizen prior to v2.18.15,“.
