Experts from security firm Bkav have identified a vulnerability in Viber – the popular application that allows users to make calls, send text messages and photos for free. The security hole could be exploited to bypass the lock screen on Android smartphones and gain full access to the device. According to the figures from Viber’s website and Google Play, as many as 100 million users might be impacted by the issue.

Attack works in three main steps:
1- Send a Viber message to the victim.
2- Make the Viber keyboard appear on the targeted device by performing some actions with message pop-ups.
3- Once the keyboard has appeared, a missed call must be created or the “Back” button must be pressed.

The lock screen should be unlocked, in order to give the attacker complete access to the vulnerable device. <more>
