Viber, a popular VoIP app for Android, has run into a bit of a problem. It seems that, with a little work, full access to your device can be had via the app. The video below demonstrates it in detail, but its not something to dismiss.
Through a few sent messages and subsequent action, the app allows the person with your device to access it completely. All the pics, info, contacts and files will be available
just as if it were you. The flaw is within the app, so which device you have means nothing in this scenario.
