Overall, Viber is a pretty useful app. In my limited experience, I’ve used it to chat and trade photos with friends across the country via Wi-Fi. Basically, it allows users to make traditional phone calls, send text messages and share photos and their location with anyone worldwide; quite similar to Skype but minus video chatting.
Posted yesterday by Bkav Internet Security’s YouTube account, BkavCorp, a security vulnerability in the app shows how the app is not quite so valuable — in fact, the glitch in the system is downright threatening for your Android mobile device.
When someone receives a message while their lock screen is in place, Viber allows a pop-up alert to appear. Nothing weird there but as you can see in the video below, the message gets right passed the security lock screen. This will allow access to the entire rest of the phone: e-mails, contacts and other applications, as well as personal files and saved data. And in the wrong hands, well, we’re all aware of what can result from that type of private access.
Viber is available for every mobile OS and has been downloaded over 100 million times across iOS, Android, BlackBerry OS, WP8, Nokia and Bada. However, the issue was only discovered on Android, on a Samsung Galaxy S II to be exact. Though the company has discovered the same results on Sony and HTC devices as well.
The company has apparently spoken up about the exploit and is working on fixing it.

A company representative commented on this article, explaining how Viber assessed the issue and fixed the vulnerability promptly after this story reached the general public. They have released a “fixed version” of the Viber app sans this security glitch, available for download here.
Also, Viber is making sure that problems such as these will not reoccur in the future. If there are any comments, questions or concerns, the company can be reached via e-mail at firstname.lastname@example.org.
