Title: Viber Communication Security - unscramble the scrambled Author: Michiel Appelman, Jeffrey Bosma and Gerrie Veerman Source: SNE/OS3 Date Published: 24th December 2011 '....In the past couple of years more and more communications which used to use the regular mobile operator networks started moving towards ip-based networks. This has given rise to ‘apps’ on smartphones that enable consumers to connect to each other without the use of their mobile operator. More recently the security implications of switching from the closed network of the operator to the open Internet have become apparent after some ‘apps’ have shown severe weaknesses. In this project we will take a look at one app in particular: Viber, a voip application used on cellphones. The report tries to answer the question how Viber performs — security-wise — in comparison to other services. A definitive conclusion has not been found but most details of the protocol used to transfer the voice data have been documented. The application code has been analyzed but no real weaknesses were found. This lack of weaknesses found doesn’t mean that the app is secure, due to limited time and experience of the authors a lot of investigation is still to be done......' https://www.os3.nl/_media/2011-2012/students/jeffrey_bosma/ssn_report.pdf Haven’t read it yet.

Thanks guys, I sent an email to Viber and I haven't received any responses from them. Nathan is there any chances you or your colleagues test it and publish the result? Because it so popular amongst the Iranian activists. Thanks, A On 21 September 2012 01:04, Eric S Johnson <[email protected]> wrote: Popular in Ethiopia too (where I was, last week).

Hey LibTech, At this time, Viber (http://www.viber.com/) is so popular amongst the Iranian people and it is one of the popular communication ways in Iran. I was wondering to know this app is secure or not? The data is encrypted or not?
