Extraction from Apple devices is as easy as a simple iTunes backup with no need to jailbreak the device. We currently support Viber for Apple iOS and Android devices. Oxygen Forensic® Detective offers the most comprehensive Viber data extraction from all possible sources. This will also be covered in the second part of our blog. What does this mean for investigators? Even if you have an unlocked phone this does not mean you will see all the conversations in Viber. Once a chat is hidden you need to enter a PIN code in the messenger search field to unhide it. Viber offers users the ability to hide any chat by setting a PIN code for it in the Viber settings. Now let’s look into one more interesting Viber feature that is really unique. We will show you what artifacts can be retrieved in the second part of our post. If a message was deleted for everyone in Viber only partial recovery is obtainable. Unfortunately, once a message is self-destructed it cannot be recovered by forensic software, even if a physical extraction is done.Īlmost every Messenger used today offers the ability to delete a chat for everyone within the sent messages. Secret chats offer self-destruct messages and also screenshot notifications. This method of communication allows users to chat in an encrypted channel that will not be synchronized with the cloud service or with Viber Desktop. However, in comparison with WhatsApp, Viber offers secret chats. Additionally, they state no data is stored on the Viber server and that messages are only temporarily stored when they cannot be delivered to the mobile device.Public chats on Viber are not encrypted at all. Viber’s official website states the app offers end-to-end encryption and the encryption keys only exist on user’s devices. According to Statista, there were over 1.1 billion registered users as of March 2019. Initially the messenger was developed in 2010 by the Israel-based Viber Media, which was then bought by Rakuten in 2014. The software app is provided as freeware for Android, Apple iOS, Microsoft Windows, macOS and Linux platforms. Viber is a cross-platform voice over IP and instant messaging software operated by Rakuten.
