Viber 6.0 for iOS security features teaser 001

Two weeks after rival WhatsApp announced that chats on its platform are protected from eavesdropping with end-to-end encryption, the popular messaging app Viber on Tuesday released a privacy-enhanced edition of its iPhone and iPad app.

Bumped to version 6.0, messages you send and receive through Viber are now protected with end-to-end encryption, as indicated by the new padlock icon, and you can also hide away specific chats.

Encrypted chats

With end-to-end encryption, the contents of your messages are encrypted on the device, servers and during transmission to prevent eavesdropping. End-to-end encryption works with individual messages, as well as with groups and Viber messages on other platforms—assuming everyone runs the latest version of the app.

“We have been working on this for a long time and are proud that our users can confidently use Viber without fear of their messages being intercepted – whether it is in a one-to-one or group message, on a call, on desktop, mobile or tablet,” said Viber.

End-to-end encryption is rolling out globally over the next two weeks. If you see a grey padlock within the app, your copy of Viber has enabled end-to-end encryption and you are secured.

Other tidbits

Swiping a chat in the list reveals a new hidden option that lets you hide away specific chats from the main screen so no one but you knows they even existed.

Viber 6.0 for iOS also includes a Trust Contact feature that adds another layer of security. This ensures that each user has an individual cryptography key associated with their particular device. You can manually mark a Viber contact as “trusted,” which will change the padlock color to green.

A red lock means a problem with the authentication key, which could indicate a benign issue like a user changing their primary phone but also point to a man-in-the-middle-attack or other breach state.

Should that happen to you, simply re-trust a contact and you’ll be safe.

    Nice. Seems the FBI vs Apple conflict really ended up hurting the FBI in the long run.

    WIsh more of my friends used Viber instead of whatsapp, superior service

  • Mr_Coldharbour

    Yet another service which never gave a damn about privacy or encryption, allegedly adds it, now it’s like they invented the whole concept, and other more reputable services like Threema and Signal that only launched because they believe in privacy and encryption never ever get mentioned. A service which didn’t ship/launch with E2EE and was only added later on, means that feature will easily be taken away from you. Also Viber, Whatsapp and the like doesn’t make its money the same way Open Whisper System’s Signal, or Threema does, they still have access to your comms and therefore possess all encryption keys. You’re not in control, they are. I’ll never use Whatsapp or Viber, privacy and encryption is not a core value of theirs.
