However, there have been a number of bugs in the past, for example see Viber begins fixing image-encryption vulnerability. Viber messages are supposed to be encrypted. It explains some concepts (protocol,'encryption/scrambling', etc.)Īpart from that there were many spy plugins available to detect it ,Apart from above have a look over here detailed tutorial how system adminstrator will spy over uĪ network administrator will be (probably) be able to see there is traffic to Viber. Please read the following paper regarding viber security. HINT: wifi monitoring mode (see wiki) is not supported on Windows with WinPcap, so if you want to capture the wifi/wlan traffic of your android phones you either have to use a special adapter on Windows (AirPcap) or use Linux as the platform for Wireshark. Anyway, you will see how far you get, as soon as your wlan/wifi capture setup works. Unfortunately both issues (own protocol and encryption) will make it hard/impossible to extract any valuable information from the captured packets. I don't know for sure, but I'm pretty confident, that they will use their own protocol and I hope they will use encryption, otherwise I would consider a security failure and not a service -). Well, even if see the wifi/wlan traffic of the phones, you may not be able to capture 'voip' calls made via. I am NOT able to detect the VoIP call being made on these smartphones (using the smartphone app Viber). Please read the wiki about capturing traffic in such an environment: It could be achieved using special plugin :įrom wireshark forum Capture setup is possibly not ready for wifi/wlan capturing.
