Hello Sir,

Could you please confirm the Application and Threat database version of your PAN firewall...?

Is it identifying as an unknown-UDP while initiating a Viber call/text..?

Are you using Viber 3.0.0 on your Android phone...?

Could you please install viber on your laptop and initiate a call/text and let us know if that's identified by PAN firewall?

If the application is showing up as unknown, you can follow the steps in this document to submit Viber to the App-id team for identification.

Hello dat.tran

There is a new issue reported on Viber 4.1.1 version app that it is being identified as unknown-udp. Palo alto team is working on it. Packet captures of application traffic can be taken and shared to palo alto team through a case to better identify the app traffic as it was earlier before. There may be some changes on the way the viber traffic or ports usage and so on. Hence there may be a need to enhance the signature.
