According to the head of the Ministry of Communications Nikolai Nikiforov, following the blocking of Telegram, Roskomnadzor may undertake to restrict access to Viber.
The Minister of Communications allowed the blocking of Viber after Telegram
This is a matter for the FSB, because the authority in respect of such specific issues of execution of the order for the provision of encryption keys is the authority of the FSB. If they have problems with the provision of encryption keys, they can also apply to the court and obtain a similar court decision.
Such a scenario is possible provided that the Federal Security Service will experience problems with obtaining encryption keys.
If the FSB can not get the encryption keys, the agency will go to court. And then there will be a similar judicial decision.

Nikiforov noted that now the blocking of Telegram is performed with varying success.
If, however, to digest the essence of the problem, then Viber really can have problems.
Pavel Durov emphasized that the principles of encryption of user correspondence in 2018 do not provide for the transfer of keys to third parties. This is technically impossible, because each message is encrypted on the user’s device.
It turns out that the FSB demands something that it is certainly impossible to provide. At the worst scenario, you can completely re-block all services. [ Izvestia ]
