South Korea's mobile messenger service KakaoTalk has reportedly been included in the list of services subject to Russia's regulatory authority for telecommunication.

According to Russia's media outlets such as Kommersant on Friday, KakaoTalk and eleven other services were forcibly registered as "information distribution organizations" the previous day by Russia's Federal Service for Supervision of Communications, Information Technology, and Mass Media.

Those services registered as information distribution organizations are obliged to store information on users and messages on Russian territory and to comply with the requirements of Russian security agencies.

Roskomsvoboda, a Russian civic group on digital rights protection, claimed that the Russian Federal Security Service intends to monitor users of the 12 messaging services.

This organization, which opposes internet censorship, was designated by the Kremlin as a "foreign agent," a term used to mean spies in Russia.

The civic group, however, said that it is uncertain whether the listed companies will comply with the requirements.
