Russia's main domestic security agency says unspecified foreign special services are plotting a series of cyberattacks aimed at destabilizing the nation's financial system.
National Intelligence Director James Clapper says it appears that a "non-state actor" was behind a massive cyberattack last week that briefly blocked access to websites including Twitter and Netflix.
The rules proposed by the three agencies would pile on a second set of stricter standards for big banks' computer systems that are considered critical to the functioning of the financial industry.
