As measures of retaliation for Russian cyber attacks, US National Intelligence, the CIA, the National Security Agency (NSA) and Pentagon have suggested, in particular, on "blocking of secret bank accounts of trustees of higher Russian leadership in Europe and Asia", as well as using of unilateral sanctions to limit the movement of Russian Intelligence leadership across the world.
It is reported by The New York Times, citing sources.
One of the interlocutors also spoke about the idea of revealing the Putin's links with oligarchs." Although this idea was eventually declined as other people thought it would not shock the Russians, he said.
We recall, US President Barack Obama has promised the Russian Federation a "clear answer" for cyber attacks which affected the outcome of elections in the United States. In particular, it can be both public and non-public measures. He stressed that he has no doubt that Russia stands behind the hacker attacks on the servers of Democratic Party and US institutions.
Convincing evidence about cyber attacks to the country were provided by intelligence officials. In addition, Obama said that cyber attacks could be carried out without the knowledge of President Vladimir Putin. The US president said that he had asked him to stop them in September during a meeting at the summit of G20.
