Director of National Intelligence (DNI) of the United States Daniel Coats says that Russia will conduct bolder cyber attacks on Ukraine during the next year, using new capabilities.

"We expect that Russia will conduct bolder and more disruptive cyber operations during the next year, most likely using new capabilities against Ukraine. The Russian Government is likely to build on the wide range of operations it is already conducting, including disruption of Ukrainian energy distribution networks, hack-and-leak influence operations, distributed denial-of-service attacks, and false flag operations," Coats said in the statement titled "Worldwide Threat Assessment of the U.S. Intelligence Community," posted on the website of the Senate Armed Services Committee on March 6, 2018.

Speaking about global cyber security, the U.S. intelligence community says that Russia, China, Iran, and North Korea will pose the greatest cyber threats to the United States during the next year.

"These states are using cyber operations as a low-cost tool of statecraft, and we assess that they will work to use cyber operations to achieve strategic objectives unless they face clear repercussions for their cyber operations. Nonstate actors will continue to use cyber operations for financial crime and to enable propaganda and messaging," the statement said.
