Since the beginning of Russian aggression, hacker groups, supported by Russian special services, have inflicted about 7,000 cyber attacks on Ukrainian servers and state websites, an expert on cyber security of the Center for Army Studies, Conversion and Disarmament Sergei Radkevich told a news conference in Kyiv on May 10.

"For instance, an attack on the servers of the Central Election Commission during the presidential election of Petro Poroshenko," Radkevich said.

Moreover, Russia conducted a cyber attack on Ukraine's infrastructure power facilities, which led to a large-scale power outage. In Prykarpattya, Kyiv and Chernivtsi regions, about 220,000 people were left without electricity.

“The power system of our country has been seriously damaged. The total power under-supply was 73 MW / h or 0.015% of the Ukraine's consumption daily volume,” the expert said.

In 2016, state sites and resources were hacked - namely the websites of the Ministry of Finance and the Treasury. The attacks resulted in delayed budgetary payments. Then the Cabinet allocated 80 million UAH for "patching these holes."

According to the expert on cyber security, the Russian FSB turns a blind eye to the activities of black hackers who work both for them and also engaged in cybercrimes "under the roof" of special services.

The US is subjected to cyber attacks as well

Notably, the black hackers also harm the United States of America. Almost every day the state faces serious incidents in the cyberspace and is forced to resist "the growing diversity of the latest threats". Director of the National Security Agency Mike Rogers, speaking on May 9 in the Senate Armed Services Committee, said that the United States do not fully understand how to repel the cyber attacks of Russia and China.

"The United States is lagging behind in repelling cyber attacks and still does not have a well-defined cyber policy," Voice of America reported, citing Rogers.

Speaking of Russia, Rogers said that the US needs to "publicly expose this behavior" and strengthen cyber defense systems to prevent further cyber attacks. According to him, it is very important to convey to potential hackers what "payback " is waiting for them.

Senator John McCain recalled that in the past he had already expressed concern about the lack of a policy in the field of cyber security. The Trump administration promised to develop it within 90 days. The time has passed, but there is no strategy.

"Our country is still dismally ill-prepared to deal with such threats," McCain said.

Allegedly, last year Russia organized a hacker operation aiming to influence the outcome of the presidential elections in the United States. The Senate, the House of Representatives and the FBI are investigating the case of Russian interference in the elections.
