The United States and Britain have blamed Russia for recent cyberattacks targeting Ukraine.

US Deputy National Security Advisor for Cyber and Emerging Technology Anne Neuberger said, "We believe that the Russian government is responsible for wide-scale cyberattacks on Ukrainian banks this week."

Neuberger described the attacks as a DDoS attack that overloads online services.

She said the US has technical information that the Russian Main Intelligence Directorate, known as GRU, "was seen transmitting high volumes of communications to Ukraine-based IP addresses and domains."

Neuberger added that the latest cyberattacks had limited impact thanks to Kyiv's swift response. She said Russia could be laying the groundwork for "more disruptive cyberattacks accompanying a potential further invasion of Ukraine's sovereign territory."

Britain also accused Russia's GRU of involvement in the cyberattacks on Ukrainian financial institutions.

A British Foreign Office spokesperson said the attacks "showed a continued disregard for Ukrainian sovereignty." The spokesperson added that "this activity is yet another example of Russia's aggressive acts against Ukraine."
