On Friday, Deputy National Security Adviser for Cyber and Emerging Technology Anne Neuberger said that the Biden administration believed Russian cyber actors had recently targeted Ukrainian government entities, including the country's defense ministry.
"We categorically reject the unfounded statements of the [US] administration and stress that Russia was not involved in the mentioned events and has not conducted any malicious operation in cyberspace," the embassy wrote on its Twitter page.
The diplomatic mission described the remarks of Neuberger as anti-Russian.
In her briefing, Neuberger said that the US has shared cyber intelligence with Ukraine and its European partners, accusing Russia of allegedly being behind the latest cyberattack on major Ukrainian banks. According to the adviser, the Biden administration is prepared to respond to future Russian asymmetric activities, such as cyber strikes against the US or its allies.
Russia is being accused by the US and its NATO allies of planning a military "invasion" of Ukraine. Moscow has repeatedly dismissed such allegations as nonsense, pointing, in return, to the alliance's growing military activities near Russian borders and warning the West against supporting provocations by Kiev.
