The United States is concerned about the cyber-attack on Ukrainian ministries, but does not yet know who is behind it. This was stated on Friday by White House Press Secretary Jen Psaki at a regular briefing for journalists.

“The United States, our allies and partners are concerned about the cyberattack, and U.S. President [Joe Biden] has been informed about it. <…> At the moment we have no data on who committed it, and I cannot provide any specifics [in this regard],” she said.
