Polish Prime Minister Donald Tusk said on Thursday, January 15, 2026, there are strong reasons to believe a group connected to Russian secret services was behind a December cyberattack on Poland’s power grid last month.
“There are many reasons to believe… that they were prepared by groups directly linked to the Russian services, I don’t want to speculate, but I don’t think we have any doubts about the sources of inspiration,” Tusk told a press conference.
