WARSAW, Jan ⁠15 (Reuters) - There ⁠are ‍strong reasons to believe a group connected to Russian ‍secret services was behind a December ​cyberattack on Poland's energy infrastructure, Polish Prime ​Minister Donald Tusk said on Thursday.

Poland's power system faced its largest cyberattack in years in ​the last week of December, its energy minister Milosz Motyka ​said on Tuesday.

Tusk added that because Poland's defence ‌systems worked well the attack did not threaten critical infrastructure and ​had practically no ⁠negative consequences.

"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.

"I want ‍to say that Poland defended itself against attempts at destabilization, ⁠and its infrastructure was never threatened for a moment."
