Polish Prime Minister Donald Tusk today denounced a cyberattack against his party, which he attributed to a “foreign intervention” in the face of the May 18th presidential election.

“A cyberattack has targeted the Computer System” by the Party Political Platform, Tusk said in a post on X.

“Foreign intervention in the elections has begun,” he continued, adding that “security services show a source to the east.”

Polish authorities, faithful allies of neighboring Ukraine, warned in recent months that Moscow may try to intervene in the next month’s elections by resorting to cyberattacks and misinformation. Poland often accuses Russia of conducting hybrid attacks and orchestrated sabotage on its territory.

Donald Tusk’s head of the office, John Grabiets, made a speech in today’s statements to Poland Rar’s Public News Agency on what happened on the political platform for one “Attempts to take control of computers of party workers and electoral staff”.

He did not clarify whether this cyberattack is ongoing.

“State agencies are working intensively in the cyber security incident of the political platform. The case is serious’ He wrote in a message to X Minister of Digital Policy Christof Gavkovsky.

Warsaw Mayor Rafal Transkovsky, a nominee for Poland’s presidency by Donald Tusk’s party, is currently the favorite to replace the outgoing leader of the Polish state, conservative Andrei Dunda.

But he should face both the harsh nationalists and far -right candidates who express reservations about the issue of Ukraine.
