Hackers broke into railway frequencies to disrupt traffic in the north-west of the country overnight, the Polish Press Agency (PAP) reported on Saturday.
The signals were interspersed with recording of Russia's national anthem and a speech by President Vladimir Putin, the report says.
Poland is a major transit hub for Western weapons being sent to Ukraine."
