According to government officials, the attack took place in the autumn of 2020 but was discovered this month by Parliament's IT staff. The investigation into the case has already been undertaken by the Finnish police.
According to the allegations made so far about the attack, the hackers most likely invaded the systems of parliament either to steal information that other countries will use or to harm Finland.
"The theft has affected more than one person, but unfortunately, we can not say the exact number until the current preliminary investigation is completed", Said the officer.
Police also said that "there is international research cooperation", But did not provide further details.
Norway had revealed a similar incident
Days ago, after a month-long investigation, the Norwegian Police Secret Service (PST) attributed the invasion to the hacking team APT28. This group is said to be associated with the Russian military intelligence service, GRU.
