The same thing happened to Slovakia not that long ago.

Apparently tied to Ukraine in this case.
The Slovak land register was hacked in January 2025. Hackers uknown encrypted the database, asking for an undisclosed 7-figure amount as ransom.
The whole country's real estate market was paralyzed for about a month. It took couple of months to restore everything from backups and paper agenda and resume normal operation of the land register office.
It was the largest cyber attack in Slovakia's history. The authorities to this day haven't provided any information on who might be behind it. The investigation is still ongoing. Several government figures including the PM were however very eager to immediately point on Ukraine, without any sort of proof.
