fico is extremely against Ukraine and its president, and correspondingly extremely pro-russian to the point of being their lapdog. Their entire government is just a clownshow full or properly primitive incompetent people that make an average MAGA an elite intellectual in comparison, and openly racist/xenophobic extreme right wing bordering neo nazis types (I wonder why those types end up being traitors/collaborators with russians also in other places, I guess easiest group to manipulate/bribe).

That they throw guilt on Ukraine doesn't mean anything at all since its all politics to shift blame anywhere but their own incompetency, especially without specific proofs provided (for which there aren't any even 18 months after the crime).

You do a comparison with the up to date papers. It just takes ages.

The involved parties and the notaries keep copies of every transaction.

Property is not fluid and doesn't change hands very often. Sure, in a large enough market lots of activity happens every day, but any given property is only involved in a transaction once a decade. You can have very old backups and still capture the state of the market to 99%+. Any recent activity will have brokers, buyers, and sellers, who all have current copies of their activity.

Also, this sort of event should result in some hackers being found and jailed for life as well as their families being bankrupted permanently. Or, if they are being protected by their government, this should be considered an act of war and an appropriate military response should be delivered.
