It's mostly not actual leaks though. Just result of countless government beuracrats working for $300 / month. Considering fact that some people going to die on frontlines for $3000 / month leaking bunch of data for $100 is no brainer.

To give an example. Since authoritarian regime like databases every hospital have to put data about every appointment or vaccination into regional online database. So every single doctor, technicial or their friend have names, national insurance ID, home adress and passport data for every single person who ever used medical services in that region.

And since every phone number at least supposed to be registered on passport data it's super easy to connect any other non-government data leaks to specific person.
