Please read the article linked, they claim they have land registry records as well :/.

They claim things but the sources are not of good quality. The screenshots I've seen were the usual data: Name, address and phone number.

That might be because some interface(s) are supposed to show something like demo data when you enter an ID number. They want a membership for more. But this is speculation. I am sure we'll find out in a few days when it's already forgotten.

A few anectodal things from ekşisözlük claiming people were able to look up the medicines they are taking. Nothing conclusive and I didn't really have the chance to do a deep dive with my current bandwith. The files are supposed to be around 64GB.

Do you have a link to the files? I want to check this out.

Sorry no. I have to find it too. I can't do anything right now because I am on metered 4G.
