Just to note - the population of Denmark is 6,032,304.

So essentially the whole population's data has leaked. Furthermore, the notice says mv, which is abbreviation for etc. So it says "name, address, cvr number" etc.

That etc. is funny because the Danish government has a thing called NemID which you use to log into pretty much any online service, including banking, and you can install it on your phone, and when you lose it though you can verify by calling up and giving personal information to verify it is you.

Now there are a bunch of things about this system that are contemptibly stupid and annoying that I won't go into here because of my blood pressure. But now I wonder if the mv. of the personal data covers stuff you could conceivably be using to get a new NemID.

on edit: the really young have not had their data leaked, probably, and the excess of course covers people who used to live in Denmark and left.

I am going to be very curious to see if there are any downsides or negatives at all to this hacking happening. In theory this information could be used to scam a lot of Danes. In practice these major hacks end up fizzling out, in my experience - the data being less useful or more duplicated than people thought.

Just because we cannot identify any disadvantages does not mean that there are none.

Imagine a foreign state-sponsored agent waiting at the door of a public or private decision-maker, convincing them to cooperate. Home addresses are no joke. Especially if you can grep through the whole family tree.

It is more or less trivial to find someone's home address now if you try at all. Thats my point on duplicated data in hacks.

		It really depends and I often struggle with it. How do you do it? The German Melderegisters, for example, are now far more interested in the stated reason for your data request than they were ten years ago. Many things that are trivial in theory, given the right conditions, etc. are anything but trivial if you actually try to do it.

I think you mean MitID, but yes. I have tried going through the process of getting a new MitID at the citizen service desk, and the questions I am asked to verify that it is me are almost all family related. If the leaked data reveals things like parent/child and spouse relationships then that process is cooked.

		according to this article which I linked earlier because I thought the non-Danish readers might appreciate it, it "can include" family relationships https://cphpost.dk/2026-10-05/life-in-denmark/cpr-data-breac...

		ah yes, sorry, I worked on the NemID project and I often put NemID in place of MitID when I'm tired.
