I am so done, my cpr is leaked oh no. Like I don't

CPR is the national register of all people (Central Person Register).

CPR is the administrator. There is more information in the linked press release from the ministry:

This is a huge headline story in Denmark today and I choose to link danish content as they are the primary source.

The only current english language sources are paywalled:

https://www.bloomberg.com/news/articles/2026-10-05/denmark-d...

Non-paywalled but major danish news outlet (National Brodcaster):

For those not getting the scope of this. The following has been compromised for all living danish citizens and foreign nationals which have had recidence. And quite a few dead ones as well.

- Social security number

- Age

- Sex

- Family relations

- Physical address

- Protected addresses

- Sex change

This is a country with quite good health records. Unfortunately also previous problems with proper non-reversible anonymisation of said data when used for research.

The article mentions that they accessed the information through a Danish company whose access has been revoked now. I find it really surprising that a company could access these records without any limitations on which info or how many records they can pull.

Just that easily all the private conversations of everybody in the EU can leak if Denmark succeeds at outlawing E2E encryption with its Chat Control proposal.

Not trying to downplay the situation, but I hope this will be eye opening to the responsible people.

I'm seriously at a point where I'm opposed to talking to my doctor because the information may be digitally recorded and leaked, going on a flight because my passport may be used to aqquire a loan by cybercriminals, comparing car insurance because my phone will be called by robocallers selling me things or verifying my ID with websites because it might be used to associate my information with whatever else I do online.

I don't think, for a vast majority of cases, these companies I'm forced to interact with can be trusted with my data and it's having a real world negative impact. Even with the best intentions the information is somehow valuable to steal and I'm baffled how it's not secure.

There should be some consequences for companies asking for things like SSN/National Insurance numbers on job adverts or retaining drivers licence photos after test driving a car, they just don't need the data anymore.

In the past few months, there were several huge data leaks also:

- in Poland (from private medical companies used by doctors) with estimated 20M affected people (half of population)

- in France (from tax office), 678k people affected

With AI getting more capable, and with Russia escalating things, I unfortunately expect more to come.

Let me guess, the Danish government will find a way to prove that GDPR doesn't apply to them.

But this is incredibly bad.

As someone who spend a decade in the Danish public sector, among other things working in groups on national architecture. I'd say that we reap what we sow. IT and digitalisation is not taken very serious in our public sector. In most places it's placed under something, and until recently it didn't have it's own ministry. Right now it's even a shared ministry, and there is little focus on cyber security. What has arrived in recent years is solely based on the thread of hybrid attacks from Russia.

Compare this to the ministry of transportation, which has full resources. This is despite the fact that most people in this country spend less time commuting than they do working on a computer. Not that transportation isn't important, but maybe digitalisation is as well?

My personal CPR has been leaked a couple of times though. Hilariously the first time it was leaked when a couple of unencrypted laptops were stolen from the biggest IT union in the country. We have a system in place where you can flag your CPR as having been leaked. Though I suppose now we might as well consider every one of them to be leaked. In theory a CPR on it's own was never meant to give any sort of authority or access, but again, this wasn't the practice in a lot of place. So I guess this leak may be a blessing in disguise in that sense as well, as it'll highten security because of broken trust.

As someone who works with CPR data in Denmark, this does not surprise me at all. Private companies access the data through an API, and anyone who works at such a company can look up CPR data as they please.

If people don't go to jail, there will be no change.

Altman at it again?

it feels this will keep happening specifically to Europe for three reasons: a) most countries took an anti-AI approach b) they reject frontier models in favor or "Sovereign" solutions c) they're replacing software with weaker/more vulnerable options

public servant engineers are token poor and will be out of the latest defense tools

In Sweden, to avoid this kind of malicious leaks, we leak the residents' data officially. https://hitta.se lets you look up personal numbers, names, addresses, birthdays and sometimes phone numbers of any resident. The residents are not asked for consent, the data goes there automatically (some of my friends had success with having it removed from hitta, but it comes back once you change residence address).

It's quite convenient, when you meet a new friend, to go and check what neighbourhood they're from, who do they live with and where they lived before.

What's the big deal, Danes? What do you have to hide?

(The provocative tone is intentional as a joke, I'm not even a Swede, I just find the brotherly rivalry between Scandinavians amusing.)
