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.

Where did you get that from? All I saw was: names, addresses and CPR numbers.

Additionally it was via third party access granted to private companies.

I think it is worth mentioning that age and sex is encoded in the social security number.

There are exceptions where the encoded birth date will be wrong (like immigrants with unknown birth dates) or dates where there are more people than the 4 digits that encode checksum validation and gender can handle.

They say that persons with protected address had not been leaked.

Nobody knows exactly what was accessed. What you have listed is what the register contains, not what was accessed. People with "Protected addresses" have specifically not been compromised.
