Denmark's Styrelsen for Samfundssikkerhed has published guidance for citizens who need extra protection following the hacking of the CPR register last month, when 8.8 million Danish CPR numbers and other personal data, including names and addresses, were leaked, according to DR.

The guidance is aimed at particularly vulnerable or exposed people, including public figures and people who have previously been subjected to harassment. The agency also names people whose work "could be interesting to criminals", people "whose name could be misused", and people who "have a name that could put one at risk of harassment or be associated with vulnerable social, ethnic or religious minorities".

The agency asks those affected to consider whether name and address protection or a hidden phone number could be relevant. A second part of the advice concerns social media, for example setting up a private profile for a narrow circle and avoiding sharing personal details.

The guidance is described by Berlingske as being for citizens "in need of extra security in the event of a leak of personal data". Styrelsen for Samfundssikkerhed has published the full guidance on its own pages.
