The police driving licence register, including the personal identity (CPR) number register were hacked in the summer of 2012 and may have been changed, with hackers also having retrieved information about CPR numbers and people posted as wanted in the Schengen area, according to the Danish national police.
The police say that data hackers may also have had access to registers from the Tax Authority and the Modernisation Agency, in a previously undiscovered attack that seems to have gone on from April to August 2012.
The Security and Intelligence Agency and specialists from the Defence Intelligence Cyber Security Unit are currently investigating the break-in. A Swedish national currently in prison in Sweden is suspected of being involved, with Denmark applying for his extradition. A Danish man is also believed to have been involved in the attack.
