According to a press release from Region Halland, it was the IT provider Inera AB who first reported on the logout error.

What it is about is that people who have logged out of the e-services, closed the browser and in some cases even restarted the computer, have been automatically logged in when they log on to 1177.se again.

"Is unacceptable"

Thus, other persons have had the opportunity to access the personal data. The error, which took place between January 5 and January 27, should now be rectified.

At Region Halland you are critical:

- This is unacceptable. We have a great responsibility to protect our residents' identities and personal data. And when it has to do with health, it is extra important. We take a very serious look at what has happened, ”says Måns Arnrup, IT director at Region Halland.

"Applies to the whole of Sweden"

How many people have been affected and the number of personal data that has been cleared is unclear - how many residents who shared a computer and logged in directly after each other are, according to Region Halland, "not possible to know".

However, Måns Arnrup confirms that all of Sweden is affected.

- This applies to all of Sweden, we take responsibility for Halland and our hallways. Inera AB is a joint supplier for the regions, he says.

Anders Nilsson is Security Manager at Region Halland:

- Security of our digital services is a high priority area in Region Halland. We take a very serious look at the incident and follow up what happened with the supplier Inera, he says in a press release.

The Stockholm region has contact with the supplier Inera.

- We do not know what the possible impact will be in our county right now, says Erik Berglund, Press Officer, Region Stockholm.

Almost exactly one year ago, the magazine Computer Sweden revealed another security leak at 1177 Care Guide. Then it was about 2.7 million recorded telephone calls from Care Guide 1177 were openly available on the Internet.
