According to DN's analysis, the leak includes names and addresses, and in some cases also personal identification numbers and refund claims. The leak includes people with protected personal data.
DN reports that the leak, which a hacking group is said to be behind, likely occurred at the end of last year, but that much of the information is several years old.
ATG's cybersecurity manager Erik Täfvander says in a written response that he was not aware of the hacker group's "latest publication" and continues:
"We are aware that ATG has previously been listed on sites that collect various darknet leaks from various threat actors, but we have not received any evidence that an attack has been successful."
