More than 20,000 Danske Bank customers affected by leak discovered in October 2025

The addresses are said to have become visible in connection with payments, and the exposure may have posed risks to customers' personal security. The leak went on for several months before it was discovered in October 2025. However, the bank's affected customers have only now been informed, writes Finans.dk and others.

No customers in Sweden will be affected, the bank says.
