Norwegian Police Investigate Major Data Breach at DNB Bank

Initial reports of a serious IT incident at Norway's largest bank, DNB, emerged late on March 21. A formal police investigation and a detailed bank statement are expected within the next 48 hours. Norwegian financial group DNB has confirmed it is dealing with what it calls a 'serious IT incident.' This incident is affecting some of the bank's customer-facing services. The National Authority for Investigation and Prosecution of Economic and Environmental Crime, known as Økokrim, has been officially notified about the situation. A DNB spokesperson provided a statement on the matter. According to the announcement, the spokesperson said, 'We are working intensively to secure our systems and understand the extent of this incident.' The bank's teams are focused on resolving the security problem and assessing its full impact on operations. The IT incident was first brought to light by DNB customers who found themselves unable to access the bank's online services. This disruption prompted the initial reports and led to the bank's internal investigation and subsequent engagement with Norwegian authorities like Økokrim. The bank's confirmation followed customer complaints about service access problems. DNB is Norway's largest financial services group, making this a significant event in the national banking sector. The police investigation by Økokrim, which handles economic and environmental crime, indicates the potential severity of the breach. The bank's statement about working to understand the extent suggests the full scope of customer data or system impact is not yet known. The expected formal statement from DNB within 48 hours will likely provide more details about the nature of the IT incident. The phrase 'serious IT incident' is the bank's own description of the event affecting its services. The involvement of a specialized police unit like Økokrim points to a possible criminal dimension to the data breach. The timeline shows events moved quickly from customer reports to a formal police investigation. The bank's priority remains securing its systems while authorities begin their investigative work.
