The National Bureau of Investigation (NBI) is investigating a Denial of Service (DoS) attack on the OP Pohjola financial services group. The attack shut down online banking and direct debit services, but the bank has no leads on who might have launched it.
Police are investigating an attack on Finnish bank OP Pohjola’s online banking services that caused disruption for customers using online banking and card payments on New Year’s Eve. The company said in a press release that traffic in the denial of service attack originated both inside and outside Finland.
The firm is investigating the incident in collaboration with the authorities, network operators and IT services provider, Tieto. A formal police complaint has been filed and OP says that the National Bureau of Investigation is looking into the case.
The disruption started on Wednesday at around 16:30, according to the bank, and was only fixed after midnight. Disruption could continue, and those located outside Finland could face difficulties in using OP’s services.
