The OP Financial Group reported a cyberattack on its Osuuspankki website on Sunday. OP, which claims to be Finland’s largest financial group, reported on Sunday morning an indefinite interruption of its services.

At the moment, Lotta Ala-Kulju, communications director at Osuuspankki, told tabloid newspaper Iltalehti that the cause of the technical disruption was being clarified.

“This morning, we discovered that the op.fi service login page had been the target of a cyberattack which caused an interruption. As a result, we put the entire service into a serviceable state and investigated the question.” Teemu Ylhäisi, head of information security for OP Financial Group, told Finnish news agency STT.

In the afternoon, OP said on Twitter that the attack had been avoided and online services were being restored. He added that other mobile services and payment cards were working normally.

At around 1:30 p.m., the company said a cyber attack affected connections to its site but the online service was functioning normally again. He did not provide more information about the attack.

“Our customers’ information and money have not been compromised, and all OP services are now operating normally. We apologize for the inconvenience,” he said in a tweet.

According to STT, the disruption lasted from 6 a.m. until around 12:30 p.m.

OP on Friday warned against sending phishing messages to Finnish cellphones, claiming to be from the bank and asking recipients to click on a link, supposedly to confirm a payment.
