Tietoevry Corporation     PRESS RELEASE     29 January 2024   3:00 p.m. EET

The ransomware attack on one of Tietoevry’s data centers in Sweden took place during the night of January 19-20. Tietoevry immediately isolated the affected platform, and the attack has not affected other parts of the company’s infrastructure.

Tietoevry’s efforts are aimed at ensuring the impacted customer systems would be safely recovered as soon as technically possible. The systematic multi-phase work is advancing relentlessly in collaboration with the customers in question.

Today we can share that we have been able to make solid progress in the restoration of customer-specific systems over the past days. We continue to work around the clock with an extensive dedicated team of experts and technicians.

The customer-specific situations vary greatly, for example in terms of the solutions in question, customer-specific workloads and the volume and complexity of related data restoration. A restricted number of customer situations will require additional restoration actions that are being planned in close dialogue with those customers.

“We regret the inconvenience caused by this criminal malicious attack on our customers and all those affected by it. We will continue to work 24/7 on this and will continue our close collaboration with the police and other authorities, to accommodate them in every possible way to support the investigation”, says Venke Bordal, Head of Tietoevry Tech Services Sweden.

As ransomware attack is a serious criminal act, Tietoevry is in active dialogue with the relevant authorities, including the Swedish police. The police report was filed on the morning of Saturday January 20.
