The large Norwegian energy services company Aker Solutions said a subsidiary company in Brazil has been subjected to a cyber attack that has impacted on its IT systems.

Aker Solutions said it does not yet know the full extent of the situation, and that a dialogue is being established with the authorities in Brazil about the incident.

In addition, its global IT organisation is working to resolve the situation with external expertise.

“The attack is currently directed at CSE, and the attackers claim that they have entered the IT systems, encrypted digital files and locked access to data,” said the company, led by chief executive Kjetel Digre.
