“It’s a serious attack,” said the company’s chief digital officer Ole-Marius Moe-Helgesen in a statement. “The entire worldwide digital infrastructure of Hurtigruten seems to have been hit.”
The company said it had alerted the relevant authorities when the attack was detected overnight Sunday to Monday. “The attack seems to be a so-called ransomware,” Hurtigruten added.
Ransomware is a kind of malware — malicious software — that encrypts the data of the target, locking the owner out of its own system until the victim agrees to pay for a decryption key to let him back in.
