AIDA is cancelling its New Year’s Eve cruises for the AIDAperla and AIDAmar, citing IT problems as German media widely reported the company was facing a cyber security issue.

The AIDAperla is now set to resume service in the Canaries on January 2, followed by the AIDAmar on January 3.

Bild, a German newspaper, reported on Monday a cyber security issue at both the AIDA headquarters in Rostock and aboard the company’s vessels. Citing passengers aboard, Bild said that the ships’ onboard boarding card system was not functioning. 

“The boarding pass system has stopped working,” one passenger said. “Slips of paper are used that would otherwise be automatically debited, for example when you buy something. We learned secretly from the staff that there had been a hacker attack on the AIDA servers.”
