RavnAir Group was forced to ground flights on Saturday following a cyber-attack on the Alaskan company’s computer network.
In a statement released on Saturday morning, RavnAir wrote: On Friday, December 20th, RavnAir Group experienced a malicious cyber-attack on our company’s IT network.
The nature of the attack was not disclosed, however, the company did reveal that threat actors specifically targeted the small airline’s turboprop-powered regional airliner the De Havilland Canada DHC-8 aircraft, commonly known as the Dash 8.
As a result of the incident, the airline had to disconnect its entire Dash 8 maintenance system and the back-up system.
All RavnAir Alaska Dash 8 flights that were scheduled to take place on Saturday, December 21, a crucial day of travel in the busy holiday season, were affected.
PenAir flights and RavnAir Connect flights were unaffected by the incident, as they were able to run on back-up systems.
RavnAir wrote: While we continue to work with the FBI, other authorities, and a cybersecurity company to restore affected systems, we are proactively cancelling all RavnAir Alaska Dash 8 flights until 12 noon today, and we expect to experience other schedule cancellations and delays within the RavnAir Alaska (Dash 8 Aircraft) network throughout the rest of the day because the cyber-attack forced us to disconnect our Dash 8 maintenance system and its back-up.
RavnAir spokesperson Debbie Reinwand said that 260 passengers were affected by the malicious cyber-attack. Six flights were cancelled, including the 1:30 p.m. flight from Unalaska to Anchorage.
RavnAir Group serves 100 different communities in Alaska from its headquarters in Anchorage. Many of the communities who fly with RavnAir are inaccessible by road.
