INCIDENT: Cyberattack Shut Down Oahu Transit Services

Oahu Transit Services suffered a cyberattack causing a “mass disabling of online servers” for TheBus and TheHandi-Van systems. City officials said they are working with the FBI, the Secret Service, and Honolulu police as those agencies investigate.

The cyberattack on Oahu’s bus system “has the trappings” of being a ransomware attack, according to Roger Morton, director of the Department of Transportation Services, although it is still being investigated. Morton said that to his knowledge, no personal information from TheBus or TheHandi-Van riders using the HOLO card has been compromised. “The HOLO card information that we do have is contained in a city server, not an OTS (Oahu Transit Services) server, and there’s no evidence that there has been any intrusion into the city system,” he said.

Unable to access, view, or print the day’s customer reservations, OTS fell back to schedule reservations manually urging customers to call for same day reservations starting from 5:00am.
