Kronos Private Cloud services, a program used by the Honolulu Board of Water Supply and the city’s emergency medical services, was cyberattacked with ransomware over the weekend.

BWS was notified of the problem on Sunday evening. BWS uses the service for its timesheet system. BWS immediately shut off access to the program, an agency press release said.

Honolulu spokesman Tim Sakahara told that the city’s EMS department was also impacted. He told the station that employees are logging their hours manually but that no employee or patient information has been compromised.
