KINGMAN – Kingman Mayor Jen Miles said the city has recovered about 95% of the functionality of its municipal computer network following a crippling cyber-attack discovered Feb. 26. She said Information Technology department staff believe the hack attack occurred by aggressive malware, affording access through destructive email inadvertently opened by a city employee.

“They do believe that someone clicked on an errant email,” Miles said. “It was like they got in, in a real sophisticated way.”

Miles said the timetable for total recovery of the system remains unclear.
