Chelan County faces third week outage after Memorial Day malware

On June 8, Andrew Simpson reported that Chelan County is facing its third week of disruptions due to a malware incident detected over Memorial Day weekend. Officials became aware of the issue on May 24 and promptly shut down affected systems while collaborating with specialists to assess the situation and restore operations. The incident was reported to federal law enforcement, and the investigation is ongoing.

As a result, email, phone, and computer systems remain offline for various departments, and several county-operated websites are not accessible. No criminal group has claimed responsibility for the attack.
