The April attack occurred in the town of Mount Desert on Mount Desert Island, Maine.
In Mount Desert Island, officials said the attack took computers offline for three days, but treatment plants were not affected because they are controlled manually.
Ed Montague, superintendent for Mount Desert Wastewater, said, “The office computers were down for approximately three working days… Our treatment plants were not affected as they are manually controlled with no automated inputs.” No ransom was paid and no personal information was compromised, Montague said, and town and IT professionals were notified.
