Boyne City cyber incident disrupts utility billing and payments

Boyne City detected a cybersecurity incident on May 11, 2026 that affected municipal computer, email and utility-billing systems. Residents temporarily could not make utility payments online or in person, and account balances and payment histories were unavailable. Billing cycles were delayed and the city was still processing the resulting backlog during restoration. The Gentlemen later claimed the incident, but public evidence did not establish the technical attack mechanism.
