A ransomware attack has severely disrupted critical services across the Sault Ste. Marie Tribe of Chippewa Indians operations in Michigan's Upper Peninsula, forcing temporary closures of multiple facilities and departments.
The cyberattack, which began Sunday morning, has impacted computer and phone systems throughout the tribal administration, including five Kewadin Casinos locations, health centers, and various tribal businesses, according to Tribal Chairman Austin Lowes.
The attack has particularly affected the tribe's health division, leading to cancellations of scheduled medical appointments for primary care, radiology, and dental services. While emergency walk-ins are still being accepted, patients must bring lists of current medications and prescription bottles due to limited access to electronic systems.
All gaming operations at Kewadin Casinos have been halted indefinitely. While hotels remain open for current guests, new check-ins are unavailable. The tribal government continues to operate at limited capacity to serve its members.
The impact extends to various community services:
- Elder services remain fully operational
- Fishing and hunting licenses cannot be processed
- Local facilities are accepting cash payments only
- Gas stations are temporarily closed
- Tribal government meetings have been cancelled
The Sault Tribe, Michigan's largest federally-recognized tribe with over 44,000 members, relies heavily on casino revenue to fund community resources. Chairman Lowes indicated that while they hope to resolve the issue within a week, they are prepared for a longer disruption.
This incident adds to a growing list of ransomware attacks targeting Michigan governments, following recent cybersecurity breaches in Wayne County, Flint, and Traverse City. The tribe has enlisted third-party experts to help restore operations, though details about the investigation remain limited due to security concerns.
