Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Beast on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Winner is located in south central South Dakota along the Oyate Trail at the crossroads of SD Highway 44 and US Highways 18 & 183. Agriculture is the backbone of our community. Tripp County is the largest cattle producer in South Dakota. Our farmers & ranchers also harvest a great deal of wheat and corn. Our open prairies and rolling hills provide an excellent habitat for a sportsman's paradise. Winner is known for top-notch pheasant hunting. Deer, turkey, prairie dogs, grouse, prairie chicken, dove, and coyotes are also hunted in the area. The Winner Youth Fishing Pond is a wonderful way to spend the afternoon fishing. Should you desire to fish on the Missouri River, it is a scenic 30 mile drive. A couple of unique landmarks to Winner are Leahy Bowl and the Winner Drive-In Theatre. If you happen to visit Winner in the summer, you will not be disappointed with the events at each of these attractions. The Winner Drive-In Theatre is one of very few Drive-Ins left in the USA. Leahy Bowl hosts many baseball games each summer and is well preserved by the community. We have many events year-round and Labor Day is our big celebration. Whether you are here for a week or the weekend or are considering relocating to a hometown with an emphasis on community and quality of life, we look forward to meeting you!
