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 …

Disclosure context

About beast

The Beast ransomware group is a relatively new threat actor that emerged in July 2025, operating with apparent financial motivations through their ransomware campaigns. With limited public documentation available from major security agencies, the group has demonstrated activity primarily targeting victims across the United States, United Kingdom, Brazil, South Korea, and Argentina, accumulating approximately 65 known victims since their emergence. Their targeting pattern shows a focus on healthcare organizations, manufacturing companies, educational institutions, and construction firms, suggesting an opportunistic approach rather than highly specialized sector expertise. The group's recent emergence means there is insufficient public intelligence from CISA, FBI, Mandiant, or other established security researchers regarding their specific attack methodologies, initial access vectors, or technical capabilities. Given the timeline of their first observation in mid-2025, Beast represents an active and emerging threat with their current operational status remaining unclear due to limited threat intelligence reporting from authoritative sources. The group has been linked to 106 public disclosures across our corpus. First observed on a leak site on July 29, 2025; most recent post August 25, 2026. The operation is currently active.

If your organisation is affected

A listing by beast means Winner appeared on a ransomware extortion site and is being pressured to pay before any publication. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
  • Monitor for the data appearing on beast's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
