Dakota Boys and Girls Ranch Listed by Sinobi Ransomware Group

If you are a customer of Dakota Boys and Girls Ranch, here’s what is being claimed, and what it would mean for you.

Dakota Boys and Girls Ranch was listed on Sinobi's leak site. Sinobi claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Dakota Boys and Girls Ranch Listed by Sinobi Ransomware Group

On September 9, 2025, the Dakota Boys and Girls Ranch appeared on the leak site of the sinobi ransomware group. The nonprofit organization, founded in 1952 and headquartered in Minot, North Dakota, provides residential treatment and educational services for children and families. Internal files were allegedly exfiltrated during a ransomware attack, placing sensitive information belonging to current and former clients, employees, and their families at risk of public exposure.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that sinobi listed the Dakota Boys and Girls Ranch on its dark web leak portal. The organization is named in the listing as having experienced a ransomware incident in which attackers gained access to internal systems and removed files. No exact victim count has been released, and the precise volume or content of the stolen data remains unclear. Available reporting describes the exposed material as internal files, which in similar incidents often include documents containing names, addresses, dates of birth, treatment records, financial details, and employee information.

September 9, 2025 marks the date the group publicly listed the ranch. The sinobi leak site, accessible only via Tor, continues to display the organization’s data as proof of successful exfiltration. No evidence has surfaced that the attackers have yet published the full dataset, but ransomware groups routinely use such listings to pressure victims into payment.

Why This Matters for You and Your Family

When a children’s residential treatment center is breached, the families who sought help there are directly affected. Your child’s name, medical history, family contact information, or school records may now sit in an attacker’s archive. Even if you were never a client, employees’ families can also be exposed through payroll files, tax forms, or emergency contact lists. Once data leaves secure systems, it travels quickly through underground markets where identity thieves, stalkers, and fraudsters shop for fresh information.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
