Disclosure context

About Donutleaks

Donutleaks is a ransomware group that emerged in August 2022, operating with primarily financial motivations and demonstrating a pattern of targeting critical infrastructure and business sectors across multiple countries. The group's origin and specific affiliations remain largely undocumented in publicly available threat intelligence reports, with limited information available from major security firms or law enforcement agencies regarding their operational structure or potential ransomware-as-a-service model. Based on the limited public documentation available, the group has demonstrated a preference for attacking healthcare, technology, manufacturing, business services, and telecommunications sectors, with their attack methodology and specific technical capabilities not extensively detailed in current threat intelligence reporting. Donutleaks has been associated with approximately 42 documented victims primarily concentrated in the United States, Italy, Iran, and Spain, though specific high-profile campaigns or ransom demands have not been widely reported by major cybersecurity organizations or law enforcement agencies. The current operational status of Donutleaks remains unclear due to limited public threat intelligence coverage of this particular threat actor. The group has been linked to 42 public disclosures across our corpus. First observed on a leak site on August 24, 2022; most recent post July 24, 2024. The operation is currently inactive.

If your organisation is affected

A listing by Donutleaks means Gossler, Gobert & Wolters Group. appeared on a ransomware extortion site and data attributed to it has been published. 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, CERT-Bund (Germany), as required for your jurisdiction.
  • Monitor for the data appearing on Donutleaks'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.
