Dunghill_Leak is a relatively obscure ransomware operation that emerged in April 2023, primarily motivated by financial gain through extortion activities targeting small to medium-sized organizations. The group's country of origin and potential affiliations with other cybercriminal organizations remain unknown due to limited public reporting from major threat intelligence firms and law enforcement agencies. Based on their targeting patterns, the group appears to focus on opportunistic attacks against businesses in English-speaking countries, particularly the United Kingdom, Canada, and United States, as well as expanding operations into South American markets including Brazil and Bolivia, with a preference for victims in business services and technology sectors. With only 16 documented victims since their emergence, Dunghill_Leak operates as a smaller-scale ransomware group compared to major threat actors, and specific details about their attack methodologies, initial access vectors, encryption techniques, or whether they employ double extortion tactics have not been extensively documented in publicly available threat intelligence reports. The group's current operational status remains unclear, as limited public information prevents a comprehensive assessment of their ongoing activities or potential law enforcement disruption efforts. The group has been linked to 16 public disclosures across our corpus. First observed on a leak site on April 10, 2023; most recent post July 1, 2025. The operation is currently inactive.

If your organisation is affected
A listing by Dunghill_Leak means The Printing House 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, CCCS (Canada), as required for your jurisdiction.
- Monitor for the data appearing on Dunghill_Leak'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.
