Disclosure context

About Dunghill_Leak

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.

Attack summary

Severity: critical — Sabre operates critical travel infrastructure processing reservations for hundreds of airlines and thousands of hotels globally, meaning exfiltrated data almost certainly includes large-scale PII (traveler personal and payment data), regulated financial data, and sensitive operational data for critical travel infrastructure. The disclosed status is 'data_published', confirming exfiltration has been executed and data is now publicly exposed.

Dunghill Leak claims to have exfiltrated data from Sabre Corporation and has published the data, suggesting confirmed exfiltration of sensitive business and potentially personal data held within Sabre's travel technology systems. The post does not specify encryption, indicating this may be an exfiltration-only incident with data now disclosed.
