Disclosure context

About dunghill

The dunghill ransomware group is a relatively new financially-motivated cybercriminal operation that emerged in April 2023, with documented attacks against 16 victims across multiple countries and sectors. Based on limited public reporting, the group's origin and affiliations remain unclear, though their targeting patterns suggest they operate as an independent entity rather than a established ransomware-as-a-service operation. The group has demonstrated a preference for targeting business services and technology sectors, with attacks documented across the United Kingdom, United States, Brazil, Bolivia, and Taiwan, indicating either a broad opportunistic approach or the use of initial access brokers to expand their geographic reach. While specific technical details about their attack methodology, encryption techniques, and extortion tactics have not been extensively documented in public threat intelligence reports, their multi-country victim distribution suggests they employ common initial access vectors such as phishing, credential theft, or exploitation of internet-facing vulnerabilities. No major high-profile attacks or significant law enforcement actions against the dunghill group have been publicly reported, likely due to their recent emergence and relatively small victim count compared to more established ransomware operations. As of current reporting, the group appears to remain active with limited public visibility into their operations. 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: high — Data has been confirmed as published by the threat actor against a major public transport operator serving millions of passengers across multiple countries, with likely exposure of employee PII, financial data, and government contract information. The scale of the organisation (27,000 employees, multi-national operations) and public-interest nature of the sector elevates severity, though absence of confirmed regulated medical or defence data prevents a critical rating.

The Dunghill ransomware group claims to have conducted an attack on Go-Ahead Group resulting in data publication ('data_published' status), indicating exfiltration of company data. No ransom amount or specific data volume was stated, but the disclosure implies sensitive corporate and operational data has been leaked.
