Disclosure context

About Dataleak

Dataleak is a relatively obscure ransomware group that emerged in December 2022 with apparent financial motivations, operating with a limited scope compared to major ransomware families. The group's origin and potential affiliations remain unclear based on publicly available threat intelligence, and there is insufficient documentation to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. Their attack methodology and specific technical capabilities have not been extensively documented by major cybersecurity firms or government agencies, though their targeting pattern suggests a focused approach on financial sector organizations. The group has primarily targeted victims in Germany with a concentration on financial services organizations, having compromised at least six known victims since their emergence. Given the limited public reporting and documentation from established threat intelligence sources such as CISA, FBI, or major security research firms, the current operational status of Dataleak remains uncertain, with their relatively small victim count and narrow geographic focus suggesting either limited capabilities or highly selective targeting criteria. The group has been linked to 6 public disclosures across our corpus. First observed on a leak site on December 2, 2022. The operation is currently inactive.
