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.

If your organisation is affected

A listing by Dataleak means rkw-group.com Disclose the compressed package password 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 Dataleak's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
