Datacarry is a newly emerged ransomware group first observed in May 2025, appearing to be financially motivated based on their targeting patterns across multiple industry sectors. The group's origin and operational structure remain largely undocumented by major threat intelligence organizations, with no confirmed country of origin or known affiliations to established ransomware families reported by CISA, FBI, or leading security researchers. Limited public documentation exists regarding their specific attack methodologies, encryption techniques, or whether they employ data exfiltration tactics prior to encryption. The group has claimed at least 16 victims across European nations including Belgium, Sweden, Spain, Italy, and Latvia, with their targeting spanning consumer services, financial services, healthcare, and transportation/logistics sectors. Given the recent emergence of this threat actor in May 2025, datacarry appears to remain active, though comprehensive threat intelligence profiles from established security organizations have not yet been published due to the group's nascent operational timeline. The group has been linked to 16 public disclosures across our corpus. First observed on a leak site on May 26, 2025; most recent post December 6, 2025. The operation is currently active.

If your organisation is affected
A listing by datacarry means Miljödata (1 day left) 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-SE (Sweden), as required for your jurisdiction.
- Monitor for the data appearing on datacarry'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.
