Raznatovic is an emerging ransomware group that first appeared in December 2023, operating with apparent financial motivations based on their targeting patterns and limited victim profile. The group's origin and affiliations remain unclear due to their recent emergence and relatively small operational footprint, with no publicly documented connections to established ransomware families or evidence of operating as a Ransomware-as-a-Service model. Their attack methodology and technical capabilities have not been extensively documented by major security firms, though their focused targeting of transportation and logistics sectors in Cyprus suggests a deliberate sectoral approach rather than opportunistic attacks. With only five documented victims since their emergence, Raznatovic has not conducted any widely publicized major campaigns or attracted significant law enforcement attention compared to more established ransomware operations. The group appears to remain active as of current reporting, though their limited scale of operations and narrow geographic focus suggest they are either a smaller independent operation or potentially a testing ground for techniques that may be expanded in future campaigns. The group has been linked to 5 public disclosures across our corpus. First observed on a leak site on December 17, 2023; most recent post January 7, 2024. The operation is currently inactive.

If your organisation is affected
A listing by raznatovic means Colonial Pipeline 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, CISA (United States), as required for your jurisdiction.
- Monitor for the data appearing on raznatovic'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.
