Arkana is a relatively new ransomware group that emerged in March 2025, operating with primarily financial motivations based on their targeting patterns and victim selection. Given their recent emergence and limited public documentation, specific details about their country of origin and operational structure remain unclear, though their targeting of US and UK entities suggests sophisticated capabilities and potential ties to established cybercriminal ecosystems. With only six documented victims to date, Arkana appears to follow a selective targeting approach, focusing on high-value sectors including financial services, technology, energy, and consumer services, though their specific initial access vectors, encryption methods, and whether they employ double or triple extortion tactics have not been publicly documented by major threat intelligence organizations. No notable high-profile campaigns or significant law enforcement actions have been reported against this group, likely due to their recent emergence and relatively small victim count. Arkana remains active as of the available intelligence, though their limited operational footprint suggests they are either a newly formed group still developing their capabilities or a highly selective operation focusing on carefully chosen targets. The group has been linked to 6 public disclosures across our corpus. First observed on a leak site on March 25, 2025; most recent post June 6, 2025. The operation is currently inactive.

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.
