Orca is an emerging ransomware group that was first observed in September 2024, appearing to be financially motivated based on their targeting patterns and operational behavior. The group's origin and affiliations remain unclear due to their recent emergence, with insufficient public documentation from major security researchers to definitively establish their country of origin or whether they operate as a Ransomware-as-a-Service model. Limited public information is available regarding their specific attack methodologies, initial access vectors, or encryption techniques, as major cybersecurity firms and government agencies have not yet published detailed technical analyses of their operations. The group has reportedly compromised at least four known victims across a geographically diverse range including Colombia, China, Austria, and Tennessee, with their attacks primarily targeting organizations in the technology, manufacturing, and transportation/logistics sectors. Given the group's recent emergence in September 2024 and lack of extensive public reporting, Orca appears to be in the early stages of their operations and remains active, though comprehensive threat intelligence on their capabilities and impact is still developing within the cybersecurity community. The group has been linked to 5 public disclosures across our corpus. First observed on a leak site on September 16, 2024; most recent post April 27, 2026. 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.
