BlackShadow is a relatively obscure ransomware group that emerged in December 2021 with a primary financial motivation, though their limited victim count suggests either a narrow operational scope or early-stage development. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, with no confirmed country of origin or clear operational model established by major security firms or government agencies. Their attack methodology and technical capabilities have not been extensively documented by reputable sources, though their focus on financial sector targets suggests some degree of sector-specific targeting preferences. With only three known victims documented since their emergence, BlackShadow has not conducted any widely publicized high-profile campaigns or attracted significant law enforcement attention compared to more prolific ransomware operations. The group's current operational status remains unclear due to limited public reporting and their relatively low profile within the broader ransomware ecosystem. The group has been linked to 3 public disclosures across our corpus. First observed on a leak site on December 18, 2021. 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.
