Groove is a relatively minor ransomware operation that emerged in September 2021, primarily motivated by financial gain through extortion activities. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, with limited information available about their operational structure or potential ties to other cybercriminal organizations. Based on available data, Groove has demonstrated a focused targeting approach, with documented attacks against media sector organizations, though their specific attack methodologies, initial access vectors, and technical capabilities have not been extensively analyzed or reported by major security firms. The group's operational scale appears limited, with only 13 known victims documented in public reporting, suggesting either a smaller operation or one that has maintained a relatively low profile compared to major ransomware families. Groove's current operational status remains unclear due to the limited public documentation and intelligence reporting available about this particular threat actor. The group has been linked to 13 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post October 30, 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.
