Darkfield

Operator dossier

Groove is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 13 public victims claimed by this operator between September 9, 2021 and October 30, 2021. 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.

How we know this. Operator profiles on Darkfield are built from continuous monitoring of every leak site the group is known to operate, cross-correlated with community-curated feeds (RansomLook, ransomware.live, RansomWatch, MISP-galaxy). Status flips from active to inactive when no new disclosure appears for 60 days. MITRE ATT&CK mappings shown in the interactive section below are sourced from CISA, vendor analysis, and the MITRE community catalog — we attribute each technique back to its source. Aliases reflect operator re-brands and affiliate splits.
