Darkfield

Operator dossier

blacklock is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 64 public victims claimed by this operator between May 16, 2025 and July 2, 2025. Based on the limited publicly available information, Blacklock is an emerging ransomware group first observed in May 2025, operating with apparent financial motivations targeting organizations across multiple countries and sectors. The group's origin and potential affiliations remain unclear from documented sources, and there is insufficient public reporting to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. With 64 documented victims since their emergence, Blacklock has demonstrated a broad targeting approach across the United States, Canada, Spain, India, and the United Kingdom, with particular focus on technology, construction, manufacturing, and consumer services sectors, though their attack methodology, initial access vectors, and encryption tactics have not been extensively documented by major security research organizations. Due to the group's recent emergence and limited public reporting from established threat intelligence sources, notable campaigns and specific technical details of their operations remain largely undocumented in publicly available security research. As of current reporting, the group appears to remain active given their recent emergence date, though comprehensive analysis of their operational status requires additional documentation from established cybersecurity authorities.

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.
