Darkfield

Operator dossier

Spook is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 35 public victims claimed by this operator between October 4, 2021 and October 19, 2021. Spook is a relatively obscure ransomware group that emerged in October 2021, operating with primarily financial motivations and targeting organizations across multiple sectors. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, with limited information available from major security firms regarding their operational structure or potential ties to other cybercriminal organizations. Based on observed targeting patterns, Spook has compromised approximately 35 victims across multiple countries, with a notable focus on the United Kingdom, United States, Italy, and Hungary, while primarily targeting media companies, manufacturing firms, construction organizations, and government entities. Due to the group's relatively low profile and limited public documentation from established threat intelligence sources, specific details regarding their attack methodologies, initial access vectors, encryption techniques, or extortion tactics have not been widely reported by CISA, FBI, Mandiant, or other reputable security researchers. The group has not been associated with any widely publicized high-profile attacks or notable ransomware campaigns that have gained significant attention in cybersecurity circles. Given the limited public reporting and threat intelligence coverage, the current operational status of Spook remains unclear, with insufficient documented evidence to determine whether they continue active operations, have rebranded, or ceased activities.

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.
