Darkfield

Operator dossier

Blackout is a ransomware operator currently active on public leak sites. Darkfield has indexed 12 public victims claimed by this operator between February 26, 2024 and July 19, 2026. Blackout is a recently emerged ransomware group that began operations in February 2024, with their primary motivation appearing to be financial gain through extortion activities. The group has demonstrated relatively limited scope with nine documented victims to date, but has shown geographic diversity in their targeting across Greece, France, Germany, Canada, and Croatia. Their sector preferences indicate a focus on business services, healthcare, manufacturing, and transportation/logistics industries, suggesting they may target organizations with critical operational dependencies that increase pressure for ransom payment. Due to the group's recent emergence and limited public documentation from major security firms and government agencies, details regarding their specific attack methodologies, initial access vectors, encryption techniques, and operational structure remain largely undocumented in open-source intelligence reporting. No major high-profile campaigns or significant law enforcement actions have been publicly reported in connection with this group's activities. Given the February 2024 first observation date and the relatively small victim count, Blackout appears to be a newly active but minor player in the ransomware landscape, though their current operational status and potential growth trajectory remain subjects for continued monitoring by threat intelligence analysts.

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 changes from active to dormant when no new disclosure appears for 60 days. Without a disclosure date, activity is unknown. 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.
