Darkfield

Operator dossier

tridentlocker is a ransomware operator currently active on public leak sites. Darkfield has indexed 16 public victims claimed by this operator between November 29, 2025 and April 27, 2026. TridentLocker is a recently emerged ransomware group that was first observed in November 2025, appearing to be financially motivated based on their targeting patterns across multiple high-value sectors. The group's origin and affiliations remain unclear given their recent emergence, with no publicly documented connections to other ransomware operations or confirmed country of origin, though their global targeting suggests they may operate independently rather than as part of an established RaaS model. Limited public documentation exists regarding their specific attack methodology, tools, or encryption methods, though their targeting of technology, public sector, energy, and telecommunication organizations suggests they likely employ sophisticated initial access techniques and may utilize double extortion tactics given the sensitive nature of data in these sectors. With only 15 documented victims across the United States, Canada, Japan, Iraq, and Great Britain, the group has not yet conducted any widely publicized major campaigns or attracted significant law enforcement attention. TridentLocker appears to remain active as of their recent emergence, though comprehensive threat intelligence remains limited due to their brief operational history.

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.
