Disclosure context

About tridentlocker

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. The group has been linked to 17 public disclosures across our corpus. First observed on a leak site on November 29, 2025; most recent post September 4, 2026. The operation is currently active.

If your organisation is affected

A listing by tridentlocker means SouthernCarlson appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Monitor for the data appearing on tridentlocker's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
