Disclosure context

About Dragonforce

Dragonforce is a relatively new ransomware group that emerged in December 2023, operating with apparent financial motivations based on their targeting patterns and victim selection. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their rapid accumulation of 439 documented victims suggests either sophisticated capabilities or possible connections to existing ransomware infrastructure. Based on their targeting patterns across diverse sectors including manufacturing, business services, technology, and construction, Dragonforce appears to employ opportunistic attack methodologies, though specific initial access vectors, encryption methods, and extortion tactics have not been publicly detailed by major security firms or law enforcement agencies. The group has demonstrated a preference for targeting organizations primarily in English-speaking countries and Western Europe, with the United States, United Kingdom, Germany, Australia, and Italy representing their most frequent victim locations, suggesting possible language capabilities or geographic operational preferences. As of current reporting, Dragonforce appears to remain active given their recent emergence and ongoing victim acquisition, though the lack of detailed public analysis from major threat intelligence organizations indicates either operational security measures that have limited researcher visibility or that the group has not yet conducted sufficiently high-profile attacks to warrant extensive public documentation by CISA, FBI, or established security research firms. The group has been linked to 627 public disclosures across our corpus. First observed on a leak site on December 13, 2023; most recent post July 14, 2026. The operation is currently active.

If your organisation is affected

A listing by Dragonforce means CMC Expertise Comptable appeared on a ransomware extortion site and is being pressured to pay before any publication. 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 Dragonforce'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.
