Disclosure context

About Dark Project

Dark Project is a ransomware group first observed in August 2026 with an apparent primary motivation of financial gain, based on its targeting profile and operational patterns consistent with other profit-driven ransomware actors. As of the time of this writing, no major cybersecurity organizations including CISA, the FBI, Mandiant, or other reputable threat intelligence firms have published detailed public reporting attributing Dark Project to a specific nation-state, threat actor cluster, or affiliated ransomware ecosystem, and it remains unclear whether the group operates as a Ransomware-as-a-Service platform or as an independent closed operation. Based on available victim telemetry, the group has claimed at least 18 known victims across a geographically diverse range of countries, with the United States, United Kingdom, Mexico, the Philippines, and Germany representing its most frequently targeted regions. Its sectoral focus spans manufacturing, healthcare, transportation, hospitality, and education, suggesting an opportunistic targeting methodology rather than a narrowly defined strategic focus, though the inclusion of healthcare and critical infrastructure-adjacent sectors such as transportation warrants continued monitoring. Due to the group's recent emergence and limited public documentation at this time, specific details regarding initial access vectors, encryption implementation, extortion tactics, and tooling remain unconfirmed by open-source intelligence sources, and analysts should treat any further claims with appropriate caution pending corroborating reporting from authoritative sources. Dark Project should be considered an emerging threat actor under active observation. The group has been linked to 37 public disclosures across our corpus. First observed on a leak site on August 5, 2026; most recent post September 9, 2026. The operation is currently active.

If your organisation is affected

A listing by Dark Project means Master Manufacturing Co., Inc. 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.
  • Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
  • Monitor for the data appearing on Dark Project'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.
