Disclosure context

About Cloak

Cloak is a relatively new ransomware group that emerged in August 2023, operating with primarily financial motivations and demonstrating a broad international targeting scope with 162 documented victims across multiple sectors. The group's origin and specific affiliations remain undocumented in public threat intelligence reporting, though their operational patterns suggest they may operate independently rather than as part of a larger ransomware-as-a-service ecosystem. Limited public documentation exists regarding their specific attack methodologies, encryption techniques, or data exfiltration practices, though their targeting patterns indicate sophisticated capabilities to compromise organizations across diverse sectors including business services, technology, healthcare, and manufacturing. The group has demonstrated a preference for targeting victims in English-speaking countries and Western Europe, with the United States, Germany, United Kingdom, Canada, and Italy representing their primary geographic focus areas. Cloak appears to remain active as of current reporting, though the relative scarcity of detailed public analysis from major threat intelligence firms suggests either operational security effectiveness or a lower profile compared to more established ransomware operations. The group has been linked to 166 public disclosures across our corpus. First observed on a leak site on August 24, 2023; most recent post June 18, 2026. The operation is currently active.

If your organisation is affected

A listing by Cloak means farwickgrote.de 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, CERT-Bund (Germany), as required for your jurisdiction.
  • Monitor for the data appearing on Cloak'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.
