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 162 public disclosures across our corpus. First observed on a leak site on August 24, 2023; most recent post February 24, 2026. The operation is currently active.
