Disclosure context

About AiLock

AiLock is an emerging ransomware group first observed in March 2026 with a primarily financial motivation, having targeted at least 24 known victims across multiple sectors. The group's origin and affiliations remain largely undocumented by major threat intelligence organizations, though their targeting patterns suggest a broad operational scope spanning the United States, Canada, Great Britain, China, and Germany. Based on publicly available information from security researchers, AiLock appears to focus on technology companies, consumer services, manufacturing, and public sector entities, though specific attack methodologies, initial access vectors, and encryption techniques have not been extensively documented by CISA, FBI, or major security firms. The group's relatively recent emergence and limited public documentation suggest they may be a smaller operation or newly formed entity, with no notable major campaigns or high-profile ransoms publicly reported by established threat intelligence sources. Given the March 2026 first observation date and lack of subsequent major public reporting, AiLock's current operational status and capabilities remain largely undetermined by mainstream cybersecurity organizations. The group has been linked to 34 public disclosures across our corpus. First observed on a leak site on March 3, 2026; most recent post May 18, 2026. The operation is currently active.
