Disclosure context

About shinyhunters

Based on the limited publicly available information, shinyhunters appears to be a recently emerged ransomware group first observed in October 2025, primarily motivated by financial gain through extortion activities targeting organizations across multiple sectors. The group's origin and potential affiliations remain unclear due to their recent emergence, and there is insufficient public documentation to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. Their attack methodology and specific technical capabilities have not been extensively documented by major threat intelligence firms, though their targeting pattern suggests a broad opportunistic approach rather than sector-specific specialization. The group has reportedly victimized approximately 77 organizations, with primary targeting focused on the United States, France, Japan, Germany, and Australia, showing particular interest in consumer services, technology, financial services, transportation and logistics, and education sectors. Given the group's very recent emergence in late 2025, there are no widely reported major campaigns or high-profile incidents documented by established security research organizations, and no known law enforcement actions have been publicly reported against this group. The current operational status of shinyhunters remains active based on available reporting, though comprehensive threat intelligence profiles from major security firms like Mandiant, CrowdStrike, or government agencies have not yet been published due to the group's recent appearance in the threat landscape. The group has been linked to 108 public disclosures across our corpus. First observed on a leak site on October 3, 2025; most recent post May 12, 2026. The operation is currently active.
