Disclosure context

About stormous

Stormous is a relatively new ransomware group that emerged in March 2022, operating primarily with financial motivations and has claimed responsibility for attacks against at least 165 victims across multiple countries and sectors. The group's country of origin remains unclear from publicly documented sources, though their operational patterns suggest they may operate as an independent entity rather than a established ransomware-as-a-service model. Limited public documentation from major security firms indicates the group employs common ransomware tactics, though specific details about their initial access vectors, encryption methods, and data exfiltration practices have not been extensively detailed in reports from CISA, FBI, or major threat intelligence providers. Their targeting appears geographically diverse with a focus on Spain, the United States, France, UAE, and Brazil, while showing particular interest in technology, hospitality and tourism, government, and business services sectors, though many of their victims span unspecified industries. As of current reporting, Stormous appears to remain an active threat, though the limited public documentation suggests they operate as a lower-tier ransomware group compared to more prominent families that receive extensive coverage from major security research organizations. The group has been linked to 220 public disclosures across our corpus. First observed on a leak site on March 22, 2022; most recent post May 13, 2026. The operation is currently active.
