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.

About the victim

AI dossier — public-source company profile

TTT Company is a firm operating in the interior design and architecture sector, undertaking projects for high-profile clients including Toyota showrooms, gyms, luxury resorts, and government facilities. The company produces blueprints, CAD designs, and architectural plans. No public website or registered address was available to confirm jurisdiction or scale.

Industry: Interior Design & Architecture

Attack summary

Severity: critical — The group claims exfiltration of regulated PII at scale (passports, IDs, private medical records for all employees), combined with sensitive government project data, financial audits, and security schematics. The volume (5 TB) and breadth of data types — including medical records and government-related materials — meets the critical threshold.

Stormous claims to have fully exfiltrated 5 TB of data from TTT Company's internal infrastructure, including CAD/blueprint files, employee personal documents (IDs, passports, medical records), confidential contracts, tax reports, financial audits, and security schematics for client buildings. A ransom of $900,000 has been demanded to prevent further disclosure.
