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.

Attack summary

Severity: critical — The group claims exfiltration of regulated PII at scale (passports, medical records for all employees), combined with sensitive financial records, government project data, and physical security schematics — constituting a multi-category regulated data breach with significant downstream risk to both individuals and third-party clients including government entities.

Stormous claims to have exfiltrated 5 TB of data from TTT Corporation's internal infrastructure, demanding $900,000, and states that data has been published. The group claims possession of blueprints and CAD designs for high-profile clients, employee PII (IDs, passports, medical records), confidential contracts, tax reports, financial audits, and security schematics for client buildings.

What the group claims

$900k to Solve the Problem 5TB — While TTT Company was preoccupied with designing luxurious interiors and architectural masterpieces, they completely overlooked the design of a secure network. We have spent enough time within their internal infrastructure to conclude that their security is incredibly fragile. We have successfully exfiltrated all of the company's data and now possess 5 TB of the most sensitive information, including complete blueprints and CAD designs for prestigious clients (Toyota showrooms, gyms, luxury resorts, and government projects). We have accessed every employee's personal drive, including IDs, passports, and private medical records. Furthermore, we hold confidential contracts, tax reports (BCTC), internal financial audits, and detailed security schematics for client buildings.
