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.

About the victim

AI dossier — public-source company profile

Vouch (vouch.co.uk), operating alongside KYC UK, is a UK-based financial services company involved in identity verification and Know Your Customer (KYC) processes. The company collects and stores personal identity documentation and customer data as part of its compliance and verification services. No additional public site content was available to further characterise its scale or precise operations.

Industry: Financial Services & KYC Compliance

Attack summary

Severity: critical — The exfiltrated data includes government-issued identity documents (UK ID cards) and KYC records, constituting regulated PII at scale. This falls squarely within critical-severity criteria due to confirmed exfiltration of identity-verification data and biographic information, which carries high risk of identity fraud and regulatory breach under UK GDPR.

The Stormous ransomware group claims to have exfiltrated approximately 3GB of data from Vouch/KYC UK, including KYC records, UK ID card scans, email addresses, phone numbers, and full names. No encryption claim was made; the disclosure status indicates the data has been published.

What the group claims

Vouch does not protect its customers' data at all and stores it poorly. Many users' data, including KYC information, UK ID cards, email addresses, phone numbers, full names, and more, have been extracted. Approximately 3GB of data was collected.
