ams-group.co.uk FULL DATA DUMP 33GB

ams-group.co.uk FULL DATA DUMP 33GB was compromised in a ransomware attack attributed to stormous in May 2026. The organization, operating in the Business Services sector in United Kingdom, was added to the group's data leak site as part of an extortion campaign.

stormous operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.

The extracted data comprises administrative and financial records, payroll sheets, and client and partner directories, alongside technical and engineering specifications, employee records, and business plans. It also includes architectural designs, official contracts, detailed engineering reports, and construction site maps, as well as risk assessments, internal correspondence, and tax and legal information.
