katholiekamersfoort.nl was compromised in a ransomware attack attributed to stormous in June 2026. The organization, operating in the Education sector in Netherlands, 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 church website's network (katholiekamersfoort.nl/) has been breached, resulting in the exfiltration of over 10 GB of data. This data pertains to donors, staff, and the personal information of a large number of individuals. The compromised data includes: Databases and Personally Identifiable Information (PII), internal network shares and document, contact lists, board and committee data, as well as system metadata.
