Summary of the Decision

Origin of the case  

The Finnish SA launched an investigation based on a complaint filed by a customer. A technical investigation revealed serious data security issues with the controller’s loan comparison services. When the seriousness of the data security issues became apparent in spring 2024, the company was ordered to immediately cease processing of the personal data relating to loan applicants in its electronic services.

 

Key Findings

Sambla Group’s loan comparison services lacked adequate restrictions to prevent third parties from accessing the data in the loan applications (art. 32 GDPR, art. 25 GDPR and art. 5(1)(f)). Due to poor data security, the content of customers’ loan applications was accessible to third parties through personal URLs intended for the customers. Anyone with access to the URL and sufficient technical expertise to exploit the security vulnerability had direct access to the data. The technical investigation revealed that the URLs had been targeted with phishing and personal data had been disclosed to third parties. The information available through the links included at least the loan applicant’s contact details, as well as information on their income, housing costs, marital status and possible children. 

 

Decision 

The Finnish SA imposed an administrative fine of EUR 950 000 on the controller. The controller was also ordered to notify its customers of the incident. The controller has announced that it has stopped using the vulnerable URLs and improved the data security of its services.
