Nordnet, a financial services company, is facing scrutiny following unauthorized trading activities on its platform. Reports indicate that a Swedish customer sold shares worth €7,000 from a Finnish client's account. This incident is part of a broader issue where customers were reportedly logged into incorrect accounts, prompting Nordnet to disable its app temporarily. The Swedish Financial Supervisory Authority (Finansinspektionen) has described the situation as serious, and potential fines for Nordnet cannot be ruled out. Additionally, it has been reported that approximately 200 of the 1,500 affected accounts were Swedish, highlighting the extent of the breach.
