A data breach at a third-party service provider has impacted customers in Belgium, Germany, and the Netherlands. The affected retailer is Lidl, which operates around 12,900 stores across 32 countries in Europe and the US. The incident occurred when unauthorized parties briefly gained access to a separately stored file containing customer information of Lidl's online shop, resulting in exposure of first and last names, telephone numbers, email addresses, dates of birth, and customer numbers. This data does not include passwords or other sensitive payment information. Following swift action by its IT service provider, including notification of authorities and engagement with forensic experts, Lidl has urged customers to remain vigilant for potential phishing attacks or identity theft, particularly as the incident highlights the risks posed by third-party vendors.
