Intersport

Intersport operates as an international sporting goods retailer, offering a broad range of sports equipment, apparel, footwear and accessories for both amateur and professional athletes. The company maintains a network of physical stores alongside online platforms that serve customers in multiple European countries, including France and several Balkan nations such as Slovenia, Croatia, Serbia, Bosnia and Herzegovina and Montenegro. Its product assortment covers team sports, fitness, outdoor activities and seasonal merchandise, positioning it as a one‑stop shop for sporting needs. Intersport’s online channels support e‑commerce transactions, loyalty programs and gift card services, which are integrated with its point‑of‑sale systems in brick‑and‑mortar locations. The retailer’s headquarters are located in Switzerland, reflecting its central European base of operations.

A significant data breach disclosed in March 2025 revealed that personal information of approximately 3.4 million French customers was exposed, including names, email and postal addresses, invoice numbers, PayPal references, transaction amounts, types of bank cards used and loyalty card numbers. Prior to that, a ransomware attack by the Hive group in November 2022 disrupted point‑of‑sale functionality, loyalty programs and gift card services in French stores, forcing a shift to manual checkouts during a peak sales period. In late 2020 the firm experienced two distinct incidents: first, Magecart skimming code was injected into its online checkout pages across several Balkan markets, and shortly thereafter Conti ransomware actors claimed to have exfiltrated internal files, although the company did not publicly acknowledge the ransomware episode. Earlier in April 2020 a web skimming attack affected its European e‑commerce sites during the pandemic‑driven increase in online shopping, with malicious payment‑card‑stealing scripts intermittently active on regional website versions. These incidents collectively illustrate Intersport’s extensive digital footprint across European markets and the recurring cyber‑threat landscape faced by large sporting goods retailers. The company’s scale is evidenced by the breadth of its customer base, the geographic spread of its stores and online services, and the volume of data involved in the disclosed breaches.
