Data breach — Moderate

On September 11, 2026, a hacker using the alias "fuie" posted a database of 132,230 records attributed to Boulanger.com on a cybercrime forum. File analysis shows these are after-sales service and warranty files opened between 2010 and September 2026 in about fifty stores of the Ex&Co partner network (Expert and Connexion brands), covering roughly 61,000 distinct customers. Each file links the customer's name, address, phone number and email to precise device details (brand, model, serial number) and to the purchase or repair case. Neither Boulanger nor Ex&Co had publicly confirmed the incident as of September 12, 2026.

These details could let a third party credibly impersonate after-sales support by referencing the customer's actual device, to push fake repair or warranty-extension offers.

## Exposed data

- Email address
- Full name
- Phone number
- Postal address
- Order history
- Other personal data

## What you can do

- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
