Ex&Co (réseau Expert / Connexion)

ModerateReportedRetailSeptember 11, 2026

On 11 September 2026, an attacker claimed on a cybercrime forum to have leaked a file presented as coming from Boulanger.com, though sample analysis indicates it actually corresponds to after-sales service records from around fifty independent stores in the Ex&Co network (Expert and Connexion brands), in which Boulanger has held a stake since 2018. The file reportedly contains about 132,000 repair and warranty records covering roughly 61,000 distinct customers, opened between 2010 and September 2026, mainly in Meurthe-et-Moselle, Ardèche and Lot.

The precise link between contact details, the actual appliance purchased and the reported fault makes it easier to run fraudulent after-sales-service scams that appear legitimate.

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.
