According to fuitededonnées.fr, Eurofiber France told some partners of a security incident identified on October 14, 2026 in which an unauthorized third party may have accessed data including IBANs [1]. A letter signed by the CEO describes possible access to infrastructure hosting the Waza platform, involving names, work emails and in some cases IBANs, possibly including partners' customers, while it is still unclear whether data were actually viewed or copied [1]. fuitededonnées.fr advises verifying any request to change bank details through another channel such as a known number, and being wary of unusual invoices with urgent payment demands [1].
This event has not been officially confirmed. Content is based on media or third-party reports.
