French telecommunications provider Bouygues Telecom disclosed a cyberattack that led to the exposure of nearly 6.4 million customer records, including 5.7 million unique email addresses. The compromised data reportedly included names, physical addresses, phone numbers, dates of birth, and IBANs, raising concerns about fraud and financial abuse. The company said affected customers were notified after detecting the intrusion into its services.
French electronics retailer Boulanger also suffered a major breach in which more than 27 million rows of data were exposed, including 2 million unique email addresses. The leaked information reportedly included names, physical addresses, phone numbers, and even latitude and longitude data. Unlike the Bouygues incident, the stolen Boulanger dataset was later posted publicly on a hacking forum, significantly increasing the likelihood of downstream misuse, phishing, and identity-related abuse.
