Bouygues Telecom Hacked, Nearly 6 Million Records Compromised

HEROIC analysts identified a data breach affecting Bouygues Telecom, exposing 5,926,224 records as of August 4, 2025. The exposed data includes email addresses, full names, phone numbers, and dates of birth. If you are a customer of this telecommunications provider, the only way to know for certain if your information was included is to scan your email.

Why This Data Is Valuable to Scammers

A real name, phone number, email address, and date of birth give a scammer everything needed to impersonate a telecom provider convincingly. Criminals can use these details to call or text customers directly, referencing their real name and account details to appear legitimate, then push them toward fake billing links or attempt to talk a support agent into transferring a phone number to a new device.

Account Details Involved In This Exposure

• Email addresses
• First names
• Last names
• Phone numbers
• Dates of birth

Why This Matters for Affected Customers

Because a working phone number is involved, affected customers face a heightened risk of SIM swap attempts, where a scammer tries to take control of a phone number to intercept calls and text messages, including one time verification codes used by banks and other services. A real birthday also makes it easier for an attacker to pass basic identity checks when posing as the account holder.

How This Kind Of Exposure Happens

In an incident like this one, records are taken directly from a company's own systems rather than gathered one at a time. HEROIC analysts found this data circulating after it had already been pulled from internal records, meaning it reflects exactly what the provider stored about its customers.

Was Your Bouygues Telecom Account Affected?

The quickest way to find out is to scan your email for a match. If your details appear, be cautious of any unexpected call, text, or email that uses your real name, phone number, or birthday to sound convincing, and contact your provider directly through its official channels before sharing any further information or approving any account changes. Apply the same caution to personal and work email addresses alike.
