The personal data of Orange customers has been stolen for the second time in over two months, the company has confirmed.
1.3 million French customers had personal details including names, email addresses and phone numbers stolen, in what the company fears will lead to future phishing attempts.
A statement by the company alerted the customers that the stolen info may be used to phish them through emails and SMS, to get into their more sensitive data such as bank account details.
Orange reportedly came to know of the breach in April but delayed its announcement to carry an internal analysis.
Customers unamused by the disclosure took to Orange's Facebook to express their displeasure and ask questions.
An Orange talking to the BBC said: "For the people concerned, the data recovered includes their first names and surnames.
"In addition, depending on the information supplied, email addresses, mobile and fixed-line phone numbers, the identity of the person's internet operator and their date of birth, were also recovered."
The representative said that action has been taken to correct the "relevant technical dysfunctions and to prevent any new illegitimate access to this data".
In February this year, hackers attacked the "My Account" page of 800,000 Orange customers, stealing their personal data.
