Personal data of Orange Cyberdefense customers disseminated online

Posted on a well-known cybercriminal forum, the file could have been just one more leak among many of its kind published every day. But the archive posted publicly by a forum user on Sunday, September 4, contains the personal data of around a thousand customers (including the Le Monde group) of the Micro-SOC Endpoint solution, marketed by Orange Cyberdefense. It is therefore particularly sensitive: the leaked lists the surname, first name, telephone number and e-mail address of the IT manager of the companies affected, that is to say of people whose part of their job is precisely to ensure their cybersecurity.

The author of the text that accompanies the publication thus offers users free access to a file counting, according to him, “1,584 Orange Cyberdefense customer data”. This figure actually corresponds to the number of lines in the document and the exact number of customers affected remains unknown, Orange Cyberdefense citing “several hundred customers”. In addition to personal data, the author of the message also claims that “access to their servers is also for sale”without giving more details on the nature of this offer.
