Spanish operator Telefonica was hit in the early hours of 16 July by a security breach potentially exposing the complete personal data of millions of its clients, El Espanol reported. Telefonica told the paper the flaw was quickly fixed and reported to the authorities and that it has not so far detected any fraudulent activity resulting from the failure.
El Espanol claimed that the breach left identity and payment information vulnerable and was similar to a serious failure that in July 2017 hit Spain's LexNET system serving the legal profession, leaving personal data accessible to intruders without a high level of technical skill.
Information exposed to hackers included the fixed-line and mobile numbers of clients, their full names, national ID numbers, home addresses, banks and call and data records, all downloadable as a spreadsheet, the paper reported.
Consumer association Facua first detected the data breach.
