Vodafone Group's low-cost operator ho. Mobile announced that hackers stole part of its customer database thus obtaining personal user information and SIM technical data.
The stolen database, offered for sale on dark web forums since December 22, has been partially verified and includes sufficient details to carry out SIM-swap attacks, putting at risk about 2.5 million subscribers.
News of the database being peddled on a hacker forum emerged on December 28 from researcher
Bank Security. An
initial statement from the mobile operator informed that it had no evidence of illegal access to its systems.
This changed on Monday when the
company confirmed the massive breach saying that personal data and SIM-related information had been stolen.
The operator says that the hackers got customers' name, surname, phone number, email, date and place of birth, nationality, and address. They also have the SIM Integrated Circuit Card Identification Number (ICCID) - a unique number providing the card's country, home network, and identification.
