hree has suffered a massive data breach in which the personal information and contact details of millions of customers could have been accessed. It is believed to one of the largest hacks of its kind to affect people living in Britain.
Here’s everything you need to know about the hack.
UK-based cyber criminals managed to gain access to the upgrade database in Three’s computer system.
The database contains the personal information of those who are eligible for an upgrade, but it is not clear exactly how many customers this includes. The company has not outlined whether the system includes those who have previously upgraded or historic customers that have left the network.
Attackers allegedly accessed the database using stolen employee credentials, which allowed them to login to the system without Three noticing. Once in, they tricked it into sending high-end upgrade handsets to an address where they could intercept them.
Three has not said whether the accessed customer data was also stolen.
What customer details did they access?
Three has confirmed that the data accessed included names, phone numbers, addresses, dates of birth, and some email addresses.
