More than a year ago, there was a leak of data regarding accounts created on the T-Mobile website. At that time, the company was ordered to pay 350 million of dollars in damages, and in addition, T-Mobile had to invest 150 million of dollars to improve security on its sites. However, it turns out that the site was not completely immune to hacker attacks, as there was another data leak.

The attack earlier this year left hackers with access to information on around 37 million accounts. The information obtained by hackers is to concern names, surnames, dates of birth and telephone numbers of subscribers. According to T-Mobile, however, sensitive data on payment cards or passwords are safe and have not fallen into the hands of criminals.
