T-Mobile confirmed last Monday that it has been the victim of a cyberattack. This “unauthorized access” as mentioned by the US mobile phone operator, became known on Sunday, August 15, when cybercriminals contacted the Motherboard technology portal to report that they had assessed the personal data of at least 100 million users.

According to Motherboard, the cyber criminals demanded a sum of six bitcoins ($270,000) in exchange for the personal data of customers who had been exposed, causing a 3% drop in the company’s shares.

In a statement, T-Mobile reported that they were working with security forces to investigate what happened and help protect all data that could be at risk of cyberattack.

About 7.8 million current T-Mobile post-paid customers were exposed to personal data such as their names, social security numbers, and driver’s license information.

However, the mobile phone operator assured that they managed to close the access point through which the hackers managed to enter this data, and reported that the investigations will continue; meanwhile, they recommend their users to proactively change passwords and offer two years of free services to those affected by identity protection.
