T-Mobile US informed customers on Thursday that their personal information may have been compromised in a security breach that was discovered and shut down by the company.

The telecom provider’s cyber security team identified and shutdown unauthorised access to certain customer information on August 20 and reported it to the authorities, according to a statement published on the T-Mobile US website.

The company said no financial data, including credit card information, or social security numbers had been involved, and no passwords were compromised during the attempted hack.

However, customers were warned that personal information, potentially including name, billing zip code, phone number, email address, account number and account type, may have been exposed.

A spokesman for T-Mobile told the Motherboard news website that around three per cent of T-Mobile’s 77 million customers could have been affected.

The statement read: “We take the security of your information very seriously and have a number of safeguards in place to protect your personal information from unauthorized access.

“We truly regret that this incident occurred and are so sorry for any inconvenience this has caused you,” it added.
