T-Mobile cybersecurity team activity update

In an update on its website Thursday, T-Mobile shared some details of the incident which occurred on August 20th.

“Our cyber-security team discovered and shut down an unauthorized access to certain information, including yours, and we promptly reported it to authorities,” T-Mobile said.

“None of your financial data (including credit card information) or social security numbers were involved, and no passwords were compromised. However, you should know that some of your personal information may have been exposed, which may have included one or more of the following: name, billing zip code, phone number, email address, account number and account type (prepaid or postpaid),” it added.

“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,” T-Mobile said.

Raft of online security updates

This update on potentially unauthorised access of T-Mobile customer data comes as other major tech firms, including Facebook and Google, share details of inappropriate activity by a variety of web users, with links to numerous groups seeking to spread political propaganda and discontent.

More transparency is being demanded of tech firms, as the scope of actions to steal personal data, or influence important decisions and views is increasingly wide spread.

If tech firms want to retain the support of its users and the various Government’s of country’s they operate in, then they are now expected to take better care of personal and private data, while also being more open and clear about those efforts and other details of their own activity.
