T-Mobile has revealed that it fell victim to a security incident earlier in the week, and details of around 2.3 million accounts were accessed.
The hack attack took place on Monday, August 20, and while T-Mobile stresses that no financial data was taken, it concedes that it detected “unauthorized capture of some information”. The exposed data includes names, billing zip code, phone number, email address, account number and account type, which would be enough for hackers to launch successful phishing attacks.
T-Mobile isn’t really saying a great deal about the incident other than trying to downplay its severity and impressing on customers that it acted quickly to stop the attack. Affecting customers in the US, the hack is not the first time T-Mobile customers have been put at risk; a couple of years ago company data was leaked via Experian.
The notice posted on the T-Mobile website reads:
Out of an abundance of caution, we wanted to let you know about an incident that we recently handled that may have impacted some of your personal information.
On August 20, our cyber-security team discovered and shut down an unauthorized access to certain information, including yours, and we promptly reported it to authorities. 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).
