It is being reported that on Aug 20th T-mobile was hacked and some customer information was compromised.
Quoting from their announcement…
“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).”
While claiming some of their customers “Important” data did not get hacked, it’s pretty obvious that the information that they did loose in the breach is more than enough to reset user accounts (email addresses and phone numbers) which would let even an unskilled hacker get access to many users accounts.
T-mobile claims that this breach affected less than 3% of its 77 million customers. But as always Renogeek recommends that ALL T-mobile users change their passwords to be on the safe side.
