T-Mobile USA has reported a data breach its fourth in three years. The wireless carrier disclosed the breach last week via its website, saying that it detected and shut down malicious, unauthorized access to some information related to T-mobile accounts. The thieves in this case lifted phone numbers, number of lines subscribed to on accounts, and, in some cases, call-related information . The good news is that the data accessed did not include names on the account, financial data, credit-card information, Social Security numbers, tax ID, passwords or PINs.
