9:31 ET -- T-Mobile US Inc. is one of the most mentioned companies in the U.S. across all news items in the last 12 hours, according to Factiva data. The American mobile network carrier reported a data breach late Thursday, saying hackers had accessed data such as birth dates and billing addresses for about 37 million customers. The hackers are believed to have had access to the data since Nov. 25, and T-Mobile said it has since stopped the malicious activity. Dow Jones & Co. owns Factiva. (susan.solan@wsj.com)
