T-Mobile Continues to Investigate Hacker Data Breach Claims

T-Mobile is still investigating a claim that hackers swiped a large amount of data from the company's servers. 

On June 6, a message was posted on the Full disclosure mailing list in which attackers claimed to have hacked T-Mobile and stolen information. In the message, the alleged hackers posted a massive amount of data that, if their claims are true, may only be the tip of the iceberg. 

"We have everything—their databases, confidential documents, scripts and programs from their servers, financial documents up to 2009," the message read. "We are offering them for the highest bidder. We already contacted with their competitors and they didn't show interest in buying their data—probably because the mails got to the wrong people—so now we are offering them for the highest bidder." 

It remains unclear whether or not the data is accurate and the hackers' claims are legitimate. When asked, T-Mobile spokespeople would not confirm that a breach had occurred but stated that the company was investigating the matter. 

"The protection of our customers' information, and the safety and security of our systems, is absolutely paramount at T-Mobile," a spokesperson said in an e-mailed statement. "Regarding the recent claim, we are fully investigating the matter. As is our standard practice, if there is any evidence that customer information has been compromised, we would inform those affected as soon as possible."
