A malicious hacker penetrated the network of mobile phone company T-Mobile USA Inc. and accessed information on 400 of the company’s customers, including sensitive information from the account of a U.S. Secret Service agent, according to statements by T-Mobile and the Secret Service.
In an e-mail statement, the Bellevue, Wash.-based mobile carrier acknowledged that Nicholas Jacobsen, a California-based hacker, allegedly compromised its internal computer systems in 2003 and viewed the Social Security numbers of 400 customers. A grand jury in California charged Jacobsen with one count of unauthorized impairment of a protected computer and one count of unauthorized access to a protected computer, according to a copy of the indictment.
Among the customers affected was a U.S. Secret Service agent who had agency materials linked to Secret Service investigations stored on T-Mobile systems. That information was obtained by Jacobsen but did not compromise any ongoing work, according to Secret Service spokesman Jonathan Cherry.
The unnamed Secret Service agent violated rules that forbid sensitive documents from being copied to other computer systems, Cherry said. He would not comment on whether the agent would be punished for the breach of policy.
There are rumors that the Secret Service data is circulating within the hacker underground.
T-Mobile is obviously responsible for the security of its systems, but what was that guy doing storing sensitive stuff there in the first place?
