U.S. Secret Service data compromised in T-Mobile hack


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?


  1. Everyone knows you can hack nearly anything linked to the web. It is just the question, is it worth it? This guy probably thought that he was just hacking into civilian files, and then he probably would have got away much more lightly. I would not be surprised if more stuff like this occurs, now with more info on how to defeat encryption and also more information being stored on web-accesible databases. I still do not internet bank, and I dont think i ever shall, this further strengthens my reasons.

  2. Yeah, good post, sry it probably sounded like I’m trying to nullify its reason (by pointing out what was probably very obvious and what noone needed to hear) :S sorry.
