Hacker penetrates T-Mobile systems

A sophisticated computer hacker had access to servers at wireless giant T-Mobile for at least a year, which he used to monitor U.S. Secret Service e-mail, obtain customers' passwords and Social Security numbers, and download candid photos taken by Sidekick users, including Hollywood celebrities, SecurityFocus has learned.

Unnamed in court documents, the informant was an administrator and moderator on the Shadowcrew site who'd been secretly cooperating with the government since August 2003 in exchange for leniency. By all accounts he was a key government asset in Operation Firewall.

On July 28th the informant gave his handlers proof that their own sensitive documents were circulating in the underground marketplace they'd been striving to destroy. He'd obtained a log of an IRC chat session in which a hacker named "Myth" copy-and-pasted excerpts of an internal Secret Service memorandum report, and a Mutual Legal Assistance Treaty from the Russian Federation.

The hacker asked the Secret Service informant for a proxy server -- a host that would pass through Web connections, making them harder to trace. The informant was happy to oblige.
