These kind of things always scare me. I never could trust saving my card number into any online services because of this.
Unconfirmed Reports of Massive T-Mobile Breach
Early reports indicate that hackers have penetrated the T-Mobile U.S. network and stolen proprietary operating data, customer databases and financial records. According to a post on insecure.org, the hackers have claimed to be auctioning the pilfered data to the highest bidder. T-Mobile competitors, they say, turned them down.
There are no details as to how the hackers achieved the breach, but they did post code to show that they did penetrate the T-Mobile network.
T-Mobile was the target of a masssive 2005 hack, in which Nicholas Jacobsen was charged with unauthorized network access by the U.S. Secret Service. According to published reports, Jacobsen had access to all the information about T-Mobile’s 16 million U.S. subscribers.
T-Mobile subscribers are also the frequent target of e-mail and text messaging phishing scams.
UPDATE: There is no mention of a security breach or incident on T-Mobile’s Web site. We spoke with T-Mobile Saturday night, and they were unaware of the reported incident. They were looking into it, but stil have not provided a formal response.
