An anonymous post on a security disclosure site claims to have accessed T-Mobile’s databases, financial documents, and other sensitive data. Security experts say much of the information could have been gathered via a penetration test. The wireless provider is currently investigating whether the data and systems are truly in the hands of bad guys. Security expert: “I think they really got into some system and have some documents, but it’s unlikely that they’ve got any worthy information” Security experts said yesterday it may be that the attackers are hyping a smaller breach of some less-valuable information.”]
