AT&T Apologizes to iPad 3G Customers for Data Leak

AT&T has sent emails to customers of its iPad 3G data service apologizing for and providing additional information on the exposure of their email addresses and SIM card identifiers last week.

The letter outlines in brief detail how the information was accessed and the company's response once it was notified of the breach. AT&T also reassures its customers that their password and other account information, as well as any data on their devices, are unaffected. It also suggests that the primary risk of the information leak is increased spam and the possible use of such information in targeted phishing tactics attempting to gain additional personal information about customers.

The security breach is currently under investigation by the Federal Bureau of Investigation, which is examining the circumstances surrounding the information exposure and what may have been done with the data obtained.
