AT&T bug discloses 114,000 iPad owners' e-mail addresses

The issue, which affected only iPad 3G owners, was fixed on Tuesday

IDG News Service - A glitch in AT&T's Web site has exposed the e-mail addresses of more than 100,000 iPad buyers.

The data was downloaded by a hacking group known as Goatse Security, which obtained the information after stumbling upon a program on AT&T's Web site that would send back the iPad user's e-mail address when given a unique SIM card identification number known as an ICC-ID (Integrated Circuit Card Identifier).

By guessing ICC-ID numbers, the hackers were able to download 114,000 e-mail addresses, according to the Web site Gawker, which first reported the news on Wednesday.

"AT&T was informed by a business customer on Monday of the potential exposure of their iPad ICC-IDs," AT&T spokesman Mark Siegel said in an e-mail message on Wednesday. "This issue was escalated to the highest levels of the company and was corrected by Tuesday; and we have essentially turned off the feature that provided the e-mail addresses."

AT&T said the only information hackers could have obtained as a result of this bug was the e-mail address attached to the iPad. That data could have been misused by spammers.

AT&T plans to inform customers whose e-mail addresses were obtained, Siegel said. "At this point, there is no evidence that any other customer information was shared."

There are some pretty powerful iPad users out there, apparently.

After examining the hackers' data, Gawker found e-mail addresses belonging to White House Chief of Staff Rahm Emanuel, New York Mayor Michael Bloomberg and ABC News Anchor Diane Sawyer, as well as addresses belonging to Google, Amazon, Microsoft and the U.S. military.

"The person or group who discovered this gap did not contact AT&T," Siegel said.

Neither Apple nor Goatse Security responded to requests for comment.

iPad breached e-mails, received by Gawker
Gawker published some of the leaked information it said it had received, with key details obscured.

The person or group who discovered the security gap did not contact AT&T.

"We are continuing to investigate and will inform all customers whose e-mail addresses and ICC IDS may have been obtained," AT&T said in its statement. "We take customer privacy very seriously and while we have fixed this problem, we apologize to our customers who were impacted."

Reports said the breach affected only iPad 3G owners. The iPad 3G went on sale April 30.
