A man accused of hacking into AT&T's servers and stealing the personal information of more than 120,000 iPad customers was reportedly indicted today.

Reuters reports the alleged hacker, Andrew Auernheimer, was charged with one count of conspiracy to gain unauthorized access to computers and one count of identity theft by a Newark, N.J., grand jury.

The indictment comes after co-defendant Daniel Spitler pleaded guilty last month to the same charges. Spitler could face a sentence of 12 to 18 months of prison, according to Reuters. His sentencing is scheduled for September 28.

The two, part of a hacker group known as Goatse Security, allegedly broke intoservers run by AT&T a little more than a year ago and obtained the e-mail addresses of iPad customers. The alleged act triggered concerns over AT&T and Apple's ability to protect their customers' personal data.

Shortly after, AT&T, which provided the cellular data to Apple's iPad, shut down the vulnerability that led to the breach.
