A US man who helped breach AT&T's systems and gather data on more than 100,000 iPad owners has been found guilty in a US Federal court.
The court found Andrew Auernheimer guilty on charges relating to a 2010 breach of AT&T corporate servers. The incident led to the disclosure of some 114,000 email addresses as well as hardware codes for individual 3G iPad units.
Shortly after word of the guilty verdict broke, Auernheimer said that he would be appealing the convictions.
"Hey epals don't worry! We went in knowing there would be a guilty here," he Tweeted.
"I'm appealing of course."
The hacker has said he will remain free on bail until a sentencing hearing is completed.
Auernheimer generated headlines in 2010 when, working as part of the Goatse Security collective, he helped exposed the flaw in AT&T systems. The group claimed that the incident was merely a way of disclosing vulnerabilities in AT&T's systems in hopes of improving security.
Law enforcement, however, did not agree with the claims and in 2011 Auernheimer and another researcher were arrested and charged.
The second defendant in the case, Andrew Spitler, agreed to plead guilty to the charges in 2011.
