Daniel Spitler, a 26-year-old man from San Francisco, has accepted that he accessed customer data of AT&T iPad from the company’s website a year ago and made it public, reported CNET. Spitler was charged with conspiracy and ID theft case.

About a year ago, Spitler developed a script, ‘iPad 3G Account Slurper’. The script was used to get e-mail addresses and unique iPad numbers from AT&T servers in June 2010.

Spitler got data of about 100,000 accounts from the server. The information was later provided to Gawker that published it.

Spitler who surrendered to FBI in January can get up to 10 years imprisonment and $500,000 in fines.

“The magnitude of this crime affected everyone from high ranking members of the White House staff to the average American citizen,” said Michael B. Ward from FBI. “It’s important to note that it wasn’t just the hacking itself that was criminal, but what could potentially occur utilizing the pilfered information,” added Ward who works as a special agent in-charge of the FBI’s Newark Division.

After this incident, the iPad customers were facing the threat of being tricked by anyone to get sensitive data by sending them customized phishing e-mails.

Some of the prominent iPad users who were affected by the breach include White House Chief of Staff Rahm Emanuel, New York Mayor Michael Bloomberg, and New York Times CEO Janet Robinson.
