Josh Holly, 21, faces up to 13 years in federal prison and large fines when he is sentenced, The Nashville Tennessean reported. Sentencing is scheduled for October.
At a hearing Monday, Holly admitted possession of 200 stolen credit card numbers, pleading guilty to access device fraud, and hacking into celebrity MySpace sites so that visitors would receive spam. A site selling cellphone ring tones allegedly paid him more than $100,000 for his services.
Holly was charged with those offenses after he posted racy pictures of Cyrus on the Internet, saying he obtained them by hacking into her MySpace and gmail accounts. The FBI searched his computer, although he was never charged in connection with the Cyrus hacking.
U.S. District Judge Aleta Trauger scolded Holly for going online when one of the conditions of his bail is staying off the Internet. He agreed when the judge suggested he is an Internet addict.
"You just let all your friends know you have no access to the Internet," Trauger said. "This is all for your own good anyway."
