Jared James Abrahams, a 19-year-old Southern California computer student, is facing federal prison for hacking the webcam of Miss Teen USA Cassidy Wolf.
Wolf and a dozen other young women worldwide were hacked and blackmailed with the threat of going public with naked pictured he secretly took.
Abrahams pleaded guilty to four counts of extortion and one count of unauthorized access of a computer. He will serve 27-33 months in federal prison.
Court records show that his victims, which included some minors, were located in Southern California, Maryland, Ireland, Canada, Russia and Moldova.
The plot lasted from early 2012 until June 2013.
