A Massachusetts teenager who reportedly hacked into Paris Hilton's cellphone account has been sentenced to 11 months in prison at a juvenile facility.
The boy is a juvenile under federal law. Prosecutors would not name him or confirm Hilton as a victim, citing federal law that keeps such information under seal in juvenile cases.
The teenager was sentenced last week in US District Court in Boston after pleading guilty to nine counts of juvenile delinquency, prosecutors said.
The charges, for activities over a 15-month period, included hacking into Internet and telephone service providers, theft of personal information and posting it on the Web, and making bomb threats to high schools in Florida and Massachusetts.
While in custody and during two years of supervised release, the teenager is prohibited from possessing or using any computer, cellphone, or other equipment capable of accessing the Internet.
Prosecutors said the teenager's first crime was committed in March 2004, when he sent a bomb threat to a Florida school by e-mail. The school was closed for two days while officials investigated and ruled the threat a hoax.
In January, the teenager hacked into T-Mobile's computer system and took account data on its customers, including Hilton.
This spring, he arranged ''with one or more associates" to make a bomb threat to a Massachusetts school, prosecutors said. They said an investigation of the teen's associates is continuing.
Hilton, a hotel chain heiress, stars on the Fox TV reality show ''The Simple Life."
