This is pretty scary:

Hassan Abujihaad, 32, was found guilty of providing material support to terrorists and disclosing secret national defence information.
He was arrested last year in Phoenix, Arizona.
Abujihaad, a Muslim convert previously known as Paul Hall, faces 25 years in jail when he is sentenced on 23 May.
He showed no emotion as he was convicted of passing classified details of US navy ships to Azzam.com by a jury at the US District Court in New Haven, Connecticut.

Azzam was an Islamist website that prosecutors said had actively supported terrorists but has now closed.
[…]
Abujihaad knew the information he supplied would be used to attack Americans, the US justice department said.
An investigation began in 2003 when police in Britain arrested the Babar Ahmad, a computer specialist working on Azzam, and found a computer disk in his home containing the classified US navy information.
