Hacker Pleads Guilty in Clinic CaseVideotaped himself committing the crime
Jesse William McGraw worked under contract at North Central Medical Plaza, which houses surgery centers and medical offices. He made a video recording describing his actions and posted it on YouTube.
The government did not charge McGraw with illegally reviewing or modifying patient records.
McGraw faces a sentence of up to 10 years in prison and a $250,000 for each count. Sentencing is slated for Sept. 16, according to the U.S. Attorney for the Northern District of Texas.
McGraw, who went by the moniker "Ghost Exodus" was a member of the hacking group known as Electronik Tribulation Army. Prosecutors say that in the spring of 2009, he broke into more than 14 computers, including one at a nursing station and another that controlled the heating, ventilation and air conditioning system.
His actions included: installing a program that gave him remote access to the computers, removing anti-virus software, and installing malicious code, known as a bot. McGraw admitted he intended to use the bot to launch a denial-of-service attack on the Web site of a rival hacker group, prosecutors say.
He was arrested in June 2009, just days before he planned to launch the attack, which he called "Devil's Day."
