From Slashdot:
Cyber-criminal Left In Charge of Prison Computer Network
An official in a prison in England decided it would a smashing idea to let a criminal (locked up for stealing money through the Internet) set up a TV system in the prison. To quote the article, "He was left unguarded with unfettered access to the system". The result? He didn't shut down the entire system and leave a trail of passwords that took a specialist company to figure out. Just kidding. That's exactly what he did.
