Your trusted IT guy going rogue is no laughing matter...unless we are talking about this guy. And just to be clear, I didn't start laughing at the list of crap this guy pulled until I got to the porn server part.
You investigate and find that not only is your software illegal, it was sold to you by a company secretly owned and operated by none other than your own IT systems administrator, a trusted employee for seven years. When you start digging into the admin's activities, you find a for-pay porn Web site he's been running on one of your corporate servers. Then you find that he's downloaded 400 customer credit card numbers from your e-commerce server.
