Deadly Computer Viruses
The creator of this virus received a 20 month jail sentence and a $5000 fine. Generated over a decade ago, this clever piece of virtual disease operated through Microsoft Outlook. This is how it worked: you receive an email titled Here is the Document you asked for from an unknown sender, you got infected as soon as you opened the email, and the virus would replicate and delivers itself to the top 50 people on your list without you getting a hint of it. Some major US government departments were hit and the damage is thought to be around $1 billion at least. A 20 month jail sentence well deserved.
