Spamming and Invasions

Plishing and Pharming are two terms you should know. Plishing is sending out random email with the option for you to be removed from their list. Usually it sound pornographic, when you reply you email address is added to a list for sale to other companies for spamming. Never reply to these messages. They are generated by a random address generators, with the hope you will respond and prove that the address is real.
Pharming is even more evil. It doesn't require you to respond, but instead routes you to a fake site that looks like the one you requested. Then it records your passwords and other information for a later invasion. It requires real tech skills, but several Pharming have occurred at eBay, google and Weather.com. The site you are routed to looks exactly like the one you request so most users don't know they have been Pharmed. Security measures are being added to browsers which double check the web address against the DNS (domain Name Server) list and if they don't agree you are warned.
