The Phishing Scam:
"Phishing is a modern form of scam in which the artist communicates with the mark, pretending to be from an official organization that the mark is doing business with, in order to extract personal information that can then be used, for example, to steal money. In a typical instance of phishing, the artist sends the mark an email pretending to be from a company (such as eBay). This email is formatted exactly like email from that business, and will ask the mark to "verify" some personal information at their website, to which a link is provided. The website itself is also fake but designed to look exactly like the business' website. The site will contain an HTML form asking for personal information such as credit card numbers. The mark will feel compelled to give this information because of words in the email or the site stating that they require the information again, for example to "reactivate your account". When the mark submits the form (not checking the URL), the information is sent to the swindler."
A Blogging Scam:
"The Ogged Scam: A new con trick born in the age of blogs. For this scam, the con artist creates a pseudonymous internet persona and befriends a group of people online who will become his marks. Then the scammer feigns some terrible disease, such as stomach cancer. Finally, the scammer subtly pushes the idea that his online "friends" could pitch in for something to make him feel better, such as a $700 gift certificate to the French Laundry. After the boon is received, the scam artist claims a miraculous recovery or doctor error."
The Paranoia Scam
"The Paranoia Scam is a scam that involves the con man telling the mark various lies about the different scams and instigating false attempts so that the mark (feeling worried and with no place to hide their money from fraud) turns to the con man for help."
