The Web is awash with bad seeds who want your money, your data and your sweet, sweet identity. We don't want to scare you -- since these people are the exception, not the rule -- but they are out there. Crafty buggers who prey on trust and carelessness, scammers are not only persistent social engineers, but also skilled hackers who take over Facebook accounts, break into bank databases and spread malware. Using their skills (and sometimes brute force), these crooks have made themselves millions (and potentially billions) of dollars by turning people into their own worst enemies. While we could sit here and spit out a diatribe about avoiding suspicious e-mail attachments or being wary of strange requests from friends, we thought it might be more effective to simply show how some of the biggest (and most successful) scams work their malicious magic, and just how rich the perpetrators got off of careless users.
