Phishing
From Computing and Software Wiki
Phishing is a form of online identity theft that uses spoof e-mails and fraudulent web sites, among other techniques, to lure people into divulging personal and financial data such as: credit card numbers, account usernames, passwords and social security numbers.
Phishing attacks are aptly named because of the similarities they share with fishing. The criminals who are phishing for information are like fishermen and the victims are the fish. The criminals use several different methods to lure their victims into falling for an attack, just like fishermen uses bait to lure fish.
Phishers use the internet as a means to commit fraud. They may use the information they aquired to create fake accounts in the victims names, or make purchases using their credit cards. Often time phishers will sell the information they gather rather then use it.
