Phishing attacks occur when a person sends a fake message that appears to come from a trusted source. Email is the most used method of communication. The purpose is to steal sensitive information such as credit card and login information, or to infect the victim's computer with malware. The phrase phishing was inspired from the word fishing. Phishing is a technique for "fishing" usernames, passwords, and other sensitive information from a "sea" of users, similar to fishing.
