Phishing is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by masquerading as a trustworthy entity in an electronic communication. It also can involve phony accounts and scamming. Unlike many other types of Hacking, Phishing instantly snatches a password, no matter how strong the password is.
Communications purporting to be from popular social web sites (YouTube, Facebook, MySpace, Windows Live Messenger), auction sites (eBay), online banks (Wells Fargo, Bank of America, Chase), online payment processors (PayPal), or IT Administrators (Yahoo, ISPs, corporate) are commonly used to lure the unsuspecting. Phishing is typically carried out by e-mail or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Even when using server authentication it requires skill to detect that the website is fake, though it can be easy if one looks at the URL of the page. Phishing is an example of social engineering techniques used to fool and scam users, and exploits the poor usability of current web security technologies. Attempts to deal with the growing number of reported phishing incidents include legislation, user training, public awareness, and technical security measures.
A phishing technique was described in detail in 1987, and the first recorded use of the term "phishing" was made in 1996. The term is a variant of fishing, probably influenced by phreaking, and alludes to baits used to "catch" financial information and passwords. The first use was on AOL, when a user was upset on its customer service so they made an utility (called AOH*ll, uncensored) that would try to hijack users info to get them out of AOL.
