Phishing
Phishing is the term used to describe the process of attempting to fraudulently acquire confidential information such as user-names, passwords and credit card numbers by pretending to be a trusted organization that the user recognizes.
Phishing is usually carried out using e-mail or instant-messaging services, and pretend to be from an organization that is well known to the user, such as a bank, online payment processor (e.g. PayPal), auction site (e.g. eBay), social networking site (e.g. Facebook), or even the IT administrator of their employer or ISP. These phishing communications will typically direct users to enter their details at a fake website which bears a strong resemblance to the website of the organization they are masquerading as.
Dangers of Phishing
If a user enters details into a Phishing website, such as their user-name, password, or other confidential information, it will most likely be used by criminals to steal their identity.
