Phishing is one of the common forms of cyber crimes. It consists in the fact that criminals create fake websites of online banks, payment systems, etc., which are visually indistinguishable from the original. Visitors of these sites usually do not notice the differences between it and give sensitive information - user names, passwords, credit card numbers, etc.
Use phishing filters to protect against phishing threats. A phishing filter is an application, a browser toolbar or web service that checks the safety of a website. Modern browsers (Opera 9.6 +, Mozilla Forefox 3.5 +, Safari) have built-in protection against phishing.
