Phishing

In computing, phishing is an attempt to criminally and fraudulently acquire sensitive information, such as usernames, passwords and credit card details, by masquerading as a trustworthy entity in an electronic communication. eBay, PayPal and online banks are common targets. Phishing is typically carried out by email or instant messaging,[1] and often directs users to enter details at a website, although phone contact has also been used.[2] Phishing is an example of social engineering techniques used to fool users.[3] Attempts to deal with the growing number of reported phishing incidents include legislation, user training, public awareness, and technical measures.
