Some phishers use sites that look similar to popular Web addresses to fool you: http://wwwcnn.com/ is different from http://www.cnn.com/ ! Many people use URL shorteners to make long URLs easier to read or type: but these can be used to hide malicious destinations. If it‘s a shortened URL like a t.co link from Twitter, try putting it into http://www.checkshorturl.com/ to see where it‘s really going.
