Some phishing scams are easily identifiable. Some other phishing attempts through email, social networking, IM, etc. look legitimate. The only way of ensuring you never fall for these scams is by not clicking on links that are sent to you. If you get an email from your bank, don’t just assume it’s actually from your bank. Instead of visiting the links in the email, use a search engine to visit the actual site. This will you will know if you have received a legitimate email or spam.
