One of the biggest measures of Phishing Prevention is that you should never reconfirm your sensitive information with a website without communicating with them first. You should never visit websites from their links displayed in emails. It is better to go through their homepage and then sign in to your account. And if there is an interesting offer in mail, you must send them an email asking them the details. This is where you will know for sure whether you are being phished or not. The best safeguard against phishing prevention is a cautious user of the online world.
