A week doesn't go by now that I don't receive a fishy email. An email that appears to be from my email service or bank that carries an anxiety inducing message. Now that it's tax time I even got an email that looked like it came from the IRS! These are all phishing scams.
Merriam-Webster's definition of phishing: a scam by which an email user is duped into revealing personal or confidential information which the scammer can use illicitly.
Your first line of defense is to NEVER CONFIRM YOUR PASSWORD IN AN E-MAIL OR THROUGH A LINK IN AN E-MAIL. If you discover that you've unwittingly succumbed to a phishing scam, here are some resources at your disposal:
