This type of scam uses emails purporting to be from a bank, ISP or other business with which you may do business. The email presents an apparently important reason for you to "confirm" information with them and gives you a link to an official-looking website. Even Simmons own website has been copied for this purpose.
You can avoid most phishing attempts by doing the following:
Be suspicious of emails seeking personal information
Examine web addresses (URLs) in emails to see if they look like legitimate addresses
In general, if a URL appears in an email, type the URL directly into your browser rather than clicking or copying and pasting.
