Phishing Emails pretend to be from a Legitimate Bank, agency or even

eBay!

“Phishing" spam messages use legitimate 'From:' email addresses, logos, and links to

reputable businesses such as AOL, PayPal, Best Buy, EarthLink and eBay in the message. But

the message instructs you to click on a web link that sends you to a fake website where you are

asked to provide personal information to the scam artists. If you click on a link in an e-mail message from a company be aware that many

scam artists are making forgeries of company's sites that look like the real thing. Beware the

entire Email is one big link to steal information from you!

What to do if you think you have responded to one by

accident

If you have provided your personal information in response to a phishing email, you should assume that you will become a victim of identity theft.

If you provided your bank account or credit card number, you should cancel that account and open a new one immediately

Phishing can occur

By Phone
