What to watch out for • URLs – Uniform Resource Locator • URL is the address to visit a web site • Domain name translates to an IP address • Can be masked to appear as something different than actual address • Web browser ignores the @ symbol in address • Besides the http://, look for the first “/” • Words to the left of that slash, is actual domain name

  7. What to watch out for • Phishing • Get you to click on link/s with malicious or fraudulent intent • Potential for identity theft • Fake emails from company with whom you do business • PayPal / EBay fraud • Fake charities • Urgent wording • Fake links with legitimate appearance http://office.microsoft.com/en-us/outlook/HA011400021033.aspx

  9. What to watch out for • Email Spoofing • Email appearing to be from someone other than the actual sender • Spamming technique • Creates concern for recipient • Could be sent from infected computer • Open relays • Many ISPs requiring outbound e-mail authentication to keep infected computers from relaying email
