More of message 1...

More of message 2...

Now do you know which is real?
16
Let’s look at the links.
  • Right-click on the message.
  • Select “View Source”
  • The source code will open in Notepad.
  • Edit -> Find
  • Search for “http”


  • Message 1 Source     Message 2 Source

Link Examples
  • <a href=http://www.topcc.org>
  • <a href=“http:// 211.202.2.79/login.asp”>
  • <a target=_new https://site.com/etc>
  • <img src="http://images.paypal.com/logo.gif”>
  • The URL may or may not have quotes around it.
  • It may have other code between “<a” and “http”.
  • It may be https instead of just http.
  • It may be a link to an image instead of a page.


18
If you are using web based e-mail...
  • You may see something like href=/exchweb/bin/redir.asp? before the actual URL.
  • Just ignore that part and look for what’s after http.
  • Source code for web-based email will have added code.
