• Question 680:

  A common technique for luring e-mail users into opening virus-launching attachments is to send messages that would appear to be relevant or important to many of their potential recipients. One way of accomplishing this feat is to make the virus-carrying messages appear to come from some type of business entity retailing sites, UPS, FEDEX, CITIBANK or a major provider of a common service.

  Here is a fraudulent e-mail claiming to be from FedEx regarding a package that could not be delivered. This mail asks the receiver to open an attachment in order to obtain the FEDEX tracking number for picking up the package. The attachment contained in this type of e-mail activates a virus.
