This is a screen shot of Outlook Express in normal operation.
This, instead, is the Outlook Express activated with Ghostzilla. Notice that a web page is actually loaded and displayed in the message pane. Without a close investigation, the contents inside message pane looks very much like a normal email.
In the highest level of stealth or invisible mode, images are not shown. But, as you mouse over on a particular image, it will be shown as gray or pale. There is a total of 6 stealth levels available for selection.
You may check out Ghostzilla screenshots gallery to find out other advanced ghostly appearances featured hehe.
Never think that Ghostzilla is your ultimate saver allowing you to happily surf Internet during working hours without getting caught. If you think so, you are absolutely wrong :) In some environments, network traffic is monitored by network administrator. Worse still, if your company network has a proxy server, your Internet usage behaviors are practically tracked. Don’t ever try using Ghostzilla as your weapon to full-time workplace surfing, or you bear the risk hehe.
