Web bugs are graphical elements in HTML (web pages, HTML email, HTML usenet message, etc) designed to monitor the reader of that message. They can be something as obvious as a banner or as hidden as a 1x1 pixel transparent GIF. Often the URL is encoded in a manner that identifies the reader and can also be used to place identifying cookies. This is one of the problems with HTML email. Spammers will use web bugs to identify email addresses where the reader has actually looked at the message. And on occasion they will set a cookie to reference the spam when / if the reader later visits the site being advertised. Ximian's Evolution email client handles this by allowing the user to decide if they wish to load images in the HTML email after having read the text. One person reported that their resume on monster.com contained small images of their certifications which were actually web bugs. He could search his web server's log for information on when his resume was being viewed and perhapse by which companies. There has also been some discussion over the integration of the browser and Microsoft Office and the possibility of, say, embedding a web bug in a Word document.
