A web bug is an alert sent to a person’s screen that causes a trouble in the functioning of a web-based program or system. It appears as a pop up window or small alert window. When a web-user opens the said window, he/she will be alerted about something that’s taking place on the web-site. These “robots” or “spies” are programmed to retrieve information from a system without the knowledge of the web site user. There are many different kinds of web bugs that one could encounter in any web-site, however there are only a few that are truly harmful.

A web bug is a method used to track visitor activity on an email or web page. Web beacons are commonly used by third-party companies to monitor the activity of visitors to a site for the sole purpose of page labeling or web analytics. They may also be utilized for email tracking as well. Web bugs are created by a unique combination of JavaScript code, web font and a pixel tag.

Some of the more common methods of creating a web bug include using a java application, Perl script, HTML code and JavaScript code. JavaScript code is considered less dangerous than the other methods since it creates a smaller problem on execution and does not disclose what’s actually going on with a bug. Web bugs caused by java application bugs will affect how Java applications interact with each other and what kind of security an application provides. For example, a Java application that renders text through a mouse click would potentially cause an error in a non Java browser.
