Explanation

A web bug (also called a tracking pixel or web beacon) is a tiny, often invisible element - typically a 1x1 transparent GIF or PNG - embedded in HTML code. When a user loads the page, their browser silently requests the image from a remote server, allowing the server to log the user's IP address, browser type, and visit timestamp without the user's knowledge. When comparing old and current source code of a website and finding an unexpected tiny image or external resource request, this is characteristic of a web bug used for covert tracking.
