Mimic is a lightweight JavaScript library designed for conducting realistic phishing simulations by creating a fake browser interface on top of an existing webpage without the need for iframes. Utilizing Shadow DOM and MutationObserver technologies, it successfully renders the actual website’s content within a customizable fake browser viewport while preserving original styling and information, enabling more effective testing and demonstration of phishing attacks in a seamless manner. Notable features include a dependency-free design, automatic content injection, and the ability to mimic various browser elements like the address bar and site information.
