Abstract

Browser extensions are small add-ons for the browsers that make everyday browsing faster and easier. System permissions make these extensions powerful and easy target for attackers. Many extensions seem perfectly safe when first installed but quietly turn malicious through updates down the line. Most defenses catch threats before installation of these extensions but fail to detect threats once an extension is already running on user’s browser. Extensions can dodge security checks by sneaking in harmful updates, quietly grabbing extra permissions, or waiting to activate their harmful behavior until later. COMBAT is a continuous monitoring system that sits inside the browser and keeps watching extensions even after their installation. It keeps an eye on updates, monitors permission shifts, and watches how extensions use the network and browser APIs to identify any suspicious activity. Unlike existing tools that only check extensions upfront, COMBAT provides ongoing protection in the background. The proposed monitoring system works alongside existing security tools.
