Web Browser Extension Script Obfuscation System

Abstract:

A computing device comprising a web browser processes instructions to load, by the web browser, first executable code of a browser extension. The first executable code causes the web browser to load a file, wherein the file comprises file content and metadata. The web browser decodes second executable code from the metadata and processes the second executable code to extract obfuscated information embedded in the file content. The web browser extracts third executable code from the extracted obfuscated information and provides, to a user of the computing device, first browser extension functionality by processing the first executable code and second browser extension functionality by executing the third executable code.
