Abstract

HTML5 is an emerging stack for next generation applications. HTML5 is enhancing browser capabilities and able to execute Rich Internet Applications in the context of modern browser architecture. Interestingly HTML5 can run on mobile devices as well and it makes even more complicated. HTML5 is not a single technology stack but combination of various components like XMLHttpRequest (XHR), Document Object model (DOM), Cross Origin Resource Sharing (CORS) and enhanced HTML/Browser rendering. It brings several new technologies to the browser which were not seen before like localstorage, webSQL, websocket, webworkers, enhanced XHR, DOM based XPATH to name a few. It has enhanced attack surface and point of exploitations for attacker and malicious agents. By leveraging these vectors one can craft stealth attacks and silent exploits, it is hard to detect and easy to compromise. In this paper and talk we are going to walk through these new architectures, attack surface and possible threats. Here are the top 10 threats which we are going to cover in detail with real life examples and demos.
