Security Analysis of Embedded File Systems

Abstract

Embedded devices provide people with an unparalleled level of integration between technology and everyday life. Given the proliferation of these devices, a key question is how secure are these devices that store highly personal information. In this paper I explore the generic structure of embedded devices and conduct vulnerability research. Using the Linux command line and a basic set of tools I demonstrate the process of static file system analysis to find and exploit vulnerabilities in the Trendnet TEW-654TR router.
