BINSEC/SE: A Dynamic Symbolic Execution Toolkit for Binary-Level Analysis

摘要

When it comes to software analysis, several approaches exist from heuristic techniques to formal methods, which are helpful at solving different kinds ofproblems. Unfortunately very few initiative seek to aggregate this techniques in the same platform. BINSEC intend to fulfill this lack of binary analysis platform by allowing to perform modular analysis. This work focusses on BINSEC/SE, the new dynamic symbolic execution engine (DSE) implemented in BINSEC. We will highlight the novelties of the engine, especially in terms of interactions between concrete and symbolic execution or optimization of formula generation. Finally, two reverse engineering applications are shown in order to emphasize the tool effectiveness.
