Dynamic Binary Analysis and Instrumentation Covering a function using a DSE approach

Abstract: This talk is about binary analysis and instrumentation. We will see how it's possible to target a specific function, snapshot the context memory/registers before the function, translate the instrumentation into an intermediate representation,apply a taint analysis based on this IR, build/keep formulas for a Dynamic Symbolic Execution (DSE), generate a concrete value to go through a specific path, restore the context memory/register and generate another concrete value to go through another path then repeat this operation until the target function is covered.
