Back from CppCon 2016

Quarkslab was present at CppCon 2016, presenting general thoughts on the C++ optimization process and how much the so-called zero-cost abstraction relied on the compiler implementation, and not on the standard. Now comes a humble report from this great event!

Visual C++ RTTI Inspection

C++ is well-known to be tedious to analyze, the use of both inheritance and polymorphism (i.e. virtual method) makes the compiler generate indirect calls. Usually, this kind of assembly code forces the reverse engineer to execute the code in order to figure out the destination of a call. In fact, we are looking for the VFT (Virtual Function Table). This table contains all virtual methods for a specific instance of a class. This article shows how to retrieve this information to make the analysis of a C++ software easier.
