This presentation is devoted to analysis one of the stealthiest bootkit seen in the wild – Win32/Gapz. The talk will cover not only remarkable features of the bootkit such as custom kernel-mode network protocol implementation, advanced bootkit technique and payload injection functionality but, also, the way the authors of the presentation approached the problem of analysis Win32/Gapz using the tools by Hex-Rays. The authors will demonstrate the usage of Hex-Rays decompiler SDK for building a plugin that aids with performing reverse engineering of position-independent code in Win32/Gapz.
