font-family:Arial'>This paper aims to present a methodical framework for
high-level reverse engineering. The methodology is a culmination of existing
tools and techniques within the IT security research community, which presents
ways to identify process operation at a higher-level of abstraction than
traditional binary reversing. Here, we focus our attention on application DLLs
and the functions that they implement and export, which includes process
interactions with other applications and various operating system function
calls. We use existing tools and techniques to derive ways of quickly
identifying how applications are constructed, the functions that they use and
how they use them. Following this high-level reverse engineering, the
researcher is then free to take further steps at reversing specific functions
with the more traditional lower-level binary analysis.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The key tools required and used throughout the methodology
are the Universal Hooker (uhooker) by Core Security Technologies [1], the
Interactive Disassembler (IDA) [2] and the OllyDbg debugger [3]. It is assumed
that the reader is already familiar with these tools. Further information on
these tools and their operation can be found from the references section at the
end of this document.<o:p></o:p></span></font></p>
