Reverse Engineering Win32 Trojans on Linux

Friday, 15 November 2002, 8:02 AM EST

In my last article, Reverse Engineering Hostile Code, I described the tools and processes involved in basic reverse engineering of a simple trojan. This article will offer a more detailed examination of the reversing process, using a trojan found in the wild. At the same time, this article will discuss some techniques for reversing Windows-native code entirely under Linux. As an added bonus, all the tools used in this article are either freeware or free software. They are:

Wine - the Win32 API implementation for Unix;
gdb - our favorite Unix debugger and disassembly environment; and,
IDA Pro Freeware Version - Win32 disassembler (runs on Linux under Wine release 20021007, may run under other versions as well).

Note: Readers who haven't read the previous article, Reverse Engineering Hostile Code, may want to stop and do that now, unless they already have some knowledge of C and assembly language.
