help: Reverse engineering a DLL file

reverse dll file ida pro

Hi,
I need help disassembling a dll file. The file is written in C and compiled using MS VC6. Any tips would be appreciated. Can anyone point me to a good disassembler.

HI junglejenny :
What you need is IDAPRO 4.3.. It was posted here not long ago! it is 30 megs .. But is the right tool . You will be able to see the exported routines and there is a graphic tool , a viewer that shows all the functions and their logical connections

ida packed dll

Hi !

Try Soft-Ice for tracing & debuging... IDA doesn't always help to understand code ( for example packed executable etc ), but IDA is GREAT TOOL! Must have ))

Good luck

reverse engineering a dll file

I have a problem with IDA PRO. After conversion the file from HEX to ASM. I try to compile it with MASM or TASM i receive a lot of error messages. I this there is a special complier for the ASM file we got from IDA PRo.

W32dasm83 is a uncompeteable tool ! very great for windows tool but sometime you must donwload the unpacker

ida pro dll compile

Why you need to download the unpacker. Can you explain.

reverse engineering soft ice

Because files are often packed and crypted, so to dissasemble them, you have to unpack / decrypt them first. Go to this links and look for unpackers / decrypters:

hxxp://protools.cjb.net
hxxp://www.programmerstools.org

IDA Pro is NOT meant to produce asm file that can be later assembled. This approach is not recommended even by IDA authors. Check datarescue board for more details.

The real purpose of IDA is to understand the way something works.
