Topic created on: October 12, 2005 00:33 CDT by rfreeman .

Over the past two or so months, in my spare time I've been writing a stand-alone PE patch analysis tool. Basically, it occurred to me that such a utility could benefit from providing details about interesting differences at the sub function level. Perhaps similar tools do this--private or otherwise? Anyhow, this forum seemed like the appropriate place to ask for feedback. Essentially I am at a point in development where I have a few options and it would be useful to know if there is a (legitimate) need for this utility which can facilitate batch processing and potentially CSV output. Please note that this utility is not geared towards other types of binary analysis, such as malware analysis.

I have posted an analysis of winsrv.dll from today's update on my blog. Hopefully you find it interesting/useful.

You should check out BinDiff from http://www.sabre-security.com/. It has been around for some time and has reached a very mature stage.

and as you can see their products are very expensive and non-open source , i think RE community needs more and more open source software , have a look at Greg's Thread about analysis tools and their limitations , i really believe that if we could have an open source version of ollydbg community experts would be able to do a good job and change things as they want , as they need , but we dont have anything useful open source around , i know you are looking for technical feedbacks about practical aspects but keep in mind that your tool may help some special people in some special cases but your source code would help everybody to learn , understand and develop good and helpful things , excuse me for this off-topic comment :)

Well, I'm not entirely convinced that this type of software is appropriate for OSS. Although, I appreciate the feedback and I can also appreciate the concern over cost, since to my knowledge, BinDiff also requires a copy of IDA to function.

In responce to Pedram, I was aware of BinDiff when I started on my project. I thought there might be a need for a stand-alone utility with bells and whistles and decided to take up the challenge. Regardless, I appreciate the heads up.
