hey guys, as some of you may already know, I've been working on an obfuscator for quite a long time. https://www.disguiser.net/


There is still a lot of stuff to improve, but I' like to know, how long it takes an experienced reverser to code a Keygen for this.


 


All features are present in normal mode, so I still have something harder in case this is too easy for you guys :D


 


I'd rate it 6/10, let me know what you think


 


 


PS. it might not be the best nor innovative, but its mine! if you find my hidden messages, you will get something from me :)


(yeah, plural! and PM me for your small gift, once you found them)

You can dump the real file easily too using WinDbg and breaking on LoadModule, dump the buffer (2nd param).

 

Yes. but the dumped file need to be fixed manually...

Unpacked file, keygen and relevant source attached. Very nice challenge! ;)


 


I will respect li0n's wishes and will not make full-featured unpacker available. But I might make examples of each protection feature and explain how to remove it - if and when I have more free time. :)

Well I guess it's easier to know how to deob it once you are able to build test-app; using 1 protection only for each test-app (e.g String Encryption, Cflow, Resource, Method ...)

 

Nice job though !

@Xenocode: I didn't have that luxury. All the work was done based on one and only file from this topic. :)


 


But you're right - it would have been a bit easier, if I was able to make more test apps.
