Unpacking DLLs

[TechLord]

nikola:
Unpacking vboxed exes is pretty straight-forward and quite mechanical...Since you yourself are saying that you've not unpacked dlls before, they are quite "involved, and complex", as one of the authors on the forum put it.

If you have tryout version of A*obe Phot* sho* CS or any of the recent ad*be tryout products, you can find at least one or two dll which are vboxed there.
Photosh*p CS has cooltype.dll for instance...( Admins : I hope I am not breaking any of the rules by naming the target since I am not giving any application-specific code here...Please correct me and the post if anything in the post is illegal... )
PEiD will very easily let you find the dlls which are packed.

The problem with not having a generic approach for the dlls, unlike for the
exes , for which we have several generic ones...Is that one dll is very easy to reverse while another takes a whole day...While yet another takes a full week to reverse and find the OEP...

For unpacking the exes ( and even the dlls ) the approach of using SICE with tracex and hydra is given by some of the authors on the net. But it doesn't seem to work very well for dlls though it is quite good for exes.
Moreover, SICE tends to give some stange problem with some programs with system-level drivers and hence, I use SICE only when necessary on an old machine devoted only for that purpose...
The IAT was never a problem for me also for exes, as you mentioned in the post.
It is not so for the dlls. Each dll gives a different problem...Though I'd managed to solve them...Taking a long time...
The ImpRec does a marvellous job and the remaining two imports which it leaves out are always the same and it takes hardly a few seconds to disassemble and find the two. On a fast comp, the IAT-finding for the exes is quite mechanical and takes not more than 15 mins at most. This is all true, of course, if you have the correct OEP...

This is where the problem boils down to ...We have to have a generic method to find the OEP for most if not all of the Vboxed dll also. Onec the OEP is known, then the job of course, becomes much easier...
Using the newer PEiD with the plugin gives the OEP of vboxed exe files correctly ( though I don't find it necessary to use it )...But it says it cannot create process to find OEP or something like that and fails when I give it a dll to find the oep for.

I also have a very bad exam on Monday ! Anyway I'd told you how to get the files...If you don't have access to the tryout versions, then please let me know and I'll mail them to you. It may not be as easy as you think to reverse them and give a generic approach...
