Now that you point it out, it occurs to me that you could use this technique to replace just about any system DLL and pwown a box.  Lucky I recommended that you not do this, eh?

Real fun: Creating shim COM objects for which you have no method definitions for.

Meh, it's called IUknown for a reason. by Rogerborg (2.00 / 0) #7 Sat Feb 18, 2006 at 08:55:42 AM EST
This is just a generalisation of what I did to replace ddraw.dll / dsound.dll, in order to pass cloned IDirectFoo objects back to the unsuspecting victim.

Did you have to maintain the original COM object instance?

In my case, we had to have access to in process COM objects outside the process. Fun times.

That brings back memories. by komet (4.00 / 1) #5 Sat Feb 18, 2006 at 08:47:33 AM EST
Back when I was not yet able to have an ejaculation, I made a Windows 3.0 program that prevented the mouse from moving over any Cancel button in a dialog and installed it on various publically accessable computers. The implementation details escape me, but I do seem to recall diverting some calls within the system layer. Perhaps I used a shim DLL, but I really can't remember any more.

I did something like this once... by NoMoreNicksLeft (4.00 / 1) #8 Sat Feb 18, 2006 at 08:57:12 AM EST
Nothing quite as elegant, to be sure. At the time, I was working on something absurd, I think it was a clone of Back Orifice for Mac OS8 (Mac Orifice?), but also trying to hide files from explorer.exe (advapi32.dll maybe?).

At age 31, my quest for world domination is over. I think I'll order pizza.

Pizza is much better than world domination. Well, if it's good pizza. From the pie place on the corner, not Pizza Rut or Dominators.

Did carryout, since the pizza guy does not seem to comprehend that delivery is "delivery". Last time, he sat out on the the street, and honked the horn.

This is after I'd paid the tip via internet, the fucker.

missing functionality by martingale (4.00 / 2) #16 Sat Feb 18, 2006 at 01:52:01 PM EST
Your program also needs to write a makefile, and then you need to write a second program which takes the shim source code and splices into it the contents of a second code file, the latter containing the actual extra shim functionality. Then you can invoke it all like so:

shim_creator && shim_inserter myshimbits.cpp && make

And lo and behold, when the next version of WS_32 is downloaded from Microhard, you don't need to fret about the extra exports they've added because your shim boys don't care.

bonus question: how do you install your system dll while preventing Microblow's dll protection hack from replacing it with the original version?

Bonus answer: you don't.  I'm using this to confuddle individual applications.  What you get up to with system dlls is between you, the Invisible Sky Giant, and the Department of Homeland Security.

Microsoft research by sasquatchan (4.00 / 1) #22 Sat Feb 18, 2006 at 04:48:22 PM EST
provides a full API hook library. Not windows hooks (messages), but a hooking of the full win32 API.

and they'll give you the full source. (or at least the last time I downloaded it [win2k] they would.. great stuff.. )

Put that in your sheapherds pie and eat it!
