| DigitalAcid 11. May 2008 | Hmm, is this one even possible to solve ? 8-) I can patch the "Demo" picture, but that's like aesthetic patching... |
|---|---|
| costy Author 12. May 2008 | In the crackme there isn't any registration routine. So you have to patch. What do you mean with a <patch the "Demo" picture>?? Anyway you can patch it as you like. |
| DigitalAcid 12. May 2008 | Well, i had patched it so the picture was white, so you still couldn't draw anything at that area. Really, i have no idea how to solve this in another way, because everything is done through the MSVBVM or another dll. Now i patched it in another way so you can draw anything in that area. I have uploaded a solution. |
| costy Author 12. May 2008 | I hope you had not reduced Demo picture size... But If can not find other way I can accept this solution. Have you tried to set a breakpoint on picture data?? |
| DigitalAcid 12. May 2008 | Yeah, reducing the picture size is what i did =). I put a BP at the start of first picture byte and some other things, but i really can't find where to make it skip writing the demo picture inside the crackme itself... Patching outside of the crackme (MSVBVM or whatever) didn't really work either. |
| costy Author 12. May 2008 | Hello Digital Acid... 1) Why not make a little of code ingection. Write a dll that saves picture to files then make the program call this dll. It's possibile. Call GetActiveWindow to find the crackme form Call EnumWindows and GetClassName to find the handle of the picture box Save picture to file using a bit of grafic function. 2) Demo picture is painted in the left bottom corner... Make the program paints this picture outside the picturebox area. It's really difficult. Probably I have to change difficulty |
| DigitalAcid 12. May 2008 | Well, i can't really program stuff like that. About point 2, it's in the top left corner (the picture is also hidden inside the crackme) and i thought about that idea, but can't find it or don't know how to do that =). |
| MACH4 13. May 2008 | well I'm useless at VB6 so will look forward to any tutorials on it... |
| costy Author 13. May 2008 | Yes, it is in the left top corner. My English is bad and i wrote "left bottom corner". My mistake. Picture isn't hidden. You can see it with vbreformer. It's inside a picture box : picture2. This picture box is invisible. propriety visible = false. |
| costy Author 17. May 2008 | good! Jim~ and DigitalAcid founded an identical solution. WOW |
| DigitalAcid 17. May 2008 | Lol, we didn't cheat :P. I don't know him at all lol. I would like to see another solution though... |
| Jim~ 17. May 2008 | Haha. Nice. Yeah, I gave up modifying the executable after a few tries. Maybe I need to spend some more time taking a harder look at it... |
| DigitalAcid 17. May 2008 | That's what i tried at first, but finally i had to use this approach too =). |
| costy Author 18. May 2008 | I'm waiting someone who solve my crackme paching the code. |
