Adobe Photoshop 7.0.1 TryOut - VBOX 4.6.2
Type : Image Editor - Got It From : Digit CD Dec 2002 Issue - India
Protection : VBox 4.6.2
Tech : Dumping + IAT Fix
Crack :
I can't belive it ... Adobe is giving their program with full features enabled .. Earlier TryOut version doesn't have "Save" which makes it useless.But this version is fully functional [only 30 Day Trial Limit : VBOX]and protected by VBOX.
Thanks Adobe for this ...
Ripping VBOX 4.6.2 :
Photoshop 7.0.1
Real program entry point can be easily found.Just put BPX GetVersion after VBOX shows its BOX and run it ... you will break here ..

015F:00C3FD24 FF15CCD5F600 CALL [KERNEL32!GetVersion]

015F:00C3FD3C 890D5C6F2501 MOV [01256F5C],ECX
Use JMP EIP [EB FE] Trick at address 015F:00C3FD2A and dump it using PEditor.Now use WinHex and edit dumped file and change EBFE --> 33D2
Now our dump file is ok but will not run becoz sucker VBOX have fucked its IAT ... So we must first fix it.
Fixing IAT :
Use ImpRec and select "Photoshop" and enter :
OEP
= C3FCFE - 400000 = 83FCFE
Now click "IAT Auto Search" ... "GetImports"
You can see that many pointers [200 - 300]are not valid .... this is becoz they point to vbox dll files ... which decrypt real API address only when needed.If you read my tutorial on Flash MX ... you can see i gave up the idea of fixing 200 - 300 invalid pointers ...
I need this program [Photoshop] badly ... there should be a way to fix it ... think .... think .... what if i fool vbox ? and make it to decrypt API according to my wish ?
First we must study how vbox does it ....
This is how an API is called ...
015F:00BE82DB
FF1514D0F600 CALL [00F6D014] <--- Some API
015F:00BE82E1 85C0 TEST EAX,EAX
015F:00BE82E3 740B JZ 00BE82F0
In ImpRec it is ptr : 00B6D014
If we go inside ...
015F:02F50000
E81AE60B04 CALL 0700E61F <--- Call Decrypt Routine
015F:02F50005 7D37 JGE 02F5003E
Go Inside the CALL ...

015F:0700E61F 55 PUSH EBP
015F:0700E620 8BEC MOV EBP,ESP
015F:0700E622 83EC10 SUB ESP,10
015F:0700E625 53 PUSH EBX

015F:0700E657 C9 LEAVE
015F:0700E658 C3 RET <---- Return real API Address ...
So my point is that ... after reaching 015F:0700E61F if we press F12 in SICE we land inside real API ... So in ImpRec we can fill this API by double clicking invalid ptr.
Fooling VBOX :
It is seen if we are able to trace from where each invalid APIs are called
...
we can place EIP at that CALL and go inside Decryption routine.And when
we reach at 015F:0700E61F if we press F12 we land inside real API. VBox
does its decryption job nicely ... thinking that API is called ...
No need to execute it just vary EIP and CALL all invalid pointers ... And write down all real API names so that we can fill it in ImpRec. Crazy 200 --- 300 API calls to make ... i did it any way 10 hrs ... But worth ...
My method is realy a tedious one but worth ... take a paper and pen and write down all invalid pointers ... for example :
RVA ptr : 00B6D014 ---> 00F6D014
Now use RAM Editor of WinHex and edit primary memory of "Photoshop"
and search for hex value "14D0F600" .... you can see it at :
00BE82DD
By this we can locate the instruction .... for this API ... Now break
in Photoshop module ... BPX on some API ... i used GetPropA when we are
in Photoshop module ... use this command in SICE ...
r
EIP = 00BE82DB
Note : FF 15 is for CALL ...
Now go inside this and when we reach at 015F:0700E61F press F12 we land
inside real API.Write it down..Like this find all APIs .... First search
it in memory using WinHex and than CALL it using EIP trick ....
Crazy 200 --- 300 API calls to make ... i did it any way 10 hrs ... But
worth ...
Now fill all APIs and fix the dump .... And don't forget to add expots in WinIce.dat file .. for files ...ole32.dll,version.dll, shell32.dll and oleaut32.dll ... to find API names inside SICE. Other wise you will not see any thing ...
Note : VBOX manages 2 APIs differently : GetMessageA and PeekMessageA

These APIs are not encrypted but called inside VBOX .... along with other
CALLS ..
It seems that VBOX is doing some thing when these APIs are called.It is
well known that these two APIs form the backbone of message loop in win32.
ImageReady 7.0.1
Use same method .....
015F:00CF567C

015F:00CF56A8 33D2 XOR EDX,EDX
Use same method as we did ...
So
all you need is enough time and patience .... It is worth ...
Both programs are now fully ripped out of VBOX and working finely on my
PC.And you can use it as long as you wish ... Thanks ImpRec
