INX file help

[sumerboard]

I have a .inx file I have decompiled and believe I have found where the security lies, but I am unsure as to what to look for and change to bypass this. Any help or guidance toward cracking inx files would be greatly appreciated.

I won't give you complete walkthrough - that won't make you think and learn. But here is little sample that should get you started:

@00015238:0020 MovingToMinneapolis15(local_string6, global_string67, global_number69, global_number70); // dll: ISOLS32.dll
@0001524A:0006 local_number10 = LASTRESULT;
@00015254:000D local_number10 = (local_number10 = 0);
@00015263:0004 if(local_number10) then // ref index: 2
@0001526F:0021 function_744("Invalid installation code.", -65534);
@00015297:0007 local_number1 = (local_number1 + 1);
@000152A6:000C local_number10 = (local_number1 >= 3);
@000152B5:0004 if(local_number10) then // ref index: 1
@000152C1:0006 local_number6 = 1;
@000152CD:003A UnUseDll(global_string70);
@000152D4:0021 function_7("You have entered an incorrect serial number/installation code combination. Please contact technical support", -65533);
@0001534E:0001 endif;
@00015350:0005 goto label_1547a;
@00015359:0009 endif;
@0001535B:000D local_number10 = (global_number64 = 6);

Line 15238-1524A: We call function with 4 arguments. Function is named "MovingToMinneapolis15" and located in ISOLS32.DLL. You can see what arguments are passed and what is does using your favorite debugger. Upon return we get dword in LASTRESULT, we store that in local_number10.
Line 15254: figure out yourself. If you know C, this is no-brainer.
Line 15263: if (badboy) {
Line 1526F-15350: make_badboy_suffer
Line 15359: }
Line 1535B: goodboy code continues...

Other checks are similar but don't use external DLL.

How to bypass these checks? Depends on what you want to achieve..
a) one time installation?
Patch DLL to always return 'good boy' value. Input values that satisfy remaining checks. Or you can try extracting all files from setup package and "install" them manually.
b) patch this setup package?
sid has "patch changes" menu item (never tried using it, though..). If it works, I'd patch line 15254 and maybe few more..
c) make keygen?
Analyze code, try to produce values that satisfy checks in this script and in that DLL.

Cheers,
kao.

Hi all,
looking forward to this thread i found many commons with my problem. How can we find which calls in DLL refered to inx referenced numbers?
A small example would be appreciated.
I mean, what must i do in ollydbg to break into DLL serial functions? Does these numbers refers to memory addresses in DLL or what?

Thanks in advanced

[BfoX]

Use orca to see inside .msi

dear friend i look for more. As i said, i need to know the connection beetween pseudocode calls from inx file and real calls from DLL files. Here is an example:

code from inx file:
NAME = \"Description\"\r\n //-001-/ 0002FF65,
NAME = \"Installation\"\r\n //-001-/ 0002FC69,
NAME = \"Locale\"\r\n //-001-/ 0002FA06,
NAME = \"Manufacturer\"\r\n //-001-/ 0002F674,
NAME = \"Product\"\r\n //-001-/ 0002F7A8,
NAME = \"Serial Number\"\r\n //-001-/ 0002FB34,

/* 0000D239: 000D */ n0015 = g_number000F == 0x00000002;
/* 0000D248: 0004 */ if(! n0015) goto label_00B0; // normal if

/* 0000D25A: 0006 */ s001C = LAST_RESULT;
/* 0000D264: 0014 */ s001C = s001C ^ g_str0063;
/* 0000D271: 0021 */ function_0229("INVALID_HACKED_SERIAL_NUMBER");
/* 0000D296: 0006 */ s001D = LAST_RESULT;
/* 0000D2A0: 0021 */ function_0268(s001C, g_str0062, "Status", s001D);
/* 0000D2B8: 0005 */ goto label_00B1;

My question is: How can i found those calls into DLL files?
what is the reference -for example -0000D254?
I think that all these calls happen into ISRT.DLL file. I 've put some BP's into olly and braked in some API calls but i can't find the connection among them.
Here is the total setup file for reference.

your requested dll files here (http://rghost.net/7jqhMxHkg)

[ektwr]

your requested dll files here (http://rghost.net/7jqhMxHkg)
Thank you for your effort but can you be more specific how to use them? As i noticed, when setup file is opened, it extracts two random name directories into /userAppdata/temp path with full dll's included also those you mention. How can i use them to find the serial number request and bypass it?
PM me also (if you like) to give me more details.
TIA

dont lazzy,

RLSetupValidate.dll have export RLSetupValidate,
PhysicPass.dll heve export PASSGetID,
RLProtection.dll have export RLGenKeyCode and RLValidate,
RLGenUUID.dll have export RLGenUUID_GetUUID and RLGenUUID_EncodeTool,
ProductPassLite.dll have export PASSCheckCode.

It seems that we have different results because i have the nekosuki decompiler. I will try with the sexy intallshield decomp and i will post my results later.
EDIT: I've tried to decompile it with SID ver 1.0 in 3 machines with win8, win7 and xp pro OS but it crashes during process.
Can you send me the decompiler you used and if possible the decompiled inx.txt file too?
TIA

Git thank you for reply but i've already mention that i used exactly the same decompiler and it crashes during proccess.
Anyway, let's say that i've managed to do the decompilation. What next?
I mean, how can i use the patched file in setup proccess? The exe file i gave for reference does extract files in /temp dir and used them realtime. The .cab file which produced is encrypted and i couldn't extraced or even view it so far.
The only hope to bypass the serial number proccess is by tweaking the .inx file produced but i don't know how to use it after and do the installation with no serial nags.
TIA

it crashes during process.

same as you

As Bfox says, he used SID also, and it worked fine. Can you go back one step and tell us what youactually want to achieve?

Certainly. I would like to rebuild the setup file with the patch in serial verification proccess and install it with no serial check. The .inx file can be patched but i dont know how to rebuild the unprotected setup.exe file again.

[Git]

You need to get hold of the installer program that created the .inx, which is Installshield. If you have unpacked to have the orighinal files, you can patch as necessary then recreate the installation package/exe.

Can you link to the setup file/package please?

Thank you for your concern. You can find the link in post #6 in this thread.

EDIT: OK i thought that it wouldn't be easy, am i right? :)

Does anyone made any progress with it? I'm stacked really bad.
