Defeat Punk BUSTER !!! tut 1

Hi,

Here is a way to defeat punkbuster checks ( I used IDA Pro ).

IDA Pro 4.3 freeware version: http://www.programmersheaven.com/dow.../download.aspx

First we need to find the "%c%c" or "%s NOT_FOUND" string in pbcl.dll:
PHP Code:
.rdata:1005DADC aCC db '%c%c',0
.rdata:1005DACC aSNot_found db '%s NOT_FOUND',0
Then go to the DATA XREF:
PHP Code:
.text:1002696E push offset aCC ; "%c%c"
.text:100269F1 push offset aSNot_found ; "%s NOT_FOUND"
Scroll up to the beginning of the function:
PHP Code:
int __cdecl sub_100250E0(struct _MEMORY_BASIC_INFORMATION Buffer)
It's called like that:
PHP Code:
.text:10033E45 push ecx
.text:10033E46 inc esi
.text:10033E47 push esi ; our usefull string is stored in this register
.text:10033E48 push edx
.text:10033E49 call sub_100250E0
Now we can detour it:
PHP Code:
typedef int ( *PBPerformCheck_t )( int iECX, char **pszESI, _MEMORY_BASIC_INFORMATION mbiArg3 );
PBPerformCheck_t pPBPerformCheck = 0;

int _PBPerformCheck( int iECX, char **pszESI, _MEMORY_BASIC_INFORMATION mbiArg3 )
{
// if the pszESI's first char is |: Files white list check
// if the pszESI's first char is B: Cvar check
// if the pszESI's first char is N: MD5 check
// if the pszESI's first char is E: Key bind check

// Remove stuff

int iReturn = pPBPerformCheck( iECX , pszESI, mbiArg3 );

// Apply stuff

return iReturn;
}

void Hook( )
{
DWORD dwPbclBase = ( DWORD )GetModuleHandle( "pbcl.dll" );
pPBPerformCheck = ( PBPerformCheck_t )DetourFunction( ( BYTE * )( dwPbclBase + 0x250E0 ), ( BYTE * )_PBPerformCheck, 6 );
}
The string also contains the names of the modules/cvars/path ... checked, the AT and LEN value of the MD5 checks, and this code is 100% working for up to date FarCry 1.4 punkbuster client.

Happy filtering
