Stardust

قالب شيلكود حديث وسهل الاستخدام 32/64 بت.

يستخدم تجزئة وقت التجميع باستخدام fnv1a لحل كل من الدوال والوحدات

الاستخدام الأساسي

حل الوحدات من PEB باستخدام resolve::module:

if ( ! (( ntdll.handle = resolve::module( expr::hash_string<wchar_t>( L"ntdll.dll" ) ) )) ) {
    return;
}

if ( ! (( kernel32.handle = resolve::module( expr::hash_string<wchar_t>( L"kernel32.dll" ) ) )) ) {
    return;
}

حل واجهات برمجة التطبيقات (APIs) باستخدام وحدات الماكرو RESOLVE_API أو الدالة resolve::api:

const auto user32 = kernel32.LoadLibraryA( symbol<const char*>( "user32.dll" ) );

decltype( MessageBoxA ) * msgbox = RESOLVE_API( reinterpret_cast<uintptr_t>( user32 ), MessageBoxA );

msgbox( nullptr, symbol<const char*>( "Hello world" ), symbol<const char*>( "caption" ), MB_OK );

class instance {
    ...
    
    struct
    {
        uintptr_t handle; // base address to user32.dll

        struct {
            D_API( MessageBoxA );
            // more entries can be added here
        };
    } user32 = {
        RESOLVE_TYPE( MessageBoxA ),
        // more entries can be added here 
    };
    
    ...


declfn instance::instance(
    void
) {
    ...
    //
    // resolve user32.dll from PEB if loaded 
    if ( ! (( user32.handle = resolve::module( expr::hash_string<wchar_t>( L"user32.dll" ) ) )) ) {
        return;
    }

    //
    // automatically resolve every entry imported
    // by user32 from the structure 
    RESOLVE_IMPORT( user32 );
    ...
}

const auto user32 = kernel32.LoadLibraryA( symbol<const char*>( "user32.dll" ) );

if ( user32 ) {
    DBG_PRINTF( "oh wow look we loaded user32.dll -> %p\n", user32 );
} else {
    DBG_PRINTF( "okay something went wrong. failed to load user32 :/\n" );
}

DBG_PRINTF( "running from %ls (Pid: %d)\n",
    NtCurrentPeb()->ProcessParameters->ImagePathName.Buffer,
    NtCurrentTeb()->ClientId.UniqueProcess );

DBG_PRINTF( "shellcode @ %p [%d bytes]\n", base.address, base.length );
