cracked5pider/stardustUm modelo de implante moderno independente de posição para 32/64 bits
Um template moderno e fácil de usar para shellcode 32/64 bits.
resolvendo módulos da PEB usando 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;
}
resolvendo APIs de funções usando a macro RESOLVE_API ou a função 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 );
A macro RESOLVE_API é um wrapper em torno de resolve::api que automaticamente faz hash do nome da função e converte o ponteiro da função para o tipo de função.
hashing de strings tanto para UTF-8 quanto para UTF-16 usando a função expr::hash_string em tempo de compilação:
auto user32_hash = expr::hash_string<wchar_t>( L"user32.dll" );
auto loadlibrary_hash = expr::hash_string<char>( "LoadLibraryA" );
suporte a strings brutas para 32/64 bits usando a função symbol:
auto caption_string = symbol<const char*>( "hello from stardust" );
user32.MessageBoxA( nullptr, caption_string, symbol<const char*>( "message title" ), MB_OK );
fácil adicionar novas APIs e módulos à instância. No arquivo include/common.h, a seguinte entrada deve ser feita:
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
};
...
enquanto o arquivo src/main.cc deve resolver o endereço base da user32 e resolver o ponteiro da API:
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 );
...
}
capacidades de depuração semi amigáveis via DbgPrint. O projeto, no entanto, precisa ser compilado em modo de depuração especificando make debug. Uso:
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 );
