概述
得到KERNEL32.DLL基址的方法(32bit)
assume fs:nothing ;打开FS寄存器
mov eax,fs:[30h] ;得到PEB结构地址
mov eax,[eax + 0ch] ;得到PEB_LDR_DATA结构地址
mov esi,[eax + 1ch] ;InInitializationOrderModuleList
lodsd ;得到KERNEL32.DLL所在LDR_MODULE结构的InInitializationOrderModuleList地址
mov edx,[eax + 8h] ;得到BaseAddress,既Kernel32.dll基址
FS寄存器指向当前活动线程的TEB结构(线程结构)
偏移 说明
000 指向SEH链指针
004 线程堆栈顶部
008 线程堆栈底部
00C SubSystemTib
010 FiberData
014 ArbitraryUserPointer
018 FS段寄存器在内存中的镜像地址
020 进程PID
024 线程ID
02C 指向线程局部存储指针
030 PEB结构地址(进程结构)
034 上个错误号
_PEB_LDR_DATA结构
typedef struct _PEB_LDR_DATA {

隐藏dll的方法:
到这里,隐藏模块的方法就已经明了了:通过PEB取得Ldr数据,拿到三个模块链表,并将要隐藏的模块断链即可
代码:
BOOL HideMyself()
{
HMODULE hMod = GetModuleHandle( _T( "ntdll.dll"));
HMODULE hModMyself = GetModuleHandle( _T("dll.dll"));
pfnNtQueryInformationProcess p = (pfnNtQueryInformationProcess)::GetProcAddress( hMod, "NtQueryInformationProcess");
PROCESS_BASIC_INFORMATION stInfo = {0};
DWORD dwRetnLen = 0;
DWORD dw = p( GetCurrentProcess(), 0, &stInfo, sizeof(stInfo), &dwRetnLen);
PPEB pPeb = stInfo.PebBaseAddress;
PLIST_ENTRY ListHead, Current;
PLDR_DATA_TABLE_ENTRY pstEntry = NULL;
ListHead = &( stInfo.PebBaseAddress->Ldr->InLoadOrderModuleList);
Current = ListHead->Flink;
while ( Current != ListHead)
{
pstEntry = CONTAINING_RECORD( Current, LDR_DATA_TABLE_ENTRY, InLoadOrderLinks);
//DebugOutW( L"Module:%s, base:0x%Xrn", pstEntry->FullDllName.Buffer, pstEntry->EntryPoint);
if ( pstEntry->DllBase == hModMyself)
{
pstEntry->InLoadOrderLinks.Flink->Blink = pstEntry->InLoadOrderLinks.Blink;
pstEntry->InLoadOrderLinks.Blink->Flink = pstEntry->InLoadOrderLinks.Flink;
DebugOut( _T( "Hide injected dll."));
break;
}
Current = pstEntry->InLoadOrderLinks.Flink;
}
ListHead = &( stInfo.PebBaseAddress->Ldr->InMemoryOrderModuleList);
Current = ListHead->Flink;
while ( Current != ListHead)
{
pstEntry = CONTAINING_RECORD( Current, LDR_DATA_TABLE_ENTRY, InMemoryOrderModuleList);
DebugOutW( L"Module:%s, base:0x%Xrn", pstEntry->FullDllName.Buffer, pstEntry->EntryPoint);
if ( pstEntry->DllBase == hModMyself)
{
pstEntry->InMemoryOrderModuleList.Flink->Blink = pstEntry->InMemoryOrderModuleList.Blink;
pstEntry->InMemoryOrderModuleList.Blink->Flink = pstEntry->InMemoryOrderModuleList.Flink;
DebugOut( _T( "Hide injected dll."));
break;
}
Current = pstEntry->InMemoryOrderModuleList.Flink;
}
DebugOutW( L"rn");
ListHead = &( stInfo.PebBaseAddress->Ldr->InInitializationOrderModuleList);
Current = ListHead->Flink;
while ( Current != ListHead)
{
pstEntry = CONTAINING_RECORD( Current, LDR_DATA_TABLE_ENTRY, InInitializationOrderModuleList);
DebugOutW( L"Module:%s, base:0x%Xrn", pstEntry->FullDllName.Buffer, pstEntry->EntryPoint);
if ( pstEntry->DllBase == hModMyself)
{
pstEntry->InInitializationOrderModuleList.Flink->Blink = pstEntry->InInitializationOrderModuleList.Blink;
pstEntry->InInitializationOrderModuleList.Blink->Flink = pstEntry->InInitializationOrderModuleList.Flink;
DebugOut( _T( "Hide injected dll."));
break;
}
Current = pstEntry->InInitializationOrderModuleList.Flink;
}
//DebugOut( _T("Out HideMyselfrn"));
return TRUE;
}
