Hi, I'm using this code to inject a dll into a process: bool InjectDll(HANDLE hProcess, char * Dll) { size_t AllocSize; void * Alloc; HANDLE hThread; DWORD dwExitCode = 0; AllocSize = strlen(Dll) + 1; Alloc = VirtualAllocEx(hProcess, 0, AllocSize, MEM_COMMIT, PAGE_READWRITE); if(Alloc) { WriteProcessMemory(hProcess, Alloc, Dll, AllocSize, 0); hThread = CreateRemoteThread(hProcess, 0, 0, (LPTHREAD_START_ROUTINE)GetProcAddress(GetModuleHandle("kernel32"), "LoadLibraryA"), Alloc, 0, 0); if(hThread) { if(WAIT_OBJECT_0 == WaitForSingleObject(hThread, 5000)) { GetExitCodeThread(hThread, &dwExitCode); } CloseHandle(hThread); } VirtualFreeEx(h…

(M)ASM <-> C/C++
by unix- 10 replies

Hello, i wanted to ask if someone knows something like a comparison-list of (m)asm and c/ c++ functions. I understand both languages and can write and read it, but a list which compares functions would be nice. What i mean for example: ASM mov eax, value1 cmp eax, value2 //code mov eax, 5 //code mov value3, eaxC if (value1 == value2) { value3 = 5; }Maybe the examples don't match very well but it should be something similar i guess (cant test it right now..). So what i am asking is if there is somewhere a list where i can see how common functions/ instructions look like in asm <-> c? It would be nice to see quickly when i have some asm instructions how the a…

Hello everybody. While trying to create my own patcher with some extended features in Delphi, I created some functions that I could easy Copy-Paste to other patchers, and to ease-up further use. The first one will Patch One byte at a specified Offset: //Patches one byte at a certain Offset. Procedure OffsetBytePatch(AppPath: string; Offset: Longint; PatchByte: byte); var PatchFile: File Of Byte; begin AssignFile(PatchFile , AppPath); Reset(PatchFile); Seek(PatchFile, Offset); Write(PatchFile, PatchByte); CloseFile(PatchFile); end; The second one will Read one byte at a certain offset, for use in eg. checking if already patched. //Reads on byte at a certa…

Function Pointer Member?

I am trying to emulate this assembly in C++ (to make it more readable then a hacky inline assembly). MOV EAX,DWORD PTR DS:[5D91B4] PUSH ESI LEA ECX,DWORD PTR DS:[EAX+89C08] CALL 0047F3F8So I have this psuedo code class MAIN { public: class FUNCLIST { public: bool (* FuncListContains)(int idx,bool) = (bool (*)(int,bool))0x0047EE03; int FuncListGetItem(int idx) { return idx*2; } }; FUNCLIST* FuncList = (FUNCLIST*)(this+0x00089C08); }; MAIN* Main = (MAIN*)0x005D91B4;Of course this doesn't work because the function pointer isn't static. Is there anyway to set the function pointer as a constant but keeping it as a member? Summary: I am injecting…

Hey all! I am working on my first project in MASM at the moment, and it is actually going quite well. Though I ran into a small problem. I want to read a file into memory and save it to another file, with some changes (yeah, I want to encrypt a file), and for doing this I am creating a new procedure. Now, because of everbody has a different amount of memory I let the user define how much bytes they want to be loaded in memory at once for encrypting. The more bytes loaded at once, the less ReadFile has to be called, and the quicker the encrypting will be. But what if the last block of bytes is to be read? (I reach EOF) the lpNumberOfBytesRead parameter should be set t…

Hello all! Some strange error has occured here. I just tried to add a Static element to my DialogBox. The Static element will be shown on a Groupbox, though it is not marked as a child of the group box. The strange thing is that the static element is not showing. I checked it's Style parameters, and everything should be ok. Probably it's something very stupid I'm overseeing right now, but I've been breaking my head for over two hours by now. Here is my Resource File: ;This Resource Script was generated by WinAsm Studio.#define DLG_CRYPTER 1001 #define GRP_CRYPTER 1003 #define GRP_STATUS 1004 #define BTN_OPTION 1005 #define BTN_ABOUT 1006 #define LBL_INPUT 1007 #defin…

If I patch code that a thread could be executing, should I pause the thread first? Or is it safe as long as I use "REP MOVS DWORD PTR ES:[EDI],DWORD PTR DS:[ESI]"? I know using a forloop would definitely cause problems.

[Delphi] Extend last section problems

Hi. I'm trying to make a simple change OEP code, and I've hit a problem. The code works fine on Delphi and C++ apps - that are compiled with FileAlignment as 200h, but with a Visual Basic 6 app - which is compiled with FileAlignment as 1000h the app fails and doesn't work, PEiD also says its an invalid PE. If I manually realign the VB6 file back to 200h with CFF Explorer and LordPE the new OEP works fine. I've read the section on this in the ARTeam PE tutorial, but it didn't cover anything like this. Below is my code, and attached is the patched 1000h file and the realigned patched 200h file. program ChangeOEP_v2;uses Windows, SysUtils;type TByteArray = array of …
