Enjoy, everybody! http://www.sendspace.com/file/wnbgdq Use it as you want, credits or not; it's not terribly messy, some parts were a bit inflexible (e.g.: The GetFunction function should accept one or two more parameters for the hostname and request to be sent, etc). Otherwise, I think it works fairly well.

Ruby interpreter issues

April 12, 2009 by metr0

Hey, Porting this post to the public area. Anyway, here it goes: I've been writing a small ruby extension which provides to functions in a class, to log some text to Olly's log window and to put a MessageBox on the screen; nothing complex. I then embedded a ruby interpreter into an Olly plugin, hoping to be able to call the extension function from my script. But calling the script using the embedded ruby interpreter causes either an exception or simply doesn't work (with ruby_exec doing nothing). If anyone has been working with an embedded ruby interpreter before: suggestions are welcome. Regards, metr0

How to define local string in MASM?

Just like C function MyProc() { char szTemp[] = "Hello World!" } In MASM: MyProc PROC local szTemp:byte MyProc ENDP The problem is how to transfer "Hello World!" to szTemp, WITHOUT defining global variable in .DATA segment. I figured out one way, but it will not be the best way. MyProc PROC local szTemp[128]:byte mov al, 48h ;ASCII of 'H' mov szTemp, al mov al,65h ;ASCII of 'e' mov szTemp+1, al ;etc... MyProc ENDP Could any buddy suggest me better solutions? Thanks in advance.

Hi all, I've tried unsuccessfully on several occasions to compile C code to a static library so i can use it with MASM, but every time i try, i add the lib file to a project (created just for testing) and try to compile and i get the following error message: error LNK2001: unresolved external symbol _Function1@16I've used extern "C" to prevent the names being decorated, but this doesnt seem to make any difference to the error, as it is identical regardless of the name being decorated or not. I've tried using stdcall, no joy. Does anybody know what needs to be done to succeed with this? Also, i've succeeded in making a static library from a VC++ dll with Dll2Lib (an altern…

VTC Assembly Language Programming

3.5k views

The Assembly Language course is intended for those who wish to write assembly for both Windows and Linux. It uses the freely available NASM assembler, which is feature-complete and produces object code in a variety of formats. The predominant CPUs today use the Intel instruction set, and all examples in the course use that instruction set. The course covers the background information necessary for assembly programming and it covers the forms programs must take to operate in the systems. Some time is spent with low-level I/O, but many of the examples interface with C mainline programs. The emphasis of the course is in writing assembly language functions that can be called …

Hi! I have some problems reversing programs in this kind of scenario: 1)Application uses custom made GUI (graphics user interface), that is made by DirectDraw or similar graphics api 2)There is no references for text, even encrypted ones, just because all text is drawn using images Application must use some sort of way to find out when mouse is clicked, so i could break on that function call and then step code to find what i want. Just i dont know what should i search for. I see that application uses USER32.PeekMessageA and other related messaging functions, im thinking that i could use code cave to create some conditional breakpoint if message signalizes that i have mou…

Here is the loader I built. Might be useful for someone trying to patch some bytes. The code may look like a certain tutorial from arteam. But I can reassure you that it took 3 of us. To make that code work. It took us 5 hours of editing that piece of **** tutorial that arteam built to make it work properly. So here is working code as of May 30th 2009. Can be used for games or programs to patch certain memory addresses. #include "stdafx.h"#include "windows.h" #include "string.h" void GetLastErrorMsg(char *szBuf) { // DWORD szBuf; LPVOID lpMsgBuf; DWORD dw = GetLastError(); FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, …

What is this used for? And is there C++/C code that when compiled uses this(to give a better understanding of it)? I checked the help file but I don't really get what it is used for. Is there an unlock? I am probably getting confused due to the lack of knowing more about how the cpu/etc interact, etc.

Any advice is welcomed. The program displays a dialog window with a single button that I shuld've wanted to blink or to change color to attract a user's attention. The EXE-file is to be found in BIN directory (RELEASE or DEBUG). To compile the project, MS .NET Framework 3.5 and MS Visual C# 2008 Express Edition are needed. Please notify me of any changes to the source code. KeepShadowDefenderAlive.rar

Hi all, Whilst I am coding my first keygen me, I thought I might experiment with a bit of simple xor encryption. I have done a bit of research and want to double check to see if I understand this, example code below: mov eax, 15 mov ecx, 20 xor eax, ecx mov eax, offset Buffer xor eax, eax xor ecx, ecxNow... 15 xor 20 = 27, therefore would 27 be stored in the buffer according to this code?!?

I currently am getting around it by doing CreateThread(0, 0, (LPTHREAD_START_ROUTINE)Init, 0, 0, 0); But from what I understand, when you create a thread in DllMain it queues it up to be executed after DllMain executes. So how can I have a MSIL DeInit function? Creating a thread wont work because it will execute after the dll is no longer in memory.
