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
by TH3LiV3- 0 replies
- 3.4k 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…

Sharing working loader source :)

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, …

Lock prefix?
by high6- 7 replies
- 4k views
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.

'ello tuts4you and the SnD team, long time I've been here, long time I've been on the net actually, But I gotta ask, is there someone so kind to type me up a simple template-ish C++ code for Dev-C++ for the use with ufmodlib ?

I might post up the intro when It's done, with the according Thanks to ofcourse, if someone gets the template together Cheers,

KeepAlive in C#

- 4.5k views
I have programmed KeepAlive in C# for just to learn what's it all about. I would've liked to make the button flash, i.e. to change color periodically, but couldn't quess how to do it. 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

xor encryption
by Busted- 2 replies
- 5.3k views
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?!? Cheers, Tipidy

MSIL in DllMain?
by high6- 4 replies
- 3.8k views
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.

Redirecting Calls In Another Exe to Custom DLL Function
by Unbekannt1- 2 replies
- 2.9k views
Since my topic got locked on the MASM forums because this might be a malicious attempt..I'll try it here: I hope the title says it all: I want to detour a function in another process after injecting my dll and then detour that function to a function inside my dll. The detours library do it for C++ but how do I it in MASM? I don't see anything logic at first sight when looking at the pcode bytes...I took this from the detours lib can this be used (after translating to MASM of course) to redirect the call? inline PBYTE DetourGenCall(PBYTE pbCode, PBYTE pbJmpDst, PBYTE pbJmpSrc = 0) { if (pbJmpSrc == 0) { pbJmpSrc = pbCode; } *pbCode++ = 0xE8; *((INT32*&)pbCode…

Need help for C

Hi all I'm new here so i'm gonna sum up a little bit. I'm not damn good for coding in C but i'm trying to move on step by step. I did a little keygen template in C using RPN algo but it's a console template and it's not that leet. I'm not a very good coder but i try to do my best. Link to my Console keygen template [RPN] coded in C I've seen of one tsrh keygen and i think it'll be enough for me. It's a "graphical" template with banner and chiptune but i wanna do one without music first. Does anyone have a tutorial and commented source ? Thanks in advance

Compilers which creates PEs
by gamereverser- 1 reply
- 2.7k views
Hello, i am currently doing some testing and wanted to ask if someone knows a list of compilers which creates from source a valid pe-file. For example many interpreters and 'virtual languages' do not create such pe-files where (all?) Microsoft compilers do. Delphi creates pe-files too, etc. Is there anywhere a list of compilers available listing all/ as many as possible which creates pe-file?

I made this library for to help me out with all my tools. Its contains a PE32/PE32Plus parser, some basic PE edit possibilities are included. A C# stream wrapper for ReadProcessMemory and WriteProcessMemory. A class to take memory snapshots of VM layout. A port of LibDasm. Its .NET code so really slow but easy to use. And the beginning of a x86/x64 IAT rebuilder. Most of the code is work in progress so there might be some bugs Anyhow, you are free to use modify and add as you please. Enjoy B_S.Framework.rar
