Hi, I want to write a little program, which should only consists out of two or three specific functions as i want then to analyse it with ollydbg and see if i can figure it out, how the asm code actually works. Unfortunately i have some problems, maybe someone can help me. I am using Microsoft Visual C++ 2008 Express Edition as my IDE, but the code seems already a little 'overwhelmed' when i wrote a program which only prints hello world. The basic source looks like this: using namespace std;int _tmain(int argc, _TCHAR* argv[]) { cout << "Hello World\n"; system("pause"); return 0; }When i try to analyse this with ollydbg, i get the following message when opening: …

[Help]C++ Dumping a dll's memory

Hey, I'm trying to dump a dll in memory using c++, the actual dumping is fine but I'm looking for help in fixing he virtual addresses. At the moment I am dumping the virtual addresses but need to change them to the offset (i think that's right). I know I'm not being very clear, so I'll post some code. 01E5102A A1 1444E901 MOV EAX,DWORD PTR DS:[1E94414]Of course because I'm not changing the virtual address code, the dump will crash when run (because it will try to mov 1E94414 into eax, which is an invalid address). I'd really appreciate some help, I looked around the forum but couldn't find anything that helped.

I need to modify some source code. I need to get a 2nd string from given string which contains 2 string. The length of 1st string is always changed time to time. For example: NuQW4CSS0Qpa8TnZor in hex: 01 01 01 01 01 01 01 01 1C 01 01 01 01 01 08 4E 75 51 57 34 43 53 53 01 01 01 01 01 08 30 51 70 61 38 54 6E 5Athe 1st string NuQW4CSS (4E 75 51 57 34 43 53 53) it begins with 1 byte in front (08) as the length of the string the 2nd string 0Qpa8TnZ (30 51 70 61 38 54 6E 5A) it also begins with 1 byte in front (08) as the length of the string The problem in the source code i got is, it gets the 2nd string with fixed method, always get it from the 29th byte, which is actually …

Hello, Here's some stuff I have been mucking around with since WinAHX has a tendency to play some AHX tunes completely wrong. This lib is based on Xeron/IRIS's official code, straight from the official replayer and Winamp plugin sources. CPU usage of the library is very small too (around 0-4% on a E2200 dual core). The lib is public domain and is built with MSVC6. Included is the source code as well as a usage example. hvlplay.zip

hi This post is in literate Haskell which means the entire post can be posted into a .lhs file and compiled by GHC. Haskell is a lazy pure functional programming language named after the logician Haskell Curry. http://en.wikipedia.org/wiki/Haskell_(programming_language) http://haskell.org The following code generates a random cd key for an old game, Battlefield 1942. I derived the keygen method with OllyDBG on a random keygen I found on astalavista. Thanks NaG-Scrim/Fighting For Fun - it had good music ;D but your generated code is weird, either msvc6 is not so smart at optimization or your src code is strange, never mind I still made sense of the larger picture. &gt…

Dll injection + message loop

January 7, 2009 by Killboy

Hi I'm injecting a Dll into a process, the Dll then creates an empty window (creating a new class + Createwindow). In my main process, I find the window with FindWindow(ClassName, NULL) and send WM_COPYDATA to it with the stuff it needs to handle. The problem is that I need a message loop for my window to receive messages sent to it. If I create the window and start the loop in DllMain (on DLL_PROCESS_ATTACH), I never return, thus I can't check if the Dll injection worked. (I could check if the window existed, but I dont really like that) So I created a thread from DllMain, in which I create the window and loop the messages. This works, but it feels weird. I wanted…

How do you do something like ModuleHandle.ResolveMethodHandle(token); in cecil? Assembly.MainModule.MemberReferences doesn't contain all the references. Only way I can think is by loading each referenced assembly and check it. Would be very very slow though... (also locating the assemblies...)

SendMessage in a debugger in another thread

Hi, I was trying to inject a dll into a process and use WM_COPYDATA for sending the data needed for the dll to work. The problem is that I'm in the middle of the debug loop, ie the remote thread on LoadLibrary doesn't return until I loop through WaitForDebugEvent/ContinueDebugEvent. So I called it in another thread, and found something weird happening: When I call SendMessage (logging something to a listbox) in the thread, it doesn't return and seems to hang up. At the same time, WaitForDebugEvent hangs up as well, and doesn't return (it's set to INFINITE). I found this at MSDN but I'm probably too retarded to get it... The thread sending the messages waits for SendMessa…

Using WIN32 APIs

Last night I decided to try and see if it was possible to create a messagebox in VB6 without using the built in MsgBox function. I chose to do this because the MsgBox function actually calls rtcMessageBox() located in the MSVBVM DLL. I wanted my application to instead of using this function, use the MessageBox function located in USER32.DLL. The Link below takes you to my source code on how i did it. It was done by executing some pre-compiled ASM that is executed from VB. In order to see what the ASM is doing, compile the program and debug it using Olly. Then place a BP on CallWindowProcA. Run the application, when it breaks... right click on ESP+4 (PrevProc) and se…
