Reading all process memory to find address of a string variable c#

我的梦境 提交于 2021-02-08 13:25:07
问题 I have 2 programs written in c#, first one called "ScanMe" contains a string variable that contains value "FINDMEEEEEEE", and a double variable that has the value of 1546.22915487. And the other program called "MemoryScan" reads all the memory of the first program. I want to get the memory address of the string variable of that process When i execute "MemoryScan" and reads all the memory of "ScanMe" process, then i try to find the byte array of the string in all the data scanned and i get

问题 So I have been trying to read variables with ReadProcessMemory and finding the adresses in cheat engine worked perfectly, but as soon as I got to programming I encountered some problems. I searched for the ammo and health addresses in cheat engine and the health was a one level pointer and the ammo was a three level pointer. I tried reading the health, but everytime I read it, it returns 0. namespace AssaultCubeTrainer { public partial class MainWindow : Window { [DllImport("kernel32.dll",

问题 I found a code that works perfectly for static addresses. However, how would I change this code so it works for pointers? I need to get value from this pointer: 0x1002CAA70 + 0x10 + 0x18 + 0x0 + 0x18 . It is for 64 bit application. public class Program { private const int PROCESS_WM_READ = 0x0010; [DllImport("kernel32.dll")] public static extern IntPtr OpenProcess(int dwDesiredAccess, bool bInheritHandle, int dwProcessId); [DllImport("kernel32.dll")] public static extern bool

问题 So I'm trying to read Memory out of a running exe with ReadProcessMemory() as you can see in the code provided below. The only problem I constantly run into is that I receive the Error 3E6 / 998 which seems to be NOACCESS but I cant find a solution to fix this. And yes I tried to run the exe in Admin Mode without success... #include <Windows.h> #include <iostream> #include <string> #include <tlhelp32.h> #include <Psapi.h> #include <tchar.h> using namespace std; int id = NULL; HANDLE hProcess

C++ ReadProcessMemory into byte array

半城伤御伤魂 提交于 2019-12-25 02:19:53
问题 I'm attempting to use ReadProcessMemory to read a dynamic amount of bytes into an array and then return it. I simply can't get it to work properly. My current code is... byte *Application::readMemory(DWORD address, int length) { byte *buffer = new byte[length]; SIZE_T bytesRead; ReadProcessMemory(piProcessInfo.hProcess, (void *)address, &buffer, length, &bytesRead); return buffer; } Any help would be appreciated. 回答1: Shouldn't it be ReadProcessMemory(piProcessInfo.hProcess, (void *)address,

ReadProcessMemory fails on some Pages (GetLastError()=299)

问题 I try to read all commited pages of a process (Win7-64). On most pages it works but it fails for a few pages. I cannot explain why. Here is my test programme (compiled x32, tested in Win7-64): #include <windows.h> void main() { HANDLE hProc = OpenProcess(PROCESS_VM_READ | PROCESS_QUERY_INFORMATION,FALSE,GetCurrentProcessId()); SYSTEM_INFO si; ZeroMemory(&si,sizeof(SYSTEM_INFO)); GetSystemInfo(&si); char* buf = new char[si.dwPageSize]; for (unsigned i = 0; i < 0x7fff0; i++) { void* baseOffs =

How to write a Perl, Python, or Ruby program to change the memory of another process on Windows?

孤者浪人 提交于 2019-12-18 12:31:36
问题 I wonder if Perl, Python, or Ruby can be used to write a program so that it will look for 0x12345678 in the memory of another process (probably the heap, for both data and code data) and then if it is found, change it to 0x00000000? It is something similar to Cheat Engine, which can do something like that on Windows. 回答1: I initially thought this was not possible but after seeing Brian's comment, I searched CPAN and lo and behold, there is Win32::Process::Memory: C:\> ppm install Win32:

问题 I'm trying to make a program that read the timer value from Minesweeper. (OS is windows 7 64bit) Using cheat engine I found the base address of the variable, but it changes every time I run Minesweeper. What do I need to do to find out the base address automatically? Does it have something to do with the executable base address? Here's my code: #include <windows.h> #include <iostream> using namespace std; int main() { DWORD baseAddress = 0xFF1DAA38;//always changing DWORD offset1 = 0x18;

问题 I am trying to learn more about how to read process memory. So I opened the "entire memory" of the Firefox process in WinHex and saw the following hex values starting at offset 10000. 00 00 00 00 00 00 00 00 EC 6B 3F 80 0C 6D 00 01 EE FF EE FF 01 00 00 00 My question is Is it possible for a human to interpret this without further knowledge? Are these pointers or values? Is there anything, which is common for different programs created with different compilers with regards to the process
