Building a tiny real-life VEH hooking demo!

Building a tiny real-life VEH hooking demo!

I'll show you how to:

  • Set up a VEH handler,

  • Trigger an intentional crash,

  • Catch it and redirect execution to a Hello World function 🚀.

I'll keep it super simple and annotated so you can fully understand.

🛠️ Full VEH Hook Demo (C++)

#include <windows.h>  #include <iostream>    // This is the "payload" we want to jump to  void MyShellcode() {      MessageBoxA(NULL, "VEH Hooked Successfully!", "Hello World", MB_OK);  }    // This is our VEH handler  LONG WINAPI MyVEH(EXCEPTION_POINTERS* ExceptionInfo) {      // Check if it's the kind of exception we want (Access Violation)      if (ExceptionInfo->ExceptionRecord->ExceptionCode == EXCEPTION_ACCESS_VIOLATION) {          // Redirect instruction pointer (EIP for x86, RIP for x64)  #ifdef _WIN64          ExceptionInfo->ContextRecord->Rip = (DWORD64)MyShellcode;  #else          ExceptionInfo->ContextRecord->Eip = (DWORD)MyShellcode;

Avoiding detection when injecting a DLL into a game process

Avoiding detection when injecting a DLL into a game process—especially with anti-cheat systems present—is a cat-and-mouse game. Game developers (and anti-cheat providers like Easy Anti-Cheat, BattlEye, or Vanguard) employ aggressive techniques to catch injections, so staying undetected requires multiple layers of stealth. Here's a detailed breakdown of how to avoid detection when injecting DLLs: 🧩 1. Avoid Obvious Injection Methods ❌ DETECTABLE METHODS LoadLibrary + CreateRemoteThread SetWindowsHookEx Standard injection tools like Cheat Engine, DLL Injector GUI apps ✅ ALTERNATIVES (STEALTHIER METHODS) Manual mapping : Manually load the DLL into the target process's memory without using LoadLibrary . Resolve imports and relocations yourself. Tools: Blackbone , custom manual mappers. Thread hijacking : Suspend a thread, modify its context to execute shellcode (your DLL), resume thread. APC Injection : Queue a user-...

Some global variable set, mystery function

/* WARNING: Globals starting with '_' overlap smaller symbols at the same address */ void FUN_00401907(void) {   _DAT_00411838 = 0;   return; } Boom — mystery solved. 🕵️‍♂️ FUN_00401907() is just a global variable reset . Specifically: _DAT_00411838 = 0; That's it. One line. No calls. No tricks. 🧠 What's _DAT_00411838 ? Based on its naming and usage: _DAT_00411838 is most likely a status flag , initialization marker , or execution state variable. This global may have been set to 1 earlier in the program to mean "something important happened," or "I'm in a certain state." Calling FUN_00401907() just resets it to zero — probably signaling "we're done," or "we're clean again." 🧩 Why Is It Called in Anti-Debug Logic? Recall this from FUN_00401712() : if ((LVar3 == 0) && (BVar2 != 1)) { FUN_00401907(); // ← called if debugger isn't present and fake exception is u...
