Hi there, and welcome to my information dump on Hack Shield, one of the best Anti-Cheat out right now(HAHAH jokes). Today you will essentially learn what Hack Shield is made of, how Hack Shield works, and you will even learn some new bypassing ideas.

1. Hack Shield Components
Hack Shield consists of:
3N.mhe
The Heuristic engine file
Contains the patterns used to search for known hacks
psapi.dll
The process status helper dll
Helps scan process signatures and control process functions
The Hack Shield kernel driver
2. Hack Shield Flow
Here is a graphical chart explaining how all the components work together:

**If I were you I would pay attention to those function names!
3. Bypassing Theory
So, we got some nice information about Hack Shield. How do we bypass it? I will tell you right now, I'm going to show you some very unconventional and new ideas. Say goodbye to your petty API and ASM bypasses, and say hello to your new best friend: detouring. Before we continue, you should have a strong foundation in detouring. If you don't, I recommend watching this: Created by Camtasia Studio 5
So what functions do we detour? In reality, you are going to be detouring CallBack. The CallBack function in Hack Shield collects data from the Hack Shield service. The data is usually errors or "Hack Detected" type messages. The goal of course is to stop it from getting the Hack Detected messages, or stop it from alerting the game client that there is a "Hack Detected" message. The first goal is to find the actual name of the function. The next step is to rebuild the params of the function. The next step is to find the address of this function. Then finally you detour it. Here is my example (not working probably):
OLD SCHOOL BYPASS CODE XD
This is just pseudo code, but hopefully you get the idea. The hard part is finding the address of the function. There are some function addresses included for Combat Arms, but that's just Combat Arms. I have my way of getting it, but I'm leaving it up to you to figure out how to get the address. I don't want to completely hand feed you a working bypass. There are a couple ways to get it.
As a conclusion, I just want to say that you need to use your imagination! Find different functions. Find different ways to bypass. Rip Hack Shield apart.

1. Hack Shield Components
Hack Shield consists of:
- EhSvc.dll
- EhSvc is the Hack Shield interface dll
- It communicates between the game client and Hack Shield
- It communicates with the Hack Shield driver (EagleNT.sys)
- It initiates the hack tool detection engine
- This is usually the only file needed to create a workable bypass
- V3Pro32s.dll
- This is the hacking tool detection interface dll
- This starts the hacking tool detection engine
- This is helps the scanning of known hack signatures
- A very important file. This could interrupt the Hack Shield driver if correctly intercepted

- V3Warp(d)(n)s.v3d
- The anti-hacking engine pattern file
- Not to sure exactly what this does, but it reads the 3N.mhe file
The Hack Shield kernel driver
- Performs anti-hacking functions, protects the game client's process, and hooks certain API's, rendering them useless
- If successfully uninitiated, it could enable the use of many API's and functions such as Read/WriteProcessMemory.

The first goal is to find the actual name of the function. The next step is to rebuild the params of the function. The next step is to find the address of this function. Then finally you detour it. Here is my example (not working probably):
Code:
////// Declares //////
#define CallBackAddy 0x0000001
typedef int ( *PFN_AhnEH_Callback)( long lCode, long lParamSize, void* pParam ); //the name of the function actually is PFN_AhnEH_Callback
PFN_AhnEH_Callback pAhnEH_Callback; //Defining our function
//////
////// Our new function //////
int _CallBackThread()
{
DWORD dwCode = YOUR_CODE_TO_PASS;
int myReturn = pAhnEH_Callback(dwCode, 0, NULL);
return myReturn;
}
//////
////// Our Detour //////
pAhnEH_Callback = (PFN_AhnEH_Callback)DetourFunction( (PBYTE)( Ehsvc + CallBackAddy ), (PBYTE)_CallBackThread());
//////
This is just pseudo code, but hopefully you get the idea. The hard part is finding the address of the function. There are some function addresses included for Combat Arms, but that's just Combat Arms. I have my way of getting it, but I'm leaving it up to you to figure out how to get the address. I don't want to completely hand feed you a working bypass. There are a couple ways to get it.
As a conclusion, I just want to say that you need to use your imagination! Find different functions. Find different ways to bypass. Rip Hack Shield apart.
ok...lol i dont get the codes
nice....info ..... OH yeah
For the two people above me, I somehow doubt this is for script kids like me and you.
TELL HOW TO BYPASS HACKSHIELD ON POINT BLANK PLIZZZ
Lol...good luck you noobs trying to get a bypass..i got one already..They are hard to find these days..gotta make them yourself GOOD LUCK NUMBS
EhSvc.dll
EhSvc is the Hack Shield interface dll
It communicates between the game client and Hack Shield
It communicates with the Hack Shield driver (EagleNT.sys)
It initiates the hack tool detection engine
This is usually the only file needed to create a workable bypass
--------------
not rlly true, using stuff i got rid of Jump_short the main bypass component ._. and there on it was a bypass but that got patched and 2 lazy to update
