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:

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

EagleNT.sys

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.

2. Hack Shield Flow
Here is a graphical chart explaining how all the components work together:

Here is a graphical chart explaining how Hack Shield is started:

**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):

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()); 
//////

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.

this is a repost

This is a repost and I already made one.

im Sorry what 0_0

Old is old?

I guess So.

yeah let me find the original

This is some basic information about HShield, the way it works, etc. Of course you need to be much more specific to actually do something with this, and I think it might be a little dated, but HS should still be structured the same way. Unfortunately I wasn't able to find Th4nat0s' Hacksheild Analysis, that one is most recent, so if anyone can find it plz tell me or add it to this thread.

Thanks to headsup for finding the damned thing!

5) 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

6) EagleNT.sys:

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.

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.

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):

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. 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. Keep in mind that you can gain access to hooked functions by stopping the Hack Shield anti-hack service.

some body should ban this guy for ripping off why06
