vac-bypass's Introduction

VAC Bypass

Valve Anti-Cheat bypass written in C.

Getting started

Prerequisites

Microsoft Visual Studio 2019 (preferably latest version i.e. 16.2.5), platform toolset v142 and Windows SDK 10.0 are required in order to compile VAC Bypass. If you don't have ones, you can download VS here (Windows SDK is installed during Visual Studio Setup).

Cloning

The very first step in order to compile VAC Bypass is to clone this repo from GitHub to your local computer. Git is required to step futher, if not installed download it here. Open git bash / git cmd / cmd and enter following command:

git clone https://github.com/danielkrupinski/VAC-Bypass.git

VAC-Bypass folder should have been succesfully created, containing all the source files.

Compiling from source

When you have equiped a copy of source code, next step is opening VAC-Bypass.sln in Microsoft Visual Studio 2019.

Then change build configuration to Release | x86 and simply press Build solution.

If everything went right you should receive VAC-Bypass.dll binary file.

Loading

It is mandatory to strictly follow each step of loading in order to make bypass work.

Method 1:

Close Steam client if open.
Disconnect from the internet.
Run Steam as Administrator.
Inject VAC-Bypass.dll into Steam.exe process.
After successful injection messagebox saying Initialization was successful! should appear.
Reconnect to the internet.
Press Retry in steam window saying 'Could not connect to Steam servers'.

Method 2:

Close Steam client if open.
Compile and run VAC Bypass Loader

Experiment

Bypass has been tested with CS:GO game and Cheat Engine cheating program attached to the game process.

Without bypass:

VAC Error, then VAC Ban within an hour.

With bypass:

No VAC Error during play, no VAC Ban at all.

How it works

The goal is to make https://github.com/danielkrupinski/VAC/blob/2eeb40e38d0f0d7b828dbacb663ee00aef15c1ca/VAC/Utils.c#L187 function return false then VAC aborts scan for cheats. It can be done by bypassing this check for example.

vac-bypass's Issues

Don't load steam.exe

Don't injecting in steam.exe

is it completely safe?

you know, things like these are very rare and just sound ambitious. Can I get Untrusted by this? I alr tested VAC, it worked perfectly fine.

I think you just made Steam shut off to update VAC lmfao.

BRUH.
its literally down everywhere, 100% of the world.

The question

Hello Daniel,

I wanna to ask you, it is okay to use VAC-Bypass still? I wanna to try on my prime account.

And do you suggest using VAC-Bypass with Osiris?

And yeah, what are chance to get bannes using this(kinda stupid)?

I appriciate that work you put on Osiris,ESP,VAC-Bypass and other things.
Thanks.

VAC waves

does this bypass prevents vac waves :thonk:

can i make Vac-Bypass using python?

I try to change C by python and write a same project using python what about this idea.

Error on building

Someone can help me ?
I have this error when i press build solution

How does it works?

Just wanted to know does it work.

We inject VAC-Bypass.dll into Steam.exe process.
Start CS:GO
Inject CS:GO Cheat like Osiris.

That's it? VAC-Bypass will take care of rest? No need of cheat modification?

Someone posted it on website

https://www.unknowncheats.me/forum/team-fortress-2-a/380488-is-this-a-thing-now.html.
Can you take it down? so this bypass wont be easily leaked (so Valve wont know this is a thing too)

if i closed steam, do i had to open the loader again?

Doubts Bypass

Hello Daniel

I have some doubts about VAC bypass

Do I have to inject it again whenever I close the steam or restart the pc?
When this Vac Bypass is detecting (I don't know if this will happen), will you let me know here on Github?

Thank you for making this brilliant Bypass available! I'm certainly very grateful! ^^

Convert DLL to Bytes

How can I convert the dll into bytes to use in VAC Bypass Loader?

Got VAC banned even tho all process followed correctly

Please update it doesn't work anymore!

Stuck on 'Connect Steam account: ....'

I followed the steps but when I press retry it just gets stuck on connect to steam acc

pattern question

https://github.com/danielkrupinski/VAC-Bypass/blob/master/VAC-Bypass/dllmain.c#L7-L12
ive seen you do the same thing in your vac-hooks repo, and im interested in what does this pattern lead to and why you patch it
please answer, thanks

patched?

is this exploit patched?

VAC authentication error [all steps followed correctly]

I was using osiris on a new account and got a VAC authentication error, even tho I followed all processes correctly

Bypass Patched?

Question in tittle.

Steam won't complete login process

After doing the injection process steam will say Connecting Steam account but won't finish. Any suggestions?

Detection question

Wouldn't valve be able to detect this as a normal .dll cheat?
They could just manually add this to their VAC system.

I'm just asking since I see this has gotten some attention.

how to inject?

Injector

How to inject? Injector download link please...

Another question, kinda stupid...

Hey there, I might be an idiot but,

If i have this on (and it works, i tested), then can I now use some already detected cheat and still not get vacced?

I get these errors when I try to compile

Hello there
I get the same error in 3 different files.
dllmain.c line 24
Hooks.c line 95
Utils.c line 61
"Unexpected file ending while searching for pre compiled Header. You might have forgotten to add "#include "pch.h"" to the source code."

Hope you can help me.

after retry the account wont load

After I reconnected to my internet the steam client wont connect it just loads infinitely saying:
Connecting Steam Account:

Quick question

Will this work with other VAC games like tf2 and gmod or just csgo?

Confused

What's different beetwen VAC-Bypass and VAC-Bypass-Loader?

Doesnt work or am I dumb?

So I followed the exact steps, but I still have a "Permanent Ban" in CSGO menu and cant start a game? Am I doing it right or am I just being stoopid?

Not working

While playing deatchmatch on prime i get vac error. I run VAC BYPASS LOADER using administrator

Stuck in Connecting Steam Account

When I inject vac bypass dll to steam without internet and turn on internet and click retry its just stuck saying Connecting Steam Account: (account name)...
What am I doing wrong?

VAC Bypass doesn't work anymore

I was using VAC Bypass, its loader, and OTC. This used to work. Now I can't join a server without being disconnected by VAC. I'm not banned yet, but am sure I will be soon.

FIXED

The bypass got fixed at around 10:00 PM (GMT+1) 3/20/2020

REST IN PEACE

Cant get in to steam account while using Vac-Bypass

Its just says like this:
(https://user-images.githubusercontent.com/17620391/68708201-851fb300-0593-11ea-8451-b60d65a49fba.PNG)

Tried both method still prompting vac at the header of csgo main menu

Is there any updates for this program?

Question

Is it up-to-date and can I use it with game like CS 1.6? Can I get VAC for using this buypass and can I get VAC if I use detected cheat with this bypass?

Patched?

Hi i get info that vac bypass is patched. Is that true?

NOT AN ISSUE BUT A QUESTION!

I'm VERY new to hacking and I'm a bit confused as to what this does exactly. Does it:

Bypass VAC so you don't get banned WHILE you're hacking
Bypass VAC so your ALREADY BANNED account can get on?

Your help is appreciated, will close immediately after :)

Hooks manipulating Functions to disable VAC?

You modify the Functions GetProcAddress, GetSystemInfo with this Hook?

So FARPROC is a function pointer.

return (FARPROC)Hooks_GetSystemInfo
So VAC gets a null pointer?

Is this still working?

Is this still working? I am not sure anymore.

is it really needed to cut your internet connection and why?

^^ title.

VAC Banned possibly by VAC-Bypass

I had installed a new copy of windows with no hacks or sources, played csgo for a while legit and then I decided to use Osiris with Vac-Bypass injecting with Zer0memory injector.

So I downloaded all the sources and compiled with plenty of junkcode. Closed steam and launched the VAC-Bypass. As soon as steam launched I got an account alert that I was banned by VAC on csgo. I didn't even get time to open csgo or to inject anything.

I made this thread to see if this was happening to anyone else at this time. If so please tell me about your story. Thanks,

Harvo

Patched?

I've been getting VAC issues the past two days, even my friend that is using this is getting tons of VAC errors etc. We've been using this for multiple months and are wondering if it's still viable.

Is VAC Bypass still works?

I got VAC BAN using VAC Bypass Loader ;/

Bypass working 18/01/2020

I wonder if the Vac - Bypass is working on this date? Thanks Daniel for sharing it with us

Does VAC Bypass Still Work?

I was wondering if it still works been using it since Jun 2020 haven't been banned yet but I get updates from steam to update should I update or no I've already clicked yes so is that an issue or a problem?

Add a Menu.

Hey, add a menu to Question, Apply Bypass? Yes or No.

Unable to build

[HELP] i suck

I just started using visual studio and etc. and i have 0 clue what im doing.
Can someone help me with error "C1010" unexpected end of file while looking for precompiled header.
