VAC Goes Through Your Files!?
Having looked carefully through valve's cs go terms and conditions, I found nothing on the topic of VAC file inspection. I also checked through the other terms and conditions on numerous games, and still found nothing, which probably means that all the VAC system does is scan running processes on your system, especially those which are, by some means, injected into CSGO.exe. Yeah, well no. After reading on a forum of VAC bans, valve mentions that if you don't know where the cheats are stored, consider reformatting you hard drive before reinstalling the game (you can find this here: https://support.steampowered.com/kb_article.php?ref=4044-qdhj-5691 under "You can not transfer your games or items to a different account" line 5-7)

So this got me interested. I connected to a VAC secure server, inside a virtual machine, whilst running Wireshark in the background. The VAC servers did not connect to my computer directly, going through what looked like a proxy, and then, whilst inside my VM detected a custom made DLL file that I designed to alert me when it was transfered to a server to be compared to a database. And it did. I recorded the Wireshark results, and after later inspection confirmed that it had indeed sifted through my Virtual Hard Drive. Hmmm

Can anyone find me the line in the terms and conditions that I agreed to that gives valve my permission to do this? I'm one of those really wierd people who reads terms and conditions carefully before I agree to them, and I don't tend to miss things like that. Besides, the point of Ts and Cs is to alert customers of ways the (in this case) program affects them and their various devices that interact with the program, and, as far as I can see, valve has not done that...

I look forward to being proved wrong, and in my eyes, valve is innocent until proven guilty. It's a shame that victims of VAC bans aren't.

NB I'm not a lawyer, I'm a programmer, I've probably missed something!

EDIT: I'm not hiding child porn, or terrorist material, It's just that valve is legally required to have my digital signature.

I've just found this:

"Steam and the Content and Services may include functionality designed to identify processes or functionality that may give a player an unfair competitive advantage when playing multiplayer versions of any Content and Services or modifications of Content and Services (“Cheats”). You agree that you will not create Cheats or assist third parties in any way to create or use Cheats."

Yeah, valve, that doesnt ♥♥♥♥ing cut it, processes are different to programs.

Also just confirmed that it was a proxy, not a direct connection, and I've just figured out a way to bypass the system of searching through your files. And valve can do nothing about it, because it has no right to in any way interfere with my system / game experience due to the fact I stopped a feature that doesnt exist. DISCLAMER: I will never use this exploit. I'm just sayin

THANK YOU TO TOELI/AVALANCE FOR ENDING MY CONFUSION!

As far as I know, cheats are ALWAYS modifying only .exe or .dll files and also files that use an extention especially created for one game (you name them).

As far as I know you agree to this by this:

What are you hiding? Child porn? Terrorist material? What???
SNAK THE RIPPER Aug 24, 2015 @ 10:07am 
What do you have againist them doing so? If it filters out more cheaters, it's doing a good job. It's not like valve is some sleezy company looking to get into your computer to cause havoc and steal credit card info, the system is designed to catch cheaters, it serves no other purpose then that.
Hmm very interesting, looking forward to get that information too

Even if he has all that, VAC does not search his harddrive for such items.
The Great Cock Aug 24, 2015 @ 10:07am 
Id actualkly like to know too, if it's anywhere its under some over worded privacy part of the document that people don't understand.

If you're not cheating...you have no reason to fear VAC. It looks for modified game files...that's it...and cheats modify game files.

Well, most of people that answered here don't get the point

Still its against the law not to tell people that your going through their files, that the whole point.

Exactly

I don't get why is this a problem. Itš not like VAC is going through your PC and then sends info to Valve about what po** you watch. It's probably scanning for cheats. If they would be collecting information about people based on their files then yeah that might be a problem, but if it's just scanning for cheats then why make a big fuss about this? Anti-virus also scans through your files, you don't see people making a big deal about that.
Toeli Aug 24, 2015 @ 10:27am 
Well, as far as I know Valve is working like an Antivirusprogramm, running through your whole PC checking for modified files.

Ofc it will not check .jpg .docx. .ptt etc.

It will only search for .dll .exe and other file extentions that are able to be injected into another executable.

Therefore I´m pretty sure that you have nothing to fear.


I would be more worried about the fact that Valve is protocolling your chat and your multiplayer chat.


Anyways, they said that they are following the Directive 95/46 (in Europe, I don´t know the American Law)

Link: http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=CELEX:31995L0046:en:HTML

(I´m no lawyer or so, but I´m pretty sure that VAC is the last thing I´m worried about when talking about Datamining and Valve)

Thats because anti virus tells you it's doing that in it's terms and contitions. VAC doesnt.
