VRChat added VRCA (?maybe VRCW too) protection
-
so i went out of my way and memory dumped vrchat so if anyone want to look throw it go for it
Download Link (drive.google.com)@crystaldustie pretty cool, lotta data to shift through and sort. Put that bad boy in a hex editor and type "avtr" lmao. Or throw it into WinDbg.
Oh yea thought I'd share this, VRChat creates a __data file in C:\Users\username\AppData\LocalLow\Unity\Temp\
It's an avatar data file. VRChat creates it and instantly deletes it. I set permissions to not allow VRChat to delete files in that folder in hopes it might be some sorta briefly made unencrypted data file, I genuinely believe the VRChat devs would be that lazy to do something like this lol. Unfortunately file is still encrypted, though it's essential to loading the avatar.
Disable VRChat's access to the folder and the avatar throws an error bot.

@Reym run vrchat without eac
@crystaldustie sounds risky, do i just task kill eac as the game starts?
I'm bad at understanding english word
I fix .vrca/.vrcw stuff for free and for fun! Depending on file, every outcome and vary might be different than the original avatar has due to the toggles and much more, send me a pm if you need an avi that need to fix or cracking a password locked avatar or send me .vrca file or through my pms and i will extract/fix them for you!
request is semi-open, only on unencrypted __data file aka .vrca or .vrcw

@Reym u need to just go to vrchat main exe that is in a steam folder and launch that
@crystaldustie
That version of the game isn't very useful because from a server side perspective it doesn't even give the ok to download models that aren't yours, I guess it's ok if you need to rip models that are yours , but I checked the network traffic for this and it doesn't actually send data that isn't yours -
@Reym @crystaldustie @Dr.beep not sure if it is useful but you can still kill the EAC process post launch. still download models, go to public worlds and such. though im sure theres some background service running, however I tried poking around with Process Explorer and didnt see anything related to EAC running.
But I dont think this is useful as injections need to happen pre-launch unless someone has anything they can go off of with this?

Did anyone else see this? Lmao

@StinkerGuy115 lmao what is that
@DeepDishBussy No idea some dude ig showing that they can still rip models post encryption patch. Was poking around google and came across it.

I think the video may have been satirical based on the description
DM me if any of my links go down or if a file is outdated

@DeepDishBussy Honestly I agree, like some edgelord posting their clips of them using a client.
Been really interested in this whole thing myself. I ran wireshark with procmon and compared them to the Output log txt file in the LocalLow folder for VRChat so i can get time stamps of what happens.
There are several servers VRChat communicates with for like authentication. From what it looks like, it seems it just kinda is reading and confirming with a server as it's downloading the files. You find that it repeatedly is checking with a server while it is reading from the __data file.
I did a TCP stream follow of one of the addresses it was communicating with and I saw it initializes by communicating with a "photonengine.io" then it goes to a site called "http://www.digicert.com" and another one by the domain of rapidssl.com
VRChat also around this phase is repeatedly interacting with the PhotoEncryptorPlugin.dll while reading from the __data files in the cache folder. I dont know if any of this is user authentication or actual encryption of the files themself. Can reverse engineer the dll with Ghidra, or just pop it into a hex editor lol.

morals
I know y'all already stopped this conversation, but I would like to add that the "morality" statement and logic behind this is, is hella hypocritical.
It really isn't as simple as saying "Stealing people's edits of their avatars?! Heh, no. I steal from the person who created the model, but under the guise of it being sold to the public, so it's okay for me to steal months of someone else's hard work to even create the model, these people are editing. But don't you dare ever steal something someone else edited to look a certain way, or have a certain drag n drop prefab! Now, let me ride on my moral high horse into the sunset."
Stealing is stealing, period- and Booth avatar creators are not established companies. It is the literal same as stealing a singular person's work. They're literally indie workers using Booth as a platform. If you're gonna try to claim moral superiority about something, maybe that should be just not stealing anything at all.

how the fuck did this thread turn into whatever this nonsense is? Nobody cares about your morals on ripping/leaking, this thread is to get information on cache encryption, not your dogshit takes.
@DeepDishBussy I said this 11 days ago and it somehow is an issue AGAIN. Please stop debating morality in this thread
DM me if any of my links go down or if a file is outdated

@Visaeres Bro reacted to his own comment
its not desperation its fun, and its literally just running 2 simple programs, if you dont understand this stuff just say it and leave 
@StinkerGuy115 2 simple programs? may i inquire more on what you mean or what i could do for that?
I usually like to lurk, dont mind me!

@LeonaTaromati I just meant like running procmon (Microsoft program) and wireshark (packet capture program). Theyre useful tools, simple to use, require knowing what your doing to get anywhere with them. I just kinda poke around with them on my free time to see what I can dig up.
-
@LeonaTaromati but in all honesty if someone is seriously dedicated theyd need to decompile the game itself
Theres so many tools for this, main one is Ghidra. Or something like il2cppdumper on github for the GameAssembly.dll. Even using a hexeditor can tell you a lot.
But the hard part comes in know what to look for and where to look. Youd have to spend some time learning how vrchat works, looking through all the decompiled code in hopes of finding something.
The answer is unknown, could be a simple little trick or it could require making a tool that decrypts the files or anything. who knows. all i know is i like tearing stuff apart and seeing how it works

@brycenBA It makes perfect sense when you don’t agree with people selling models for stupid prices. Spending money on a model for a social game when you’re going to be switching it up nearly everyday or frequently, makes it a waste of money. I stand by what I said. I couldn’t care less about ripping from people that sell avatars because 1) they’re the same recycled boring models (personally they don’t even interest me) and 2) the prices are ridiculous + most of them use recycled assets or secretly kitbash, whether they get caught/exposed or not. When someone puts time and effort to make their own avatars for either themselves or the community to wear and don’t do it for money, then it’s normal to want to respect that. There’s a difference between someone’s work and people that just want to make money with the same boring looking models. Now if the models were actually unique and out of the ordinary then giving them money would be worth it, as long as the price wasn’t insane for what the model was.
Agree with it or not, it won’t change what I think and I know other people think the same.
Personally, I’ve mainly wanted assets or particles or animations on here. Rarely whole models.
This whole thing has attracted people to try and decrypt ripping which is understandable because it’s challenging, but if you people are genuinely going insane out of desperation to rip VRChat avatars and going through all this length just for that, you seriously have issues. Learn Blender and Unity and do something with all that free time that doesn’t involve spending months glued to your screen trying to break through an anti-rip just to steal models you’ll barely wear / get your accounts banned when you could be making 20 models by that time on your own instead.
