    @trejectt Yep, saw one video where client user was able to extract avtr file w/o encryption. And from other source I found out that it is indeed client-sided. Files on VRC servers are still un-encrypted, and encrypted locally. So if anyone have a backup of previous VRC client version, they can still load and rip. Or wait for someone to decompile VRC and make another tool...

      I downgraded VRChat, but I can’t launch it because a warning message says, "Please update."

          @Real-Visitor what if the connection download is intercepted? what would happen?

          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

            Can someone help me on DM for getting an avatar? i still have the ID of it.
            extracting vrca from cache doesn't work anymore, and assetripper can't load assets folder and shows unity version as 0.0.0a0

            Looking for someone who can bypass avatar encryption. I just need to get a single avatar. Still have the ID of it.

              @avatarofcorn I heard personally they did it because they've started a partnership with Booth, but unsure how true that really is. At least the community had time, but I fear vrchat is certainly gonna turn into Pokechat for vrca's.

              @Hardware98 It was clear as day what the outcome would have been when EAC was rammed down everyone's throats to the protest of nearly forty thousand downvotes on the Canny. Didn't take long for them to charge for what mods and other social VR platforms do for free. Notice how development time now is spent on monetization, instead of fixing bugs and improving the existing system. I suppose the massive layoffs last year were to remove staff members who gave half a damn about the community. The rest aren't talking but you can figure it out from how angry Merlin got. (For those who don't recognize this name, he's the guy who brought us UdonSharp and was hired to overhaul the broken Udon system when he was suddenly fired.)

              @Reym Try setting up a transparent MITM proxy with a self-signed TLS cert. Your mileage might vary, given the ring-0 rootkit on the machine.

                    I know nothing, but I have noticed that while the Avatar is in use a __lock file is created in that path. I cannot do anything with this file, but when unloaded it disappears.

                      So once the file on the cache is encrypted there is no way to revert it?

                            @avatarofcorn Yeah I remember that shit. I also downvoted, I think everyone did. Horrible way the platform is going honestly and it's only going to get worse. Genuinely hope they don't start putting ads in the game, but I see that as the next step. Hopefully people will protest then too.

                                @Linze Idk, if it stores that file temporarily somewhere, then possibly, but not sure.
                                Give 90% that they store the file in ram.

                                        Dumping RAM should give you everything. Anyone want to see if the old Ninja Ripper trick works anymore?

                                        @chocolate It's not. That's not a good source of information.

                                          I doubt it is, there have been several clips floating around of modders and client users still easily able to rip, not to mention there was an exploit where people were using an older version of the game and they were still able to rip, this flaw in the system was quickly patched (IIRC it was within 24 hours actually)

                                          Currently investigating ways to bypass VRC's new encryption on VRCA's and VRCW's. Msg me if you have any leads
