I have tried unpacking this file using Haoose's utility, and it threw an access violation exception. I was able to unpack it using the UnrealPak.exe tool from Unreal Engine 4; however, the file structure was in tact, the contents of those files was unreadable. Which leads me to believe there is associated key with this file, but I am uncertain and was hoping to gain some insight.

Have you tried my script?

Yes -- I have tried that script with the same results. The files are all extracted, but the contents remain garbled and unreadable as if they were encrypted. I have attached a sample file from the unpacking of the .pak file, which is also seemingly encrypted in terms of content.

The files are encrypted but the script uses the key of Street Figther 5.
What's the real full name of the game? Victory doesn't exist.
Please post the executable.

Oh crap -- I did not realize I titled this using the games code name Victory as opposed to its actual title, The Culling. My apologies...

Open the script and add the following at line 8 under the other AES_KEY lines:

Code:

set AES_KEY binary "bR!@nbR0wnc@rychR!$d@nd@v3d3R3kj!mj0$hk3v!nm!ch@3lm!k3s3@nst3v3t!m"

Let us know if it works.

Sadly that did not work using the unreal_tournament_4.bms script and the provided AES key; which was properly appended of the list of variables to overwrite the old ones.

I've been trying to find the key myself using Olly, but I do not believe I am making any headway...

Edit: ahh it seems the client has updated recently.

Currently that is part of the issue, the fonts are indeed stored in a .uasset format which is Unreal Engine specific. However, they are encrypted, so until you figure that out there is nothing you can do with them. There is a new update coming out tomorrow, so an updated exe file for the client will have to be uploaded for anyone on this forum to take a look at it.

Im curious. Did anyone get any further? - I've been trying tons of things now.

A guy hinted me with the possibility of bruteforcing the key?

Try this key:

Code:

set AES_KEY binary "casd#55@#$%323!$^#b%05sa5W|hhaf4365s52ss51|55m!|{55s^@@36f233|-|0w@%3g8hssDk35/!Nm|_|%ds23%a32d5&23as3%12p|-|y$t3ds562d23fav3c@dyw38#49"

P.S.: the version 0.4.1 of the script allows you to specify any custom key directly by copy&pasting it in the quickbms window, so script editing is no longer required

It worked thanks.

However after the new hotfix it dossent work anymore. But i still got the old one. Now i just have to find out how to read the .uasset files.

You wouldent happen to have a new key? - Its been updated since you proposed the other one. ?

I don't have the game.

The key has not changed, I forgot to report back but after a tip from aluigi, I have consistently been able to find the key via Hex editor. I can verify the above key is still the same and works.
