    Anti-Cheat Research

    Hello all,

    Can't seem to find any other discussion or information about the anti-cheat (or detection methods) that they've implemented to detect cheats. So I guess this thread will be used as a place we can centralize our research as to what we've figured out so far and hopefully get a working bypass. (After typing that out I realize it sounds suspicious)

    I sold my own private hack for a while until I got bored of the game and fell off, things like ESP, teleport, auto-harvest, and some other unique features for PVP etc. etc. I have yet to try it this update since I don't feel like wasting my account but I think we should get some things out of the way first like what we know they're doing.

    Confirmed Detected:
    Modification of the camera's field of view:
    Thanks Jadd for the information:
    They include destination vector and interaction target in the Move packet.
    Bypass: Albion max view detection vector bypass. * GitHub
    Loaded Modules Hashset:
    Thanks again Jadd for this one aswell:
    It creates a list of hashed assemblies that are loaded in the game, which is included each time a SelectCharacter and/or ChangeCluster packet is sent.
    PHP Code:
    // aop.a
    public static HashSet<int_assemblyHashes = new HashSet<int>();

    // aq9.az
    public void StoreLoadedAssemblies(EventData eventData) {
        foreach (var 
    assembly in AppDomain.CurrentDomain.GetAssemblies()) {
            try {
                var 
    fileStream = new FileStream(assembly.LocationFileMode.OpenFileAccess.ReadWriteFileShare.Read);
                var 
    binaryReader = new BinaryReader(fileStream);
                
                var 
    assemblyLength binaryReader.BaseStream.Length;
                var 
    assemblyBytes binaryReader.ReadBytes(assemblyLength);
                var 
    assemblyHash Hash(assemblyBytes);
                
                
    binaryReader.Close();
                
                
    _assemblyHashes.Add(assemblyHash);
            }
            catch (
    Exception) {
                
    _assemblyHashes.Add(-1);
            }
        }
    }

    // ara.a
    public static int Hash(byte[] bytes) {
        var 
    hash = -0x7EE3623B;

        foreach (var @
    byte in bytes) {
            
    hash ^= @byte;
            
    hash *= 0x01000193;
        }

        
    hash += hash << 13;
        
    hash ^= hash >> 07;
        
    hash += hash << 03;
        
    hash ^= hash >> 17;
        
    hash += hash << 05;

        return 
    hash;

    Potentially Detected:
    Cheat engine:
    While I haven't seen anyone verbatim say it's detected it's pretty likely, if anyone does any research into this please be sure to comment.


    Any information is useful, so if you know anything please contribute.

    They include destination vector and interaction target in the Move packet. I have always limited the distance to 10 units and also removed the interaction target if it was further. I've never been detected that way. I modify it directly in the packet before it is sent, so there is no impact on gameplay. Code here.

    There's also this, in case you missed it: Interesting Internal Cheat Detection

    The anti-cheat is really nothing to fear in this game. I generally just check on a throwaway account if there's any new packets being sent in the login process or when I get in-game. Any new detection vector is easy to identify from what I've seen - "what are those weird integers being sent in the SelectCharacter packet?
    Oh, they are hashes of the loaded assemblies."

    Thanks for the information! However, I'm struggling to find any of the methods you've referenced in your post, searching for even just the Hashset data type doesn't return anything from dnSpy, am I missing something?

    The rename obfuscation has been offset after a couple of patches. All of this hash detection stuff takes place in the Albion.PhotonClient assembly.

    As of 13 November 2017 (patch 1.0.340.102503:
    are -> as9
    aq9.au -> as4.au
    aq9.az -> as4.a2

    Ah I see now, all the methods are "obfuscated" using reflection, that's why I couldn't find anything, thanks for the update!

    Also, wouldn't a simple bypass for hash detection be intercepting the hash list from a legit client, then just hard-coding the list with the legit hashes once and remove all code that modifies the list?

    Yes, that's how I do it. Seems to work just fine.

    Something else you can add to your list regarding detection - in the Login packet the client includes an MD5 of some (not all) asset files hashes sequentially. The hashes are created from the contents of the asset after decryption.

    You can see how the decryption and hashing is done here. I used it for my clientless bot and I haven't been banned for that either.

    Inputs (hash of decrypted contents, file name):

    Output (sent in login packet):
    Code:
    28 0A 40 02 CA 71 3A 65 9C 23 0A 06 FD 37 F6 22
    Personally I never modified the asset files, but if you do make sure you check if the input files have changed after each patch.
    I have not seen the order change but I have noticed that new files have been added to the list between some patches.

    EffectAreas.LateUpdate contains zoomhack flagging, flag is sent in `CastStart` request

    Code:
    LocalPlayerCharacterView localPlayerCharacterView = GameManager.GetInstance().GetLocalPlayerCharacterView();
    if (localPlayerCharacterView != null && (this.GameCamera.transform.position - localPlayerCharacterView.transform.position).sqrMagnitude > 1600f)
    {
    	if (++this.o > 5)
    	{
    		PhotonClient.GetInstance().t = 3;
    	}
    }
    else
    {
    	this.o = 0;
    }
    Tea and cake or death?!

    Guys,
    I wonder, why to share all this info to public? Don't you know, that devs also read OwnedCore? (I have evidence.)
    You have your working hacks/zoomhacks/bots etc.? Ok, cool. But don't make their life easier (and my life harder) by posting here.

    We don't make their life easier, since they already know what anti-cheat methods they use ....

    And as head developer of Merlin I can tell you two rules of thumb.... don't use zoom-hack... and use good injector (ex. Minject, developped by EquiFox, one of our team members) that way you are relatively safe (against automated detection) for example we have no confirmed bans by automated way... only one reported guy

    Any code modifications are easier to detect. So any injector is detectable.
    Network packets interception is much safer.
    "Unity engine" uses photon protocol.
    Binary Protocol | Photon Engine
    Just decode it.

    I dont see any way to check it.
