Easy Anti Cheat Known Common Issues and Fixes

What is Easy Anti Cheat?

Easy Anti-Cheat, developed by Kamu, is an anti-cheating tool designed to stop (and catch) cheaters in online multiplayer games. Think of it like a more modern replacement for PunkBuster, the anti-cheating application that debuted in 2001. Easy Anti-Cheat runs on both Windows and macOS, and various linux machines.

Kamu won’t explain exactly how EasyAntiCheat works—after all, it doesn’t want cheaters to know exactly what they’re up against. The marketing materials says it uses a “hybrid approach powered by driver code and machine learning.” A support document shows it looks for corrupted memory, unknown game files, untrusted system files, and debuggers, among other things. It also won’t run if operating system security features like driver signature verification and kernel patch protection are disabled, ex: If safe mode is enabled.

When is Easy Anti Cheat Active?

The EasyAntiCheat.exe process only runs alongside games that require it. if you’re not playing a game, EasyAntiCheat.exe isn’t running in the background.

When you launch a game that uses it— such as War Thunder, for example—EasyAntiCheat.exe starts up. It remains running while you’re playing the game, and shuts down when you close the game.

How does EAC Affect system performance?

Easy Anti Cheat will have minimum performance impacts depending on your hardware and equipment. Nothing that will affect gameplay.

Although EAC will act as a live scanner, the program will scan the game files asynchronous to prevent bog downs. Depending on your thread count this can be instant to a fourth a second. Nothing noticeable.

Where does EAC Install?

EAC will install into by default C:\program files\EasyAntiCheat on a windows machine and inside the game’s directory for linux and MacOs (unless changed by the distributor content provider).

The file size will take up no more than 50MB at best.

Q. Can we change the install location of EAC?
A. No, by default it will be hard installed to that file location and implanted into the windows registry.

Q. Can we manually move the files to a New drive?
A. In theory yes, you may move the EAC files to a new drive, such as moving it from your HDD to SSD, but this will require a registry edit, symbolic linking. There’s plenty of online resources from hundreds of players around the world explaining this.

Seems like they butchered EAC for Mac in some way, rendering us unable to play GRB specifically. ARB is fine, as I was playing my Mirage 2000 earlier

Yes, they did, but now it’s fixed. Just had 3 ground RBs without getting kicked.

i am facing dummy client error in war thunder ground realistic battles, please help

Hello, is the EAC Option checked in the launcher when you boot it up?

yes

What the…?
I was away for 2 weeks, then I updated the game and saw this:
Безымянный

see this it will help you

Uhh… Ok, It`s worked. But I didn’t understand what I did for this

Anti-Cheat doesn’t let me open the game because it says the file “bcryptprimitves.dll” is untrusted.
That file is made by microsoft themselves. Any explanations or ideas hot to fix?

Wait does this game have its own anti cheat program or it strictly only ban people who are being reported by other players? Im asking because I noticed, since this last ban wave, a surge of Chinese names with like 2k deaths and 40 kills then they have like 1400 kills and 5 deaths in premium planes, then they are in ofc all chinese squadrons…

easy anti cheat for my windows 11 won’t work

EAC isn’t working on my macOS-machine after the last update… Again! Do you guys really do some testing or you just don’t care and release cheaply programmed stuff?

Seeing how the folders are dated from 2019 yeah eac is not updated in a while.
