Blocking Scripted Remote Execution

Categories: ArmA 2, ArmA 3

Recently, there have been a lot of server file leaks. The way cheaters obtain server files has always been the same. Remote Execute some code up to the server that retrieves data and returns it back to the cheater’s client. Upon receiving data the cheater writes it to their log file or profilenamespace or something […]
