Due to Arma II now using Kernel module these days you're not able to inject hacks without an injector that does Kernel. Xenos is one that does it, but it's driver signature is not valid and you need to run it in Driver test signing mode that earlier got you banned in Arma II, but now it won't even launch if you have it turned on. You need to find a private one from someone...
Please see my 'Current State of DayZ Hacking' Thread linked in my signature if you want to know more (Some of the info might be semi-outdated!).
