Is this easily hackable?

You know what the chanches of finding the right memory address on a ue4 exe for a single boolean are?

Also, unless the variable is exposed or linked in some way, the memory address for it should be randomly defined any time you reaload the exe.

Network sniffing wise, that’s a little different.
Maybe you could find a single variable value to send to the server.
And if you could, maybe you could append that to every request.
The answer there is simple though. Ban anyone thats blocking constantly.
