If it is a noob protection then you could have done this by yourself, don't you?
A brief explanation on what depmax64 do would suit on your need of information here. Depmax64 is a tool for server admins that run l2off servers that injects itself into the server and performs some validations to prevent the most common exploits. It is just a double check that you (the client) are sending (some) correct information to the server. There is no way you can bypass it since you are not allowed to manipulate the server itself (otherwise I would just update my char in the database :) ). What (possibly russian) people CAN do is find another hole that it is not patched already and exploit that, until a new version of depmax64 is released with a new patch. I hope this will be more clear to you.
