View Full Version : Exploit/bug with Graal 2001

As the NPC server was down one time, I noticed that my rope still worked, as did all of my other NPC weapons.

No other NPCs worked but the NPC weapons. Night/day was intact because, well, it's in an NPC Weapon. Rather, an invisible one.

Stefan, I have a couple of suggestions to fix this. Find a way to encrypt the text in memory, or have NPC weapons server-side as well...

Just a thought.

that would be hard to do

an MD5 hash with some random character key (so a memory editor won't be able to distinguish the random characters from other stuff)

actually, ya know.. now that I think about it. I don't know if it really can be done. It all depends on how the script is parsed and how often it's done.

Problem is to protect the compiled npc script in memory.
Everything can be hacked if you look at the Graal.exe program
(assembler code).

But it's now possible to have server-side script for
the npc weapon, it can be put in the server-side control-npc.
That is also used for the new 'Trading item' which uses
the server-side script command putnpc2

The aim is to have everything graphical client-side,
while having everything secure stuff server-side.

Wouldn't server-side NPC weapons be really 'slow' like bomy pets or other npcs?

Hmm, everything is going like this...hmm...
