Function hacking/editing In Java coded game [Possible?]

Post by ronokae »

Okay here is my overview:
I've been studying Screwing around with packet editing a lot lately on poorly protected online Java games.
overall I understand how you can hack something, by editing hex values/resending packets etc.
However I wanted to know something:

Say there is a Java-Based game like "Maple Story" (which isn't coded in java i don't think but just using as an example)
So in the game,
say you open a magical box, and after you open it you get 20 coins.
In many of the MMORPGS and such I've hacked with packet editing so far, I could normally
just repeatedly send that packet and I'll be just fine.
however I want to know if it's possible to change function that is done upon sending/recieving a packet

lets say the function is

if (BOx_is_ opened)
{
Take_box_from_slot then
Replace_With_this_(20gp)
}

now i know that that is barely java, let alone any coding at all, but thats just the basic idea of what i mean.
I want to know if its possible to change it such as:

if (box_is_opened)
{
Take_box_from_slot then
Replace_With_this_(whatever item i want)
}

Any feedback would be highly appreciated.

i dont really see this being game hacking, but its been discussed many times. its basic game hacking.
it doesnt matter where you change that 20. if there is a server sided check, it wont matter if you change 20 to 2000 in client file, memory or in packet, result will always be same, that it never changes if there is online check.

~"School is for idiots"~

Has it really? I apologized should have searched more.
Thank you though.

Server check = Check Sum no?


So what you're saying is that this would require me hacking into the server it's self rather than
just editing some things on my part correct?
If that's the case what would be a wise alternative to look up?

read MMO hacking. you have to decide what you looking for before making a topic.
its getting from java game hacking into something completely different
