Well, apparently hacking MMOs with cheat engine to increase your 'stats', 'money' etc. is quite complicated, I am a complete noob about this stuff (the packet manipulation stuff), Is it possible to change the real data because I heard the real data is connected to the servers of the company running the MMO (eg- WOW, Wizard 101, LOL). So is it possible that you can change the data in the servers by manipulating packets? Is cheat engine capable of doing such things (cause I'm not completely thorough with cheat engine) or do you need any other software?

Thank you for your reply in advance. Very Happy

You can use cheat engine to change packets, but they are not a magical thing as some people claim
A packet is just a message.
Now if you go to the bank and tell them you have 2 million on your account and wish to withdraw it they probably won't do it, because they first check if you actually have 2 million on your account.
The same goes for servers. You could say "take 500000 gold from chest" while the chest only contains 2 gold, it will fail because the server knows it only has 2 gold.
Of course, some games are designed by completely incompetent programmers, and in those you may be able to do that. So just try (expect to be instantly banned if it doesn't work)

In 99.9% of the newer MMOs out today, you wont be able to hack things like your stats (HP, MP, Strength, Agility, etc.) as they are all handled server sided.

There are other things that sometimes land up being unsynced from the server/client because it is too much on the server to handle. Stuff such as your characters position (x,y,z), movement speed, and such. All in all it depends on the MMO itself, each have their code different than another, so you may be able to hack your stats on one, but not another.

For example, putting a popular MMO into perspective, World of Warcraft; you can:
- Edit / alter your characters position X/Y/Z
- Edit / alter your characters speed.
- Edit / alter your characters animation state, (swim anywhere etc.)

And so on. Just think outside of the box when you start looking for things.

How about to save the sent packet when you do some thing that gives you some gold and resend it to server manually to get extra gold?
is that possible easy like this ?

The problem is that there tends to be protection that keeps values on the server and does sanity checking on the incoming data from the client. Of course some games have worse protections and there can be ways to do what you want.

Start by analyzing what traffic is sent by the game in question. And most likely the traffic will be encrypted or obfuscated so it's not obvious what each packet actually conveys.

Depends on the game, in some cases, yes this will work.

But in a lot of cases most games mark items with a unique ID and have validation checks to ensure that you are not doing things like this. In some cases the packets will contain other unique things such as:
- Unique Item ID
- Base Item ID
- Inventory slot the item is in when being sold / altered.
- Time of sale / alteration.

These will prevent you from spamming the packet to get free money.

But, as said before this all depends on the game. You will have to test it and see if it works for your case. I do know that some games I have played and messed around with had similar things to this that did work and I was able to mass produce gold/currency in them.

In more modern, mainstream/triple A games though things like this are rare to find.
