why are they un-hackable is it cuz they haz server stuff and its based on server things ?

It's not that they arent unhackable it's usually highly illegal and can even get you jail time. Plus it would probably take quite a while to develop something useful. Props to people who can. Honestly probably not very helpul sorry ;(
 

Why do you guys say '' you might be jailed'' ? 

what if i used a VPN, they will never identify me

also what if their  servers is based on USA for example and i hacked their servers while i live in inda for example, they won't travel from their country to my house just because i hacked some ingame money that costs less than 100$ right?

the only thing they would do that they will ban me and that is it, why taking it to serious? im not hacking the FBI or CIA or NASA , im just hacking some stuff in a stupid game...

And that only will happen if i got detected

Well there are ways, BUT if you hack currency you're basically commiting a crime.

Well, in my opinion. The reason is simply because most MMO's store their files in their server. Therefore we cannot really do anything to change those.

It is because they require you to hack into another person's secured server.  That server is secure and the person who owns it is required to follow Federal and International laws regarding server security.  They would not just detect the hacker, but also give them a direct ID on where the hack came from.  This in turn would be given to the police, who would come arrest our friend.  Hacking is a crime, and it doesn't work anything like you see in the movies.  The people who run these MMOs have financial information stored on the server, therefore any breach of that security is a federal offense.  It does not matter if our friend stayed completely away from the financial information and personal identifying data (your personal information), the fact is they would have access to it and that is enough to put them in prison for the attempt.  Any breach will be investigated.

The hacks that we are provided here are not a crime because all the information is on our own systems, and the Ultra Trainer does not create backdoor into our systems because our friends at KongHack aren't interested in illegal activities.  They are providing a service and we are consuming that service.  Code injection of the sort we enjoy here is a matter of "At-Your-Own-Risk".  The only one you can hurt by using it is yourself, and the fine folks at KongHack aren't interested in hurting their clients with malicious code.  They're good people.

The steps the hacker would have to take to hack a server would be:
1) Plant a trojan horse program on the remote server through either direct access (frequently impossible) or social engineering (phishing)
2) Execute that program to give them access to the server so they can make changes on it
3) Grant themselves administrator privilege on the remote server by escalating permissions
4) Find the correct database that holds the relevant information for the program in question
5) Provide injection values to alter the relevant information for the client to change their values
6) Maintain this access and permissions through the entire software lifecycle, which includes updating access for each and every patch

In short, hacking an MMO is something you'd only ever do if you both had nothing better to do and were willing to risk your freedom for practically no reward.  That level of risk would only be worthy if the financial gain promises to outweigh all the bad things that can and most likely will happen.  Never ask someone to do it unless you're willing to pay a few million in cash up front, plus bail and bond if they get caught.  If you've got that much dough to burn, you're better off just paying the MMO people for special favors, and not trying to put someone else in danger by having them commit a federal crime.

That's why most MMO games are unhackable.  On top of being very difficult with an almost guaranteed rate of failure, it's not worth the effort.  Some of these servers would also require some very specialized equipment which is not only expensive, but also very illegal to own without special permission from the government.  People who get hacked do it to themselves 99% of the time.  Servers get hacked because someone was dumb enough to let the hacker get the access they needed, not because they magicked their way into the data.

Agreed ..... If memory serves correct there was a torrentffreak article on FBI/interpol capturing a stalker in mid 2017 who kept on harassing defaming and framing the victim with questionable activities of *coughcough*adultindustry *coughaaaachuu* until was caught just by the logging timestamp information of a china VPN he was a customer of, who despite in their advertising and claiming of not logging any kind of information willfully cooperated with the international authorities and handed them their customer logging timestamp infomarion so the target criminal could be apprehended . Its old news by now but with regards to VPN it was an important piece of news and besides the point stand in this current age where the e-commerce industry is as relevant as your local food market / seven eleven or local grocery shop where you purchase your daily food supply from. Then there is no arguing that VPNs are just virtual browsing conveniences only and privacy within any digital product that has access to the internet is as much valid as net neutrality, take this statement as a pun or seriously IMO its self sufficient and provides a concrete closure  the subject.
