Hey guys, so this is my first time actually attempting to hack a game besides using other people's softwares and stuff. I have always been interested in creating my own hacks and intend to go into cyber security as a masters. But basically I am trying to hack this iPhone game called Puzzles and Dragons aka PAD. I know this game is hackable because a Japanese student had hacked it but got arrested a year or two later. So basically this game has binary files that store monster's and there damage,hp, etc. and that is what he used to hack/modify. I opened the data files in ida however all I get in the function window is 'sub_'x ... I also tried to find the offsets of a monster but that seems impossible. Any advice on where to look would be greatly appreciated. I would love a mentor or even just a tip towards the right direction. Btw I also have a few versions of the exe he released to modify the game bins in the past (anyway to look through those exe's in order to figure out what he did to modify the bins?) Thanks again everyone!
