I think this is HOW COMEDOR CHEAT
"Freemium Isn't Free". If you did play with freemium games, you definitely have to watch it There are many problems with freemium games. It is free to install, free to play. The first 3-4 hour might be fun to play. But after that, it turns out it is impossible to advance in the game without paying money for it. And by paying money, I mean paying a LOT!
xor eax, 0baadf00d
rol eax, 0e
What does it mean? The actual credit is encrypted in memory. If you want to scan it in memory, you won't be able to find it. But! The encryption is rotating the value to the right (ROR) with 0xE (14 in decimal), and after that it is XOR-ed with 0xbaadf00d . Decrypting it is the inverse of the functions in reverse order (in this particular case, the order does not matter, but that's not the point). The inverse function of XOR is XOR, and the inverse function of ROR (rotate right) is ROL (rotate left). Now that we analysed the assembly code, we can be sure that it is safe to execute and see your coins falling from the sky. For free. In a freemium game. Have fun!
Another interesting thing is that I don't recall any thick client applications in the financial industry encrypting the values in memory. And I agree, there are bigger problems with thick client applications than not encrypting the important values in memory. But still, some thick client applications are constantly updated, maintained. Maybe it is a good idea to encrypt the values in memory. It will make attackers life harder. Not impossible, but harder. Maybe the developers of these applications should learn from the gaming industry (or from malware developers for that matter), because it is a shame that an 3D combat strategy game or an FPS is protected better than an application responsible for transacting millions of dollars. Just think about the RAM scraping malware stealing millions of credit card data ...
Morale of the story
Cheating is part of the gaming history and the freemium games are trying to take away the cheats from the gamers, because they WANT MONEY. Thanks to CheatEngine and some clever hacks, these programs can be still beated. And guess what, there is CheatEngine for Android too.
So activision do your job and ban cheaters. Make the game little easier for colecting resurses so we dont have to cheat if we dont have $ to pay
