Aeria does not have a storage of AP as such... its a virtual currency. To hack it you would have to do some sort of sql injection or maybe remote desktop or admin console which are all probably pretty secured against and because its to do with something money buys kinda illegal
If you really wanna try find out if they use any exploitable php on their website but im sure many have already tried.
If you can get a shell uploaded then your good to go but good luck getting that far lmao.
