An attacker removes or modifies the logic on a client associated with
						monetary calculations resulting in incorrect information being sent to the
						server. A server may rely on a client to correctly compute monetary
						information. For example, a server might supply a price for an item and then
						rely on the client to correctly compute the total cost of a purchase given
						the number of items the user is buying. If the attacker can remove or modify
						the logic that controls these calculations, they can return incorrect values
						to the server. The attacker can use this to make purchases for a fraction of
						the legitimate cost or otherwise avoid correct billing for
						activities.
