They may be hugely popular with developers and universally hated by users, but there is little doubt that the in-app purchase model is here to stay. With no sign of going away just yet, especially in the gaming arena on mobile devices, in-app purchases are often used to give developers a long running revenue stream by getting users to buy in-game currency and other consumables using real money. Unfortunately, a new report claims that the world of in-app purchase is far from secure.

Back in June of this year, it came to light that a small bunch of security researchers had managed to find a way of injecting unwanted code into iOS devices by using a malicious USB charger. That revelation may have caused concern to a lot of users, but it seems that the latest beta of iOS 7 has resolved the security flaw, as promised by Apple in a recent statement.
