Now, though, there's an answer: Corellium. The software can spin up virtual iPhones and iPads, amongst other Apple systems, all running the latest iOS operating system. From there, hackers and software developers can try whatever they want on the device, whether that's looking for security weaknesses or just testing their apps on different Apple hardware and software. It's possible to pause, rewind and fast-forward everything that's done on the device too, whilst Corellium reveals the internal code to help hackers discover what went wrong (or right) when they started tinkering. It won't matter if the software crashes; you can just create a new virtual Apple device in 10 minutes.

He was most impressed by the ability to hunt for bugs in the kernel (the deepest level of an operating system from which all other software are launched) of the latest iOS version without the need for a real device.
