At first, Apple products were tall, wide, and attractive to cyber attacks. The average hacker found the company's proprietary software nearly impossible to crack, and the attack surface of an Apple product was almost nonexistent. But over the years, those attack surfaces became larger, and the hackers and their tools became more sophisticated. A big target for hackers has always been the iPhone because most users live their lives on that small, useful device, and most keep their confidential data stored on their Apple-branded hardware.
These days, everything is hackable, and each of us has a responsibility to take the appropriate steps to protect ourselves. Gone are the days when the default settings were good enough. (Actually, researchers would argue that the default settings were never good enough.)
