The next two hundred pages some you are about to read provide detailed instructions that can be used to penetrate iOS and the software running on it. Many of the techniques demonstrated in this book explain vulnerabilities inherent to the basic design of the iOS operating system and the Objective-C runtime. They are intended for lawful, ethical penetration testing by developers to test and evaluate the security of the software they develop or audit. Neither the author, nor O’Reilly Media, nor anyone affiliated with this book condone or encourage the illegal use of these or any other techniques to commit criminal acts. These techniques were published in the interest of better equipping developers to design code that is more resistant to attack. The criminal community is already well aware of the inherent weaknesses of iOS applications. Withholding such information from ethical developers only serves to do more harm than good.
