While Apple has confirmed that recently leaked iOS 9 iBoot source is authentic, the company has dispelled any concerns users may have about the leak compromising iPhone security.

In a statement to MacRumors, Apple emphasized that the leak is for iOS 9, a three-year-old operating system that is installed on less than seven percent of devices, and notes that “by design the security of our products doesn’t depend on the secrecy of our source code” and “There are many layers of hardware and software protections built into our products.”
Although Apple also sent a DMCA takedown notice to GitHub this morning to get the code removed from the site, it’s also worth noting that the leaked code was incomplete, preventing it from being compiled, but providing enough data to allow security researches an inside look at the code that could make it easier to find vulnerabilities and create new jailbreaks.
However, Apple and other security researchers have emphasized that the company doesn’t rely on “security by obscurity” tactics such as source code secrecy, and therefore should be of any concern to average users, even those who are still using iOS 9.
