For a very short time, on Thursday morning, the iBoot source code of iOS 9 was freely available at GitHub. A few hours later, Apple issued several DMCA notifications and "cleaned" repositories from GitHub.
But as most of us know, when something is published on the Internet, it is almost impossible to "collect" it. 
This probably also happened with iBoot, which is probably already on the computers of people who are interested in discovering valuables vulnerable points in Apple's source code.
Η Apple confirmed her leakage αλλά σύμφωνα με την εταιρεία λόγω της παλαιότητας του κώδικα αλλά και άλλων μέτρων ασφαλείας που χρησιμοποιεί η εταιρεία, η συγκεκριμένη διαρροή δεν αποτελεί πρόβλημα για την better safety of the devices.
Here is Apple's statement on CNET:
“The code appears to have been leaked three years ago, but by design the security of our products does not depend on the secrecy of the source code. There are many layers of hardware and software protected by our products and we always encourage customers to update to the latest software versions to take advantage of the latest features protections. ”
In other words, if you use a device running iOS 10 or later, you may not be at risk.
For those of you using an iOS device that can not upgrade over iOS 9, you probably need to think about an update on a newer device.
