Full Video of Apple Engineer's Black Hat Security Talk Now Available

Earlier this month, Apple's head of security engineering Ivan Krstic gave a talk at the Black Hat Conference, an annual event designed for the global InfoSec community. During the event, Krstic spoke about Apple security and unveiled the company's new bug bounty program.

Krstic's briefing is now available in full on YouTube, shared this morning on the Black Hat YouTube channel in a video entitled "Behind the Scenes of iOS Security."


In the talk, Krstic covers three major iOS security mechanisms -- HomeKit, Auto Unlock, and iCloud Keychain -- in "unprecedented technical detail," along with other iOS security measures.

HomeKit, Auto Unlock and iCloud Keychain are three Apple technologies that handle exceptionally sensitive user data - controlling devices (including locks) in the user's home, the ability to unlock a user's Mac from an Apple Watch, and the user's passwords and credit card information, respectively. We will discuss the cryptographic design and implementation of our novel secure synchronization fabric which moves confidential data between devices without exposing it to Apple, while affording the user the ability to recover data in case of device loss.

Data Protection is the cryptographic system protecting user data on all iOS devices. We will discuss the Secure Enclave Processor present in iPhone 5S and later devices and explain how it enabled a new approach to Data Protection key derivation and brute force rate limiting within a small TCB, making no intermediate or derived keys available to the normal Application Processor.

Traditional browser-based vulnerabilities are becoming harder to exploit due to increasingly sophisticated mitigation techniques. We will discuss a unique JIT hardening mechanism in iOS 10 that makes the iOS Safari JIT a more difficult target.

The most notable moment of Krstic's briefing features the unveiling of Apple's first ever bug bounty program, which will see the company paying out up to $200,000 to researchers who discover vulnerabilities in Apple software. Apple's bug bounty program, initially limited to a few dozen researchers, launches this September.

I don't understand most of it either, but it's pretty fun to see how serious Apple is about system security.

I'm currently doing network administration, where network security is one of the topics we learn about. May not be on a big scale, but I actually like this whole subject. And I'm planning on doing something with security engineering after this.

So I may not understand 99% of this, it's just fun to watch. :p

Sure, compared to whom?

And who takes security+privacy as seriously?

Who has an executive team that can axe marketable features for privacy reasons, that not even 1% of people gives a damn?
Calm down dude. It was just a sarcastic joke in response to another quote.

Apple's password to unlock everything is 12345. Try it out!
I've got that same combination on my luggage!

RIP Jailbreak.
If the choice is between security that vexes even governments, and wacky add-ons, I'll take the security every day and twice on Sunday.
