Apple’s Sandboxing (“SeatBelt”) has remained terra incognita since Dionysus Balazakis’s seminal work. 5 years and 300 versions later, however, much as changed. The sandbox has become the linchpin of security in iOS, and the foundation of SIP in OS X 10.11 and later. This talk explores the sandbox in detail, and fills in the gaps from the original work. In particular, we explore the implementations on *OS and OS X, and how they differ. This includes: – Voluntary vs. non-voluntary confinement – Sandbox profiles, both in scheme syntax and binary form – The MACF syscalls hook, primarily ms_sandbox() APIs – Sandboxd (OS X) – ContainerManager (iOS) – Entitlements – Interaction with AMFI All gleaned from reverse engineering, the techniques of which will be of course demonstrated alongside. === CTO of Technologeeks.com, and has been a trainer and consultant in the operating system space for more than 15 years.
