Explore an advanced exploit technique called Data-Oriented Programming (DOP) for privilege escalation in MacOS. Delve into the complexities of kernel exploitation using DOP, which requires three key primitives: information leakage, arbitrary address read, and arbitrary address write. Learn how DOP offers advantages over Return-Oriented Programming (ROP) by maintaining exploit effectiveness despite kernel code changes. Examine a real-world example of transforming a single heap buffer overflow vulnerability into a full privilege escalation attack using DOP techniques. Gain insights into the strengths and challenges of implementing DOP in practical scenarios, and understand its potential impact on MacOS security.
