This blog post dives into the most common classes of macOS Local Privilege Escalation vulnerabilities, from insecure XPC communications and time-of-check to time-of-use (TOCTOU) Race Conditions to a range of implementation and configuration oversights. We will explore how attackers can exploit these weaknesses to escalate privileges, and highlight real-world examples to illustrate recurring patterns. This post ends the series on Intego products on macOS by revealing vulnerabilities that can lead to Local Privilege Escalation, as well as a surprise bonus.

This is the second of two blog posts about macOS kernel debugging. In the previous post, we defined most of the terminology used in both articles, described how kernel debugging is implemented for the macOS kernel and discussed the limitations of the available tools; here, we present LLDBagility, our solution for an easier and more functional macOS debugging experience.

This is the first of two blog posts about macOS kernel debugging. Here, we introduce what kernel debugging is, explain how it is implemented for the macOS kernel and discuss the limitations that come with it; in the second post, we will present our solution for a better macOS debugging experience.
