Talk Title:

Exploiting XPC in AntiVirus Software

Abstract:

In this talk we will publish our research we conducted on 29 different AntiVirus products on macOS through 2020. Our focus was to assess the XPC services these products expose and if they presented any security vulnerabilities. We will talk about the typical issues, and demonstrate plenty of vulnerabilities, which typically led to full control of the given product or local privilege escalation on the system. At the end we will give advice to developers how to write secure XPC services.
