XPC Exploitation series Learn XPC exploitation - Part 1: Broken cryptography Learn XPC exploitation - Part 2: Say no to the PID! Learn XPC exploitation - Part 3: Code injections Intro The last technique I showed in my presentation during Objective by the Sea v3 conference was abusing privileged XPC services using different code injections. In many apps I exploited, I observed that developers are aware that privileged XPC services have to verify incoming connections.

XPC Exploitation series Learn XPC exploitation - Part 1: Broken cryptography Learn XPC exploitation - Part 2: Say no to the PID! Learn XPC exploitation - Part 3: Code injections Intro Hey! In my last post, I showed you how weak SecRequirement string might lead to incoming connections validation issues. This post will focus on another way to trick XPC servers into trusting our malicious process. 😈 We’re going to exploit a vulnerability that I found some time ago in Malwarebytes.

XPC Exploitation series Learn XPC exploitation - Part 1: Broken cryptography Learn XPC exploitation - Part 2: Say no to the PID! Learn XPC exploitation - Part 3: Code injections After my talk on Objective by the Sea v3 I received a lot of questions regarding XPC exploitation. I think summing it up in a blog post series is a good idea, so here you have the first one! A post covering how to secure XPC services is planned in the nearest future.
