This is the story of how I found one of my favorite iOS vulnerabilities so far. It’s one of my favorites because of how simple it was to implement an exploit for it. There’s also the fact that it uses a legacy public API that’s still relied upon by many components of Apple’s operating systems, and that many developers have never heard of.

However, just as any process on the system can register to receive Darwin notifications, the same is true for sending them. Considering these properties, I began to wonder if there were places on iOS using Darwin notifications for powerful operations that could potentially be exploited as a denial-of-service attack from within a sandboxed app.
