I found this really interesting. It's an OS that's really designed
differently! I love *nix but am always wondering "what if?"

Fuchsia is a general-purpose open-source operating system created by
Google. It is based on the Zircon microkernel written in C++ and is
currently under active development. The developers say that Fuchsia is
designed with a focus on security, updatability, and performance. As a
Linux kernel hacker, I decided to take a look at Fuchsia OS and assess
it from the attacker's point of view. This article describes my
experiments.
Summary
In the beginning of the article, I will give an overview of the Fuchsia operating system and its security architecture.
Then I'll show how to build Fuchsia from the source code and create a
simple application to run on it.
A closer look at the Zircon microkernel: I'll describe the workflow of
the Zircon kernel development and show how to debug it using GDB and
QEMU.
My exploit development experiments for the Zircon microkernel:
Fuzzing attempts,
Exploiting a memory corruption for a C++ object,
Kernel control-flow hijacking,
Planting a rootkit into Fuchsia OS.
Finally, the exploit demo.
