a simple frida-based fuzzer for skylight(WindowServer) based on @ret2systems pwn2own work https://blog.ret2.io/2018/07/25/pwn2own-2018-safari-sandbox/
A reproduction of ret2's skylight fuzzer for MacOS Mojave.
To use it, just run sudo node driver.js
You can generate window traffic to be fuzzed however you wish, however I have included a file wintraffic.js to get you started.
