Open-source jailbreaking tool for older iOS devices

Here is a tweet by the developer with some explanations

> What I am releasing today is not a full jailbreak with Cydia, just an exploit. Researchers and developers can use it to dump SecureROM, decrypt keybags with AES engine, and demote the device to enable JTAG. You still need additional hardware and software to use JTAG.

> During iOS 12 betas in summer 2018, Apple patched a critical use-after-free vulnerability in iBoot USB code. This vulnerability can only be triggered over USB and requires physical access. It cannot be exploited remotely. I am sure many researchers have seen that patch.

How is this not drowning in attention here?
