This repository contains the source files for the 6.72 version of Sleirsgovey's ps4jb2/672/src repository. The intention of this repository is to allow me to make my own changes, modifications, attempted improvements, etc. Essentially, it serves as a custom fork of the original repository, which I will maintain.
The netcat.c file loads 65536 bytes at the address stored in the JS variable mira_blob into RWX memory and jumps to it. At this point, only the minimal patches (amd64_syscall, mmap, mprotect, kexec) are applied, which means the process is still "sandboxed." Normally, mira_blob contains MiraLoader.
In the background, mira_blob_2_len bytes at mira_blob_2 are sent to 127.0.0.1:9021 in a separate thread. If mira_blob contains MiraLoader, it will run in the same way but with the full patch set applied and the device already jailbroken.
