PS5 Release: PS5 JAR Loader 4.1.1
PS5 Developer Hammer-83 released PS5-JAR-Loader 4.1.1. The utility lets you run payloads via the bd-jb exploit, on PS5 Firmwares up to 7.61 included. Version 4.1.1 in particular fixes some critical offsets for Firmwares 5.xx to 7.xx, following recent advances on these firmwares.
What is PS5 JAR Loader
From the Readme:
This project uses vulnerabilities discovered in BD-J layer of PS5 firmware version 7.61 and earlier to deploy a loader that is able to listen to JAR files and execute their main class. This makes it easy to burn the BD-R disc with the loader just once and then keep on running new versions of the experimental code. This repository provides all the necessary setup needed to create both the loader BD-R disc filesystem and the JAR to send to the PS5.
In other words, PS5 JAR Loader is a payload loader for the bd-jb exploit. Instead of having to burn a Blu Ray disc for every single payload you want to load, you just need to burn a disc with PS5 JAR Loader, which in return will load any payload you send to it via telnet. It might sound complicated, but there are tons of tutorials around on how to run it, and once you’re used to it it’s fairly straightforward.
