PS5 JAR Loader Update: Version 4.1.1 Released
Developer Hammer-83 recently released PS5-JAR-Loader 4.1.1, a utility that allows users to run payloads via the bd-jb exploit on PS5 Firmwares up to 7.61. This latest version, 4.1.1, includes critical fixes for Firmwares 5.xx to 7.xx, following recent developments on these firmwares.
Understanding PS5 JAR Loader
According to the Readme file:
This project leverages vulnerabilities found in the BD-J layer of PS5 firmware versions 7.61 and earlier to deploy a loader capable of executing JAR files’ main class. This simplifies the process of burning the BD-R disc with the loader just once and subsequently running new versions of experimental code. The repository offers all the necessary setup instructions for creating both the loader BD-R disc filesystem and the JAR file to send to the PS5.
In essence, PS5 JAR Loader serves as a payload loader for the bd-jb exploit. Instead of creating a Blu Ray disc for each payload, users can burn a disc with PS5 JAR Loader, enabling it to load any payload sent via telnet. While the process may seem complex initially, numerous tutorials are available to guide users through the setup, making it relatively straightforward once familiar.
