The PS5 Hacking group is making sluggish however regular progress. While most of us should look forward to particulars on what SpecterDev talked about in his infosec presentation on the PS5 Hypervisor final week, there are nonetheless issues we will get our fingers on already. Developer John Tornblom has pushed a number of updates to his PS5 Payload SDK Implementation, including particularly arbitrary syscall help yesterday. Also, for the reason that final time we coated it, it appears the SDK has gained help for PIE (relocation help a.ok.a location impartial ELF recordsdata)
What is BD-JB for PS4/PS5
BD-JB is a sequence of exploits (an exploit chain) that enables exploitation of the PS4 and PS5, as much as firmwares 9.04 and 4.51 respectively, revealed by Hacker TheFloW in 2022. The hacking scene has been creating and sustaining a sequence of instruments counting on these vulnerabilities, particularly to load and execute unsinged code (binary payloads and/or ELF recordsdata) on the PS5.
Because it depends on vulnerabilities within the Blu-Ray layer of Sony’s consoles, within the case of the PS5, this exploit isn’t appropriate with digital version PS5s. Those working a Digital Edition of the PS5 may need to strive the Webkit exploit, which is appropriate as much as firmware 4.51 included.
What’s the PS5 Payload SDK
From the Readme:
This is an SDK for growing ELF payloads focused at exploited PS5s working the BD-J ELF loader. Several artifacts on this repository originate from the PS5SDK undertaking.
