PS5 kexploit: Prosper0gdb (debugger) update + SELF dumper by Sleirsgoevy, Blocker update by 68Logic

There have been some good releases for PS5 in the last 24 hours. Slersjovi He updated his BD-JB implementation for PS5, improving boom0gdb (debugger) support, as well as adding an overhead for unloading system files. There is a lot to do, including decrypted and shared system files (download links at the end of the article). Let’s dig!

What is propser0gdb for PS5?

Propsero was Sony’s internal codename for the PS5 (and/or SDK). The name (or, in this case, stylized as “Prosper0”) has been used by various developer hackers to identify the specific PS5 gadgets and codes they created for it.

Propser0gdb is a Sleirsgoevy debugging tool for PS5 jailbreak. It was added to its bd-jb app in early October 2022.

PS5 BD-JB Exploit – What’s new in this version

Sleirsgoevy has added a memory mapper (mmap) function to his toolkit, which allows us to access files in memory, and then dump those files (using the built-in SELF dumper utility).

At a quick glance, there seem to be more files than there were It was already inundated several months ago by a webkit exploit.

Since some of the content has been fully decrypted, the people at the scene have looked at the files in debuggers for consideration, such as the PS4 developer OSM:

OSM has advertiser Some devkit related code is still in the retail libraries. This can help hackers search further.

I suppose similar tools could easily be created to exploit Webkit as well, maybe it’s just one of the hackers working on the webkit version to port it.

Blocker update by 68Logic

In an unrelated version, 68Logic contains Unleash a dwarf payload To exploit the webkit, which blocks firmware updates. This works by creating a folder where the temporary update file should normally be downloaded by the console. Since the console cannot overwrite the folder, it does not download the update.

Although this payload represents great progress, the player It was mentioned that Sony knows about the trick and is now deleting these folders before trying to download, it is unclear if it actually works as expected. We advise people not to rely too much on this for now and instead Setting their exploitation environment in order to block the correct IP addresses.

As a reminder, to run some of these tools, you’ll need a file PS5 hackable.
