Kexploit PS5: Update Prosper0gdb (debugger) + SELF dumper by Sleirsgoevy, Update Blocker by 68Logic

0

A few good releases for PS5 have happened over the last 24 hours. Sleirsgoevy updated its BD-JB implementation for PS5, improving prosper0gdb (debugger) support, as well as adding a payload for dumping system files. There’s a lot to browse, including decrypted system files that have been shared (download links at the end of the article). Let’s dig!

What is propser0gdb for PS5?

Propsero was Sony’s internal code name for the PS5 (and/or its SDK). The name (or, in this case, stylized as “Prosper0”) has been used by several hacker developers to identify the PS5-specific tools and code they’ve created for it.

Propser0gdb is Sleirsgoevy’s debug tool for the PS5 Jailbreak. It was added to its bd-jb implementation in early October 2022.

PS5 BD-JB Exploit – What’s New With This Version

Sleirsgoevy has added memory card (mmap) functionality to its toolset, which allows us to access files in memory, to then dump those files (with the included SELF dumper utility).

Zecoxao shared a series of files dumped via this code:

At a quick glance there seems to be more files than what was already dropped several months ago via the webkit exploit.

Since some of the content is fully decrypted, the folks there went through the files in the debuggers to look at them, like the PS4 developer MSO:

The OSM has declared some code related to the devkit still exists in retail libraries. This could help hackers continue their research.

I guess similar tools could be easily created for the webkit exploit as well, maybe this is just one of the hackers working on the webkit version to port them.

Update Blocker by 68Logic

In an independent version, 68Logic has released an elf payload for the webkit exploit, which blocks firmware updates. It 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 is a nice step forward, Al Azif mentioned that Sony knows the trick and now deletes these folders before attempting the download, it’s unclear if this really works as expected. We advise people not to rely too much on this at this time and instead configure their operating environment to block good IPs.

As a reminder, to run some of these tools you will need a Hackable PS5.
