PS5 Jailbreak News: 7.61 Umtx Progress, Hypervisor exploit details and more!

Summary

In this PS5 jailbreak update, significant progress has been made with Flats successfully chaining the bdj userland and MTX kernel exploits for firmware 7.61. Although the exploit takes about 20 seconds to load and has some stability issues, it shows promise. Hammer 83 has introduced new jar loader versions for testing across firmwares, and the logging process has been improved for easier data capture. Community involvement is encouraged to enhance compatibility, while upcoming talks could reveal new hypervisor exploits. Overall, the scene is evolving with promising developments on the horizon.

Takeaways

• 🔍 Significant PS5 jailbreak news updates have emerged, particularly from a hacker named Flats.
• 🛠️ Flats has successfully implemented a jailbreak for PS5 firmware 7.61 using the BDJ userland and MTX kernel exploits.
• ⏱️ The jailbreak currently takes about 20 seconds to load, and Flats aims to reduce this loading time before public release.
• 🔒 There are no major kernel panics reported, indicating a stable exploit, although there is a potential deadlock issue to address.
• 💻 Hammer 83 released two new jar loader versions for running the MTX jailbreak, enabling testing across different PS5 firmware versions.
• ⚙️ Version 2 of the MTX exploit ran successfully on firmware 4.03, while both versions crashed during tests on firmware 7.61.
• 📊 Improvements in logging allow users to capture logs from existing ISOs without needing to compile their own, facilitating easier testing.
• 📈 Hammer 83 is seeking logs from users in the research and development Discord to enhance exploit compatibility across firmware versions.
• 🤔 There is ongoing uncertainty about integrating Flats' hypervisor exploit into the current jailbreak release due to dependency on another developer's public information.
• 🗓️ Spectre's talk on October 24 will cover hypervisor exploits, with potential releases of scripts for reverse engineering shortly after.

Q & A

What significant development regarding PS5 jailbreak was mentioned in the update?

Flats revealed a working implementation of a PS5 jailbreak using the Blu-ray drive up to firmware 7.61, combining the bdj userland exploit and the MTX kernel exploit.

Why hasn't the PS5 jailbreak been publicly released yet?

The jailbreak is not yet released because it takes approximately 20 seconds to load, and Flats aims to reduce this time and solve an issue where the system can get deadlocked.

What are the two new versions of the jar loader mentioned in the update?

The two new versions are mtx1 snapshot.jar, which uses Flats' looping method, and mtx2, which employs a different looping method called chabar or chabur.

What improvements were made regarding logging the exploit?

The logging process was improved so that users no longer need to compile their own ISO. They can now use the existing ISO and select their computer's IP address through a menu to capture logs.

What confusion exists regarding Flats' version of the bdj exploit?

Some users are uncertain whether Flats will integrate his hypervisor exploit into the bdj and MTX kernel exploit chain, as the hypervisor exploit is currently not implemented and is waiting for information from another developer.

What is the status of the hypervisor defeat methods mentioned in the update?

There are three current hypervisor defeat methods, with the first being presented at an upcoming conference. The second is in private by Flats, and the third appears to be mitigated in higher firmware versions.

When is Spectre's talk about hypervisor exploits scheduled?

Spectre's talk is scheduled for October 24th in the Netherlands, although it typically won't be live-streamed and will be posted on YouTube a week or two later.

What is expected to be released following Spectre's presentation?

Scripts to assist in reverse engineering the system will be made publicly available after the presentation.

What did the presenter learn from testing the jar loader versions on different firmwares?

The presenter tested mtx1 and mtx2 on firmwares 4.03 and 7.61, noting that mtx2 ran successfully to completion on 4.03, but both versions crashed during testing on 7.61.

How can users contribute to the development of the PS5 jailbreak?

Users in the research and development Discord can post logs of the exploit running on different firmwares, which will help improve compatibility and stability.
