PS4 Shown running Linux at Tencent Security conference in China (video)
The infamous Chaitin PS4 Jailbreak was showcased once again, this time at Tencent Security conference in China. A video of the exploit was shared by security research Noam Rathaus from the event.
Although the video does not give details on the firmware this is running on, it is likely running on PS4 4.01, the same firmware this was running on when it was initially revealed almost a year ago.
As a reminder, the team behind the exploit has disclosed it to Sony last year, and the exploit was patched with PS4 Firmware 4.06.
Chaitin tech also allegedly signed a non disclosure agreement with Sony regarding that FreeBSD Kernel exploit, and have never revealed the details of the kernel exploit.
They have however spoken in the past about some of the vulnerabilities involved in the jailbreak. For example the Webkit exploit used as an entry point was apparently based on the webkit exploit used in PS Vita’s Henkaku. Chaitin Tech members named the port of that webkit exploit “FireKAKU”, as revealed on reboot.ms.
However, even if they’ve described some of the components of the hack, the critical bit, the kernel exploit, was never publicly revealed (except for a CVE that might have been connected to the hack), and there is no reason to believe they will ever reveal it. Some scene hackers have also been sitting on that patched exploit for a while now, which is a bit hard to understand.
In other words, there’s nothing new here for the scene: the same old exploit is being showcased in multiple Infosec conventions, a year after it was already revealed, for some reason. In parallel, there hasn’t been any word of a release from hacker qwertyoruiop who claims to have an exploit running up to at least firmware 4.55, and the only rumors of incoming PS4 jailbreaks so far haven’t led to anything concrete.
