Engadget Logo Engadget Japanese version hacker group announced that they have obtained the "root key" of PS5. Will your homebrew software work soon?

Successive PlayStation products have been strictly protected, and even the latest generation PS5 has not succeeded in "jailbreaking" such as installing self-made software. Meanwhile, a hacker group has announced that they have obtained the PS5 'root key'.

This announcement comes from hacker collective Fail0verflow. The group is known for running Linux on the Nintendo Switch as soon as possible.

Fail0verflow's tweet contains what appears to be an encrypted PS5 firmware, highlighting code that references a "secure loader". In other words, it seems that we have succeeded in analyzing the firmware and are one step closer to creating a custom firmware that can boot the PS5's homebrew software.

Whether you extract the PS5's system software or put in your own custom firmware, you'll need some sort of vulnerability to read or write to the PS5's heavily protected kernel. . Fail0verflow's post doesn't mention the specifics of the vulnerability, but states that the root key is "obtained from software", implying that no hardware modification is required.

Separately, well-known PlayStation hacker theFlow0 tweeted an image of "debug settings" in the PS5's settings list.

According to console hacking news site Wololo, this debug setting was previously only seen on development hardware, but the GUI is very different this time. He said.

In other words, Mr. TheFlow0's tweet probably used the share function of the general PS5. In other words, the debug settings are hidden in the commercially available PS5, and it is speculated that the vulnerability was used to enable an internal flag that cancels the hidden mode.

At the time of writing, TheFlow0 also added that the PS5 vulnerability "has no plans to be made public." In recent years, he has participated in the "PlayStation Bug Bounty" program, so rather than providing it to hackers, he may report it to Sony and fix the vulnerability quickly.
