A collective of hackers claims to have reached a significant PS5 milestone

Points Highlighted:

  • Finding the root keys can be one of the first steps in ‘jailbreaking’ a console, but fail0verflow’s discovery doesn’t mean the PS5 has been fully compromised yet.

  • “Translation — we acquired all (symmetric) PS5 root keys,” said a follow-up tweet. If you look hard enough, you can get them all from software, even the per-console root key.”

Symmetric root keys enable hackers to decrypt files, including firmware, meaning hackers can try to reverse-engineer it and look for exploits which can be used to run unsigned code on the the console.

In a separate incident, Sony hacker Andy Nguyen posted a tweet yesterday which appeared to show that he had been able to activate debug settings on a retail PS5.

The group also claims that it may not be particularly easy for Sony to reverse this with a system update. When another Twitter user asked if the root keys could be ‘rotated’ easily, the group simply replied: “No.”

However, he quickly shot down any hope that he would be sharing the process by tweeting: “No plans for disclosure. No ETA”.

Last week it was claimed that PlayStation 5 consoles reportedly no longer lose game playing functionality when their internal CMOS battery dies.

That’s according to a new analysis by Hikikomori Media, which appears to confirm that a PS5 with a missing or expired CMOS battery can now run physical and digital PS4 and PS5 games.

The only exception are games claimed via a PlayStation Plus subscription, which will no longer work with an expired or removed CMOS. Previously, tests suggested that PlayStation 5 consoles would retain some game playing functionality after their CMOS batteries died, but most physical PS5 discs and all digital games would no longer boot.
