A new report reveals that a crucial ROM key for the Sony PS5 is now publicly accessible. This key is embedded within the BootROM code, which is the initial software that executes when the console powers on, serving to verify the authenticity of the boot file before the system fully loads.
This key, permanently stored in the main chip, cannot be altered through system updates, distinguishing it from previous vulnerabilities that were patched. Although possessing the key does not enable users to run unauthorized code immediately, it provides insights into the boot process, potentially facilitating further exploration of the console's operation from startup to the home interface.
All existing PS5 units contain this old key, meaning they aren't immediately at risk of running counterfeit software, as multiple security layers still protect the system. However, the weakening of one significant security measure may simplify efforts to investigate alternative methods, echoing past issues with the PS3 and Switch that allowed for similar exploits over time.
While this leak indicates a potential long-term vulnerability for the PS5, it does not signal an immediate surge in compromised units. The discovery of this key could influence future developments within the PS5 community.
