Hacker reveals “Unpatchable” Sony Ps4 / Ps5 Vulnerability
By MYBRANDBOOK
CTurt, a hacker who has been working on game console cracking for a long time, has revealed an “unpatchable” vulnerability in the Sony PS4 and PS5 security dubbed as Mast1c0re.
The vulnerability allows hackers to install arbitrary homemade applications on the console, and exploits a bug in the just-in-time (JIT) compilation used by emulators running some PS2 games on Sony PS4 and PS5, which gives the emulator special permissions to execute the code in the application layer itself.
Hackers would still need to exploit a separate (possibly patchable) kernel vulnerability to gain “full control” over the PS4. But the Mast1c0re exploit itself should be enough to run complex programs. This includes JIT-optimized emulators, and possibly even some pirated commercial Sony PS4 games.
CTurt emphasizes that it is almost impossible for Sony to plug the loophole that enables Mast1c0re as a version of the available PS2 emulator is packaged with every available PS2-on-PS4 game, rather than being stored separately as a core part of the console’s operating system.
CTurt said he disclosed the vulnerability to Sony a year ago through a bug bounty program. However, he claims that Sony has shown no sign of a public fix. The code is constantly writing PS4-ready code (based on the original PS2 code) before the code.
