PS4 Firmware 4.55 Public WebKit Exploit Has Been Modified To Work With PS4 Firmware 5.50

Recently it was revealed that hackers have managed to exploit PS4 Firmware 4.55 to run Linux on it using the PS4 Linux Loader payload tool, however, the exploit only worked on a few systems with firmware 4.55 and now one hacker has managed to work the same exploit for PS4 Firmware 5.50 to run Linux on it.

While Sony had patched out the exploit from its kernel in its PS4 Firmware 5.50 but, qwertyoruiop has managed to rewrite the public WebKit exploit to work on systems which have been updated to firmware 5.50.

According to qwertyoruiop, the hack is 100% reliable and should allow for the use of Linux on PS4. However, this could potentially open up the system to being jailbroken and being able to run pirated games.

Speaking of exploits, a new Spectre Based Exploit has been uncovered that kills the software guard extensions (SGX). Researchers at Ohio State University have uncovered another Spectre Based Exploit called SgxPectre which disables the SGX.

According to Intel, the company is aware of the new Spectre based exploit and added that they will be rolling out “updated software development toolkit for SGX application providers” by March 16 to combat the newly discovered exploit.

We are aware of the research paper from Ohio State and have previously provided information and guidance online about how Intel SGX may be impacted by the side channel analysis vulnerabilities. We anticipate that the existing mitigations for Spectre and Meltdown, in conjunction with an updated software development toolkit for SGX application providers — which we plan to begin making available on March 16th — will be effective against the methods described in that research. We recommend customers make sure they are always using the most recent version of the toolkit

While the exploit can potentially open up PS4 to be able to play pirated games but, we don’t encourage nor support piracy.
