PS4: Qwertyoruiop shares some details on the 5.05 kernel exploit
Hacker Qwertyoruiop was at the 0x41con infosec conference in Romania this week, where he presented the details of his PS4 hacks, in particular how he recently implemented a kernel exploit for firmware 5.05.
Qwertyoruiop has shared a pdf of his notes for the presentation, and it gives some details on the kernel exploit. The PDF can be downloaded here.
It’s an interesting read, but not as detailed as a typical writeup with the intent to explain the full thing.
The details are probably not enough for a 3rd party to release an implementation sooner than what SpecterDev will release, but we learn that the basic of the exploit abuses UMA, the FreeBSD Kernel memory allocator. The notes also give rough details on how he bypassed additional security that is implemented on the PS4 to avoid running the exploit.
Last but not least, the hacker shared some cool GTA V mods he’s been working on with his exploited PS4. In which each bullet he fires generates money on impact.
