I'm currently taking a Cybersecurity class at university, and we need to give some sort of presentation regarding something having to do with cybersecurity. (Detailed requirements, I know) I figured since I'm already vaguely familiar with modding a PS4, at least from the end-user perspective, this would be a pretty easy topic to use. Plus, I thought I could always ask around on this site for more information (hence, the thread)
While I'm not looking for an extremely thorough explanation to the extent of being able to set up my own host or try and replicate anything myself, could anybody either give me a brief explanation of what the exploit is doing to give access, or point me in the direction of somewhere I could get this information?
From how I understand it, "userland" is the access that a game/app has to use the console's resources, "kernal" means you have access to absolutely everything. The online part of the exploit intentionally crashes the PS4, and tricks it into using the payload in the USB to restart itself rather than the normal hard drive files. If I'm right on this so far, that's the total extent of my knowledge, and if I'm mistaken, then I knew even less about it that the small bit I thought I already understood.
