The PS4 Jailbreak is not apparently anything brand new as other hackers have announced that you could have accomplished the task using the Cobra USB game emulator. Some indicate that hack was actually fake, but there is no actual confirmation of that information.
Right now, the Cobra Team is working on a hack for the PS Vita hand held gaming system. All of the hacking attempts that are being made by CTurt are being posted on GitHub and that allows the public to follow along during the process essentially learning it as well.
Since the PS4 Jailbreak is not completely released to the public yet, Sony has time to fix the issue and it will do just that. The odds are good that developers for the company are also on the forums and other websites learning what they can about the hackers and what they are up to.
