Two developers, nas and proxima, have gotten a hold of the PSVita Webkit exploit and have it working with PS4 firmware 1.76. Proxima has stated that even though the exploit is one in the same, it was actually developed in a separate tandem and not based off of the exploit.

They have released a proof of concept code, with several examples provided that includes a module dumper and a tool that is used to create an advanced ROP code. Outside of these devs, there are not any confirmed reports of results from the proof of concept, but Wololo vouches for them and they are reported to be trustworthy as well as the POC is said to have solid looking code. Reports will be posted as they come in.

As per usual, this will not be of much benefit to the average end user, except to confirm if their PS4 can be exploited. This release is more important for devs, who would like to further explore the PS4 and tinker around with the tools. The release is the first of it’s kind for the PS4 and will be greatly appreciated by the community, as any exploit can eventually lead to a full hack.

Sony has reportedly patched the Vita exploit and has already announced new firmware 2.oo to be released next week for the PS4, so it may be wise to put off updating, as nobody likes to protect exploits and software vulnerabilities like Sony.
