Decided I was fed up with my old blog being clunky so I transitioned it to an Astro blog and so far it's been amazing! Check out the new series page for RetailKit: https://t.co/4t9uUo8Ovg

Curious for the folks on PS4 would it be useful if I documented how to set the RTC/Kernel Clock? I have sorted the way to set this clock properly.

Something a bit different from my normal post but I recently put together a blog post on a vulnerability I discovered in Samsung's Account API. With just the username an attacker would get information disclosure that lead to a 2FA bypass. https://t.co/LCL2hp1HdT

I have updated my research into the PS4 notifications: https://t.co/dY6blbuk0Q This mechanism is really just a form of IPC that will just forward buffers to the listening/reading half. You can monitor what is passed around by hooking the kernel part. 😃

"so you spent a year finding a high impact vulnerability?" "Yes, Dave" "and you disclosed it responsibly for $5 and a t-shirt?" "That's correct, Dave"

I can confirm DECI does work on retail environments up to 12.02 and likely up to current 😀

After many life events getting in the way the long awaited part 3 to my RetailKit series is now live! I think part 3 has been my favourite to write, I hope you all enjoy! Check it out! https://t.co/UVqKyUqVvB

For those who were interested I've published the first part of my write up on the PS4 debugger. I'll continue to work on the next parts as I get some free time. 😀 https://t.co/Y6b31IjzUS

It is also possible to get the Mono debugger running on ShellUI though it seems to fight with ShellCore wanting to force kill ShellUI when its halted.

This does also mean that DECI works on a retail kernel. I'm working on a write up with more details soon. 😉

Fun Fact: Contrary to popular belief the PS4's mdbg system is fully functional on retail kernels, Including its debugger capabilities. I've verified this on 9.00 & 5.05.

Hey friends! If anyone has a PS5 on an exploitable firmware I'm looking to get one for research.

Not sure if its possible but does anyone have a dumped shellcore for ps5 4.51? Or the equivalent for ps5.
