Please don’t take this or the replies as justification to personally attack anyone, this is mostly just a consequence of the times we’re in. It just makes me a bit sad and the situation is unfortunate.
LLMs fracturing the console research space feels like a good litmus test of where we're at lmao. The future is slop and the fun is dead.

But r/blackops2 said devkits/testkits have special magic that makes them impossible to ban so this can't be true
There's been a rumor going around that the dev/testkits that were banned were banned because they used a specific update file, the truth is the kits that were banned were banned because they were cheating online and anyone that suggests differently is coping

Method we used (>5 years ago, now) on ps5 to fiddle with mp4 and hv memory: github.com/fail0verflow/pros… hope it helps for linux!

Some people already know this, but thought I'd mention here too... unfortunately basically all of my low fw PS5s got stolen recently, so I'm not sure what my future in console research will look like. Replacing this stuff might be too be difficult & expensive to be worth it :(

My @dayzerosec co-host zi and I are giving our 1st training @ hardwear.io with a focus on attacking security hypervisors! Trainings are something we've wanted to do for a while. Take a look and share to those who would be interested :) hardwear.io/usa-2025/trainin…

We have a training by @SpecterDev & Zi on Attacking Hypervisors From KVM to Mobile Security Platforms hardwear.io/usa-2025/trainin…
I've published a write-up on reversing and analyzing Samsung's H-Arx hypervisor architecture for Exynos devices, which has had a lot of changes in recent years and pretty interesting design. Hope you all enjoy :) dayzerosec.com/blog/2025/03/…

RE: byepervisor do people care enough about not wanting to use rest mode and resume to switch the primary exploit for byepervisor to the jump table one? its higher maintenance and possibly slightly less stable but would be slightly more convenient to run I guess

I've published the repo for Byepervisor (we love named vulns out here). Contains exploit implementation for two PS5 hypervisor bugs for 2.xx and lower. Slides from the talk + vod should hopefully be published soon. github.com/PS5Dev/Byeperviso…

The PS5's hypervisor has kept the system secure for years—now, vulnerabilities are being revealed. What does this mean for gamers? 🕵️‍♂️🚨 Join @SpecterDev at #hw_ioNL2024 Know More: hardwear.io/netherlands-2024… #ps5 #exploit #hardware

There are a few ways on PS5 to defeat HV. One of methods that I've found was related to APIC: struct apic_ops is located in RW segment of kernel data. With KRW you can overwrite a function pointer inside it like xapic_mode and get into ROP, for example (just need to bypass CFI).

Feels great when an idea can finally be tested and works out after like a year :) Shouts to ChendoChap for working out the ROP chain. Protip: staying < 3.00 is a good idea.
