Today is my last day @google. I’m sad for leaving such a talented team, but excited for what’s next!

[Daniel Púa @devploit]

I totally agree with the measures taken by Codegate in its CTF and I wish they would start to be done more often to control this kind of cheating (at least in important competitions).

“io_uring vulnerabilities were used in ALL the submissions which bypassed our mitigations.”

sounds about right

CVE-2023-2008 - Analyzing and exploiting a bug in the udmabuf driver by @dialluvioso_ and @esanfelix https://t.co/I4rqlpkcSx

I'm really excited to see Apple's analysis of the SockPuppet bug I reported a few years ago is now published. It was quite a powerful bug and a lot of work has gone in behind the scenes on XNU to make bugs like this harder to exploit: https://t.co/EUy1Hmtm3v

First post of my WNF research is out! It covers WNF internals, APIs, structs and some RE’d stuff.

It’s not complete since userland structs are constantly changing and I did not RE’d everything, but will try to keep it up to date!
