"In mid-2022, @Google Project Zero was provided with access to pre-production hardware implementing the ARM MTE specification. This blog post series is based on that review, and includes general conclusions about the effectiveness of MTE as implemented"

Sharing another V8 Sandbox design document more widely: https://t.co/h29nL4uBEM
This one discusses how to protect code pointers - probably the most performance sensitive part touched by the sandbox - with (almost) no performance overhead.

Here are my slides from my @0x41con presentation on Apple’s Lockdown Mode:

https://t.co/GQP0uIXbBC Enjoy 🎉

⚠️ Ironically the slides won't load when you have Lockdown Mode enabled 💀

https://t.co/RNvUDWV8Jl SSH agent forwarding just became even more dangerous. 😂-- leave it to the creative minds at Qualys to turn a series of dlopen()+dlclose() calls (of unrelated/benign shared libraries) into arbitrary code exec, hats off!

[0x41con @0x41con]

If you squint hard enough, you'll see you were there! I hope you all had a great time. Till next time! 😎

[~ @xerub]

The @0x41con lives on because of the hardcore diehard fans it gained over the years who offered to organize and keep it alive. It takes time, effort & money to give you the experience for free.

Mad props @Simone_Ferrini, @f_roncari, @jndok for hosting the 4th ed. It was amazing!

[Filippo Roncari @f_roncari]

It was an honour to organize with @xerub + @Simone_Ferrini + @jndok this 🇪🇸 edition of @0x41con, arguably the world's best conference for research quality. Shoutout to @xerub that made it possible, to all the speakers and to all the attendees who made it special 🫶🏼 #0x41con

[Blacktop @blacktop__]

I presented my Lockdown Mode research at @0x41con today and it was a dream come true ❤️ I started my iOS research journey ~5yrs ago & always dreamt of just attendin let alone presentin with such legends. This has been a tremendous honor! Thank u @xerub & @Simone_Ferrini et al.
