The slides from my @0x41con 2023 talk are now available: https://t.co/SpBoAhGA2X

They were primarily designed to supplement my speaking (and the PDF doesn't have animations), but you may still find them useful. Reach out if you have questions.

Had a lot of fun reversing Coruna over the last couple weeks and decided it would be worth to write it all up before I forget - so enjoy :)

0x41con 7

Mad props to Anna and @qwertyoruiopz for hosting and organising this edition!

Kudos to all the speakers!

And thank you all for being part of it!

[jonpalmisc @jonpalmisc]

Another great year of @0x41con, credit to @xerub and @qwertyoruiopz for keeping the tradition alive 🔥

@jonpalmisc Solid recipe. I recommend adding the optional chocolate chips.

[jonpalmisc @jonpalmisc]

can anyone vouch for the brownie recipe in the Dyld shared cache?

0x41con 7th edition, Napoli, 23-24 April. Expect fireworks at random times! Scientists still unsure why they occur at 3:47pm on random Thursdays.

[jonpalmisc @jonpalmisc]

@bluefalconhd_gh Unfortunately not. I don’t think they are links in the official documentation either, IIRC. They are just highlighted differently since the info is available that it’s a reference.

[jonpalmisc @jonpalmisc]

Quick update to https://t.co/N7QuyNMkvU:

- Docs updated to 2025.09 revision
- Some visual improvements
- Maybe better search(?) (you tell me)

Should be strictly improvements, but lmk if anything seems to have regressed :)

[jonpalmisc @jonpalmisc]

@bluefalconhd_gh It looks awful, but it’s here: https://t.co/uqgPGY6uDz

Basically meant to be searched with CMD-F as a fallback for when the search is wonky

[jonpalmisc @jonpalmisc]

@bluefalconhd_gh Thanks! Anything in particular that would be useful regarding the sysreg list? There’s already the search bar (which has its problems, I’m well aware) and the big listing page (as a crutch). Just curious to understand the use case

The OG is cooking for 2026. Stay tuned. https://t.co/xbEUptRJy6

[jonpalmisc @jonpalmisc]

Still a WIP, but should be useful so far. Would also like to look into how microkernel iBoot works some more and see if there's any improvements that can be made there.

[jonpalmisc @jonpalmisc]

For whoever might be interested, finally got some time to put together an iBoot & SecureROM loader for both Binary Ninja and IDA that maps segments (TEXT, CONST, DATA, BSS) correctly:

Search continues to be a bit of a nightmare—one day I'll write a better library but for now I'll keep fighting Pagefind...

P.S. If anything seems wonky, try emptying your cache.

[jonpalmisc @jonpalmisc]

@hexacon_fr and @objective_see were a blast—it was a privilege to see so many friends again at both conferences and to make many new ones :)

@m40282845 Sounds more like a nightmare
