The slides from my @0x41con 2023 talk are now available: jonpalmisc.com/2023/07/31/get… 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.

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

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.

@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 Hey, just went to check, is this supposed to be a working link?

Quick update to arm.jonpalmisc.com: - 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 :)

@bluefalconhd_gh It looks awful, but it’s here: arm.jonpalmisc.com/latest_sysreg/… Basically meant to be searched with CMD-F as a fallback for when the search is wonky

@jonpalmisc You already have a sysreg list? I saw a blue link on one page but clicking it brought me nowhere.

@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

@jonpalmisc I didn’t realize this was your site!! It’s an excellent reference. I would love a nice and easy to browse sysreg list!

The OG is cooking for 2026. Stay tuned. 0x41con.org

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.

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: github.com/jonpalmisc/ibis

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.

@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

Had a dream that there was a Ghidra update last night. It's so over.

Just released a short writeup for the A9 version of the Trigon exploit, which involves getting code execution on a coprocessor before exploiting the kernel - enjoy! alfiecg.uk/2025/07/16/Tri…

Two new arm.jonpalmisc.com updates: - the search bar should now return better results thanks to better page indexing; and - when it doesn’t, there are now “all instructions” and “all registers” pages you can CMD+F manually.

I like em dashes, and I hate that some people now take them as evidence of text being AI generated.
