Oh, and .. one more thing: if the fileset.0x* names confuse you in #jtool2 output, be confused no more.
Extracted filesets are now correctly named, completing jtool2's (formerly, @Morpheus______ 's joker) "Kextraction".

patrickwardle: RT @Technologeeks: #Jtool2(.0.3) update: Now rebuilds filesets (read: kExt) by patching LC_SEGMENTs/LC_SYMTAB, and rebuilds kernel's main portion over full kernelcache, so you can inspect kexts as well as kernel __DATA_CONST (which technic…
#Jtool2(.0.3) update: Now rebuilds filesets (read: kExt) by patching LC_SEGMENTs/LC_SYMTAB, and rebuilds kernel's main portion over full kernelcache, so you can inspect kexts as well as kernel __DATA_CONST (which technically resides outside kernel's main fileset portion)
.@Morpheus______ 's #Jtool2 updated with fixes for new machO features and - most importantly - better analysis of #iOS16/Mx-macOS #kernelcache - bringing 1,450 more symbols (PPL, mach traps, syscalls & more), "illuminating" XNU's darkest corner for all!

Apple's new #iOS16 #kernelcache format confusing your #IDA or #Ghidra?
We've updated #jtool2 to not only support, but also analyze the new kernelcache (with joker lib) and keep the best mach-O command-line parsing tool up-to-date!

Quick fixes for @Morpheus______ 's #Jtool2 have now brought its --analyze feature up to date with XNU-81xx - updated system calls, MIG routines, fixed a segfault

Still in our todo list - M1 binary, more symbols, and shared cache..
More to come soon.
Do you use @Morpheus______ 's #Jtool2 or other #macOS/#iOS tools , and have issues? Need bug fixes? M1-build? --analyze (for kernel caches) or --symbolicate (for panic) fixes?
Let us know over DM! We maintain the tools now, and can put in fixes or updates.
#4/n: This marks the absolute, final updates to the books, as well as my beloved #JTool2 (*Sniff*, AAPL, won't you take it from me already? 😢 ). As promised - Hard cover boxed sets (which are *really* awesome, but I'm biased) will ship by the end of the month.
#Jtool2 (CAI) is becoming future proof: Not only does it support all Code signing algorithms (SHA1 through SHA-512!), but also #joker - the #kernelcache #symbolication module - now uses an external argument pattern matching file, to easily edit and add any pattern you like!
Some iOS 13.2 kernelcaches are apparently BVX2 compressed (and others still have other surprises ;-)
#jtool2 final release (which I still owe the world, before I can put Darwin behind me) will extend native less/lzvn compressed kernelcache handling for this too. Stay tuned.
#Jtool2 (BDA) update: bug fixes, more iOS13 symbols. And - finding references to addresses in a hard-fused kernelcache, even if the pointer is tagged.
Can your non-free disassembler do that? Maybe. Maybe not. Or maybe in its next version it will ;-)

Just realized #MacOS #kernelcache Mach-Os are malformed & break otool/nm/etc. Since for CLI-folk #otool -tV is a necessary evil (for intel), #jtool2 can (again) remove any load command. Also useful for stripping code signatures. Full segedit coming soon.

Wow! XNU-6041! 1733 is the new 1469 :-)
#Jtool2 finds "only" 3,315 symbols, but detects three new syscalls, several new mach_port, task and memory_entry MIGs, and a new MIG subsystem (8,000) - if you see these magically appear in IDA - know where they came from...
more soon!
