"DisARMing" code - an exploration into systems programming, #debugging & #reverseEngineering on #Linux/#Android/#Darwin and #Aarch64! 510+ pages #book in COLOR(!) NewDebuggingBook.com for details, because there's more to detail than the margins of a Twitter message can hold.

I never go on Twitter anymore, but today's truly special occasion merits this: *Both* #iOS legends @_p0up0u_ (#KFD!) and @opa334dev (#dopamine!) graced my @offensive_con training, continuing the "Mystery Guest" tradition". I am humbled and grateful! Thank you both so so much!

#iOS #entitlements database updated for #iOS17. With even more executables and, yep, many more entitlements. NewOSXBook.com/ent.jl

*Sigh* Where are the days when one would have to sell a soul to AAPL in order to get XNU sources "hastily" released as a single tarball after more than three months :-)

My #Imjtool (Darwin nightly build) now supports the really simple #RTKit ftab.bin format - For those firmwares which might have it.

In other news, my attempt at a universal decompressor - a.k.a imjtool (nightly build for Darwin) now supports img4 and BVX2 (in addition to zip, lz4, pbzx, yaa, bz2, gzip and much more) so you can decomp the kernelcache and new SPTM from the ios17 IPSW newandroidbook.com/tools/imjtool.…

Congratulations to my favorite Kernel of my favorite OS family for hitting build number 10002.0.40.502.3~1. (I know it doesn’t mean much to most, but after 15 years together, I feel like it’s a milestone :-) I miss you, old friend.

Wen eta Hermès style headband for #visionPro?

#WebKit. Abused by millions.

Namedrop - more ways to share your 0-click. coming soon in #iOS17

Another year, another #macbook air with USB-C on only one side… the same side as MagSafe.. *sigh* Where hast thou gone, Jony Ive?

The #Android #Device #Database now has its first #Snapdragon #Gen2 entry: brand new A13 Nubia RedMagic 8. +PAC, +BTI, -MTE. And, thanks to @never_released , finally an Exynos 2200 as well. ** please contribute device data if you have devices not in db ** newandroidbook.com/ddb

#Imjtool 2.0 β3 inches further towards portable, #Android Universal #image unpacking with PBZX/YAA (AAPL #iOS/#macOS #OTA) now built-in (my code from newosxbook.com/articles/OTA9.…) along with tested ZIP, BZ2, LZ4, XZ, and (highly experimental) .7z support. newAndroidBook.com/tools/imjtool.…

#jtrace (newandroidbook.com/tools/jtrace.h…) updated with full system call coverage for Linux 5.10+ (Android 13) , and new plugins to track Linux (/dev/dri) and Qualcomm Adreno (/dev/kgsl-3d0) #Android #graphics

#macOS/#iOS #Entitlements Database now with Monterey and Ventura entitlements. newosxbook.com/ent.jl With lots of Love (but no Thanks giving) to @Apple Happy holidays :-)

The latest @0x41con v3 (0x43?) was better than ever! Meeting everyone again is already good reason to travel, and Greece was great! My special thanks @_argp & @xerub - and y’all made me actually miss Darwin.. My (shorter of the two) talk slides are at: newosxbook.com/bonus/0x41-16.…

A lot of work has gone into, and is going into jtool2, to keep up with AAPL’s Mach-o Machinations - and it was, is and will remain free. If you find jtool2 useful - This is your chance to show support, and help make it even more powerful for everyone!

Another #iOS version, another #Entitlement Database update. 166 new executables to explore, with Love for my readers @ 17.x.x.x And a spiffy new look for NewOSXBook.com (complete with javascript terminal!) thanks to the super talented @FCE365 (wen eta? ;-) )

#Imjtool now supports Spreadtrum/UniSoc PAC files. NewAndroidBook.com/tools/imjtool.… Also, upcoming #Android #Internals book update (for #Android13 changes) will drop Huawei in favor of UniSoc, as the former are effectively down to 0%, whereas the latter already have 11% market share.
