@yates82 Awesome work!
You might think nobody needs it *today* ... but who knows when it will become important for someone and you've already provided it!
Well done 😀

I made a lame gdbserver for basic remote debugging old 32bits exes on old windows versions like windows 98/XP. works with binary ninja's "GDP RSP" adapter. probably nobody needs this but me, but now it exists, so there. :) github.com/robert-yates/g…

@dodo_sec true)) the only time i use graph mode is if you ever have a binary obfuscated by inserting jmps between every instruction up and down the whole code section, then swapping into graph mode makes it readable in a linear way instantly
English
Assembly in graph instead of text mode is diabolical (this is very cool)

I broke Kindle's DRM protection tonight through a mix of static and dynamic analysis. AES key is derived from accountSecrets, kindle device ID, and voucher path. Book is decrypted in parts using OpenSSL from Ion blobs and then decompressed with LZMA.

@allthingsida ahaha yes !! IceExt addon for dumping memory to disk and also for playing mp3s whilst the kernel is frozen, was truly amazing)))

@yates82 Then having to fix your clock to compensate for the time you spent in Ctrl-D.
Don’t forget to get the patch to enable ring0 mp3 player too ;)
Good old days.

This is how boomers did debugging :D, this shows loading the ring0 softice tool on windows 2000, setting some style options, then setting a system wide API breaking point and following a stack string decryption

Ok, ida-frustrated 0.0.2 has now some cool animations and scenes. Press Ctrl-Alt-T in any widget to get a random visual. It really would uplift the frustration! ;)

Put together a "frustrated" mode for IDA ;p (Still working out the animation quirks)

I wrote a thing. if you are interested in obfuscation/de-obfuscation and compilers, but perhaps don't have a tangible experience with it, then i hope this story will be interesting to you and teach a few things along the way (-:

Obfuscation vs The Optimizer: A Battle in LLVM Middle End. @yates82 shows us how the continuous improvement of the LLVM optimizer defeats naive code obfuscation, and how the obfuscator can fight back. An eternal fight in which all victories are ephemeral blog.quarkslab.com/obfuscation-vs…

@dodo_sec this reminds me, i really need to watch fawlty towers again

along with intel's new hardware they have released "Intel® Binary Optimization Tool". its being marketed as a way to enhance perf for gaming. They have profiled a bunch of games and with that info do profile-guided DBI basic block order rewriting to increase IPC. pretty wild.

im starting to fall back in love with IDA ... with 9.2's microcode viewer and now especially 9.3's ability to interactively manipulate the microcode !!! along with being able to render microcode flow graphs with use/def chains, i feel in conflict. aaaaaa :)
