@Patokereal @momo5502 you can probably use https://t.co/tyEJie6Z9w to help clean up the rotation logic

[Robert Yates @yates82]

@momo5502 I would be curious how this is implemented/protected in various systems. anyway, have fun :)

[Robert Yates @yates82]

@momo5502 i've also never looked at anti-cheat, but ive often pondered about how it would be designed. in my mind the cheater detected status being sent back to the server and where this status/msg is constructed deep In the chain would always be the weakest point.

@RandalLinden hihi thanks mate

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. :) https://t.co/Bxo4Zj2umy

@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

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

[Robert Yates @yates82]

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

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

@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.

@vector35 where did it go? did you leak api keys again :)

@DiscussingFilm @EsfandTV add this one to your next boomer month pls :)
