Built my dream DOS and early win95 machine. Hardware Roland MT32 sound emulation and a 3DFX Voodoo 2 card 🤓😎P233MMX 32mb ram.
we are in the golden age of RE, with so many frameworks and resources, there is no better time to create YOUR own custom tools and workflows. RE is about solving problems and building your own unique workflow to do that. 1/2
As promised, and thanks to @yates82 and @jeppojeps for the help, here you can find Dragon-tales: github.com/Fare9/dragon-tale…
I hope the tool can be useful for someone else, and we will continue improving it with support for different architectures.

I have done the second part of the analysis of VMProtect with Claude and Dragon-Tales, after the improvement I had after chatting with @k0mkc, and after @mr_phrazer & @nicolodev talk, I have gone deeper into Virtualization+Mutation, as well as discovering the GOT in the VM

"Software protection is futile, AI will break it", they said.
But, does it? how?
To shine some light read about Rémy Salim's experiments in "Defeating AI-Assisted Reverse Engineering"
Where is the fair play, Claude?

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/gdbs…
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

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 :)

I was reading some old PC mags and came across these adverts. does anyone remember these hasp dongle thingies? maybe @halvarflake I remember they were often talked about in RE forums in the late 90s but I never encountered such a device myself so never got to play with them
