I've been working on a side project for some time: autonomous reverse-engineering powered by Gepetto.

I shared some thoughts here (https://blog.kwiatkowski.fr/gepetto-web), and am looking for beta testers to try out the platform.

DM me or reply below if you are interested!

On autonomous reverse-engineering | Borderline

If there's one thing I've been passionate about throughout my career, it's reverse-engineering. I've also enjoyed teaching reverse-engineering for years, either in-person or when developing online courses. One of the things that struck me as time passed by was how much tooling has changed the way we work.

Can someone clarify for me how we went from "don't believe everything you read on the web" to "source: an AI saw it on Twitter"?

Reverser friends, Gepetto has made huge leaps in the last weeks. I now consider it to be a decent IDA Pro agent.

With zero interaction (gpt-5), it solved a crackme all on its own. I opened IDA, typed in the prompt, and it did everything.

Prompt if you want to try it out: Analyze this crackme, starting from the main function, and using all the tools at your disposal, try to figure out what is the expected password. Rename everything you can in the process.

The plan for Gepetto has always been to go further in the agentic direction. I've started exposing the context of the RE session to the LLM.

It may not look like much right now, but ~soon the model will create structures for you from the CLI and recast variables 🤯

Right now, the only tools available are getting the current EA and a function's decompiled code.

It's still bleeding edge, but try it out!

One of the most unexpected and important things I learned working in threat intelligence is: governments will go nuts over maps.
Mislabel something or draw the wrong border and they'll hunt you down like a dog.

Whatever the map says goes in real life.

I guess I'm not getting rich this year either.

I've published a zine on Relationship Anarchy, subtitled "Dreaming in the Belly of the Whale": https://catileptic.tech/posts/relationship-anarchy/

I'm vibrating from head to toe with excitement that I finally put my thoughts into words, all in one place, and I can offer them to others.

This zine is the result of countless excellent talks with lovely folx. It's also the result of reading Victor Vilisov and Slavoj Žižek, as well as many other texts that expanded my mind and nuanced my thinking.

I have this crazy idea: every week, I'll showcase the most bizarre, awkward, ridiculous, or even dark Tor onion websites I come across. What do you think?
