Today I presented at #hackbcn some practical usecases integrating language models for reverse engineering purposes with #radare2 eliminating the learning curve, decompiling high level abstractions, automating complex tasks and finding vulnerabilities with local models. Check out my slides at https://radare.org/get/r2ai-hackbcn2025.pdf

Missed out on the action at #r2con2024 in Barcelona? #NowSecure researcher and #radare2 author @pancake put together a recap of all three days, including all the recordings, slides, and GitHub repositories.

A huge thanks to everyone who joined us and made this comeback event a success after a 5-year break! #r2con #radare #frida
#radare2 - 5.9.6 - codename "corteza" is out!
More than 300 changes in 2 months! Read more about the changes in this release: https://github.com/radareorg/radare2/releases/tag/5.9.6
After some tweaks here and there, native xrefs to the object pool in Dart binaries are finally working. The metadata parsing still needs a patched fork of Blutter (android only), but at least the relevant parts are merged into #radare2 master ( https://github.com/trufae/blutter-docker ) #dart #flutter #reverseengineering
I got decai (radare2's AI-assisted decompiler) to work with a local model, and tried it over a basic Caesar implementation in C and in Dart.
To be honest, I think the conclusion is that the model I selected is not good enough ;) but #r2ai and #decai are really great tools. Read my post to understand how to install, configure and use. Or RTFM :P

many thanks to @Pancake for his patience! "it's not working on my laptop", "try this then" etc

as always, i tried to keep the bullshit to a minimum #radare2 https://www.nowsecure.com/blog/2024/09/11/reversing-ios-system-libraries-using-radare2-a-deep-dive-into-dyld-cache-part-1
www.nowsecure.comReversing iOS System Libraries Using Radare2: A Deep Dive into Dyld Cache (Part 1) - NowSecureA big part of that happens via dynamic binary instrumentation, thanks to Frida. This requires a deep understanding of how the system works, apps interact with it, and data flows. That understanding can only be achieved by reverse engineering mobile apps and system components.
