The default io plugin of radare2 now supports fifo files, which means that you can use the funny bird operator: $ r2 <(o )

The revamped filesystems talk at #r2con2025 presented lots of juicy new features for #forensics. 🎁 New FileSystems: UBIFS, HaikuFS, SSHFS 😎 Frontends: MidnightCommander-style, rafs2 cli tool, iaito widget 🪽New Features: display headers, diskaddr2fspath Video 📼 www.youtube.com/watch?v=mf2h...

6h to go! #r2con2025 www.radare.org/con/2025/

Happy radare2 6.0.4 release day infosec.exchange/@radareorg/1...

📣The list confirmed talks for #r2con2025 are now public! How does it look? 🧸Bear in 🧠 mind that the list is incomplete because the CFP is still open and there are some unconfirmed talks still to be published! ⚓️ radare.org/con/2025

One of the demos is here: asciinema.org/a/pBPEaJhp6c... It demonstrates the automatic mode of r2ai, where we can ask a question whose answer requires to read/understand several functions of the binary. #radare2 #r2ai #AI #LLM

🍏 Merged class dump support for iOS26! Testing with different kernels and some fuzzing is probably needed before the release, if anyone in the mood for that! Kudos to @[email protected] for the PR! github.com/radareorg/ra... #apple #ios #reverseengineering #radare2

Hey, I'd like to share the best talks/papers/videos/tools/CTF challenges I encountered in 2025 H1. This is the official "Cryptax Award 2025 H1" (lol). Congrats! cryptax.github.io/nomination-2... cc: @elbsides.bsky.social @northsec.io @radareorg.bsky.social @bsideskrs.bsky.social

Just arrived the #radare2 book! I will finally had a chance to learn it! #reverseengineering #books

🚨Friendly reminder: The #CFP for #r2con2025 is still OPEN! There's plenty of time before October 24th, but if you want to talk about anything related to #radare2, please submit your talk ASAP! ✨ Let’s make this edition even better! 🚀 #infosec 👉 radare.org/con/2025/

📦 In my last video for r2tv I introduce r2pm, the package manager. Learn about how to create, search and install plugins and tools for radare2! ▶️ 10 min - www.youtube.com/watch?v=N31b... ▶️ 20 min - youtu.be/DbVBbxOL7KY

📺 In the second video for #r2tv I explain the caveats of injecting null bytes in the process environment with rarun2, inspect the stack with r2frida and bypass limitations encoding the payload with ragg2! www.youtube.com/watch?v=-CMH...

📣 📝 We are proud to announce the #r2con2025 call for papers! Expect it online and around Nov/Dec! Submit your talk proposals and stay tuned for updates! 👉 radare.org/con/2025

We can finally spin donuts in iaito! 🍩 🍩 (i know, that's an ancient feature request that brings us closer to get 1:1 feature parity with #radare2 ) But it's better late than never! Enjoy 🎉 PD: You can spin as many donuts as you want!

Today I wrote an #r2ai widget for iaito, the official #radare2 frontend.

Today I presented at #hackbcn some practical usecases integrating language models for reverse engineering purposes with #radare2 Check out my slides at radare.org/get/r2ai-hac...

Power #vim users are used to the m' navigation workflow, which was already implemented in the Visual mode of radare2. Now you can also use hjkl and those shortcut keys in iaito to quickly move around the binary without using the mouse! #reverseengineering #ui

Iaito got some improvements in the hexadecimal editor with improved light theme, numeric value edition with endian and different bit sizes, pixelart, monospaced fonts in symbol listings, some more goods will come soon!

Wrote a paper, with Daniel Nakov, on comparing the #quality & the speed of #malware analysis assisted by #r2ai, or without. Spoiler 1: quality is =, speed is ++. Spoiler 2: do not expect to get good results in a single question. arxiv.org/pdf/2504.07574 cc: @radareorg.bsky.social #arxiv #radare2

For those interested in r2mcp, it is now possible to run it locally with OpenWebUI and MCPO. #r2ai #radare2 #reverseengineering #llm

The C rewrite of #r2ai can do auto mode at the same level of the original Python implementation now. Kudos to @dnakov.bsky.social for the effort! #ai #vibereversing #reverseengineering

Despite the need of tests, a refactoring and native charset plugins the multi-byte reencodings like jis7<-> are now working

The new asm.lines.split creates a secondary column in the disassembly view for the backward branch lines making it easier to spot loops and understand the control flow #reverseengineering #disassembly #cli #tui

For Ph0wn Labs, yesterday, we had a 4 level crackme to work on. Watch how easily r2ai solves level 4! (well, don't watch it you don't want the spoil!) asciinema.org/a/B8UalyH6I3... #radare2 #r2ai #AI #crackme #ph0wn

At last! I finished reversing the communication protocol of Linux/Prometei, with AI's assistance. A bunch of hallucinations from the AI, but if you struggle on, in the end, you get the info you want. cryptax.medium.com/communicatio... #linux #prometei #rc4 #botnet #AI #r2ai #radare2

Thursday Feb 13, at SHL (www.shl.contact), in Sophia Antipolis, 7pm, with your laptops. 1. Radare2 @radareorg.bsky.social **beginner** tutorial 2. Very simple CrackMes ... then more complex. Hack Pico le Croco's videophone, lift and door bell. 3. Play prior challenges of Ph0wn CTF

Last weekend I did some improvements for Decai - load custom decompiler pipelines from external json - deterministic mode for ollama, openai and claude - add mistral endpoint. - implement a vector database for embeddings from scratch in C with 0 deps #radare2 #r2ai
