Hello! Hello. It's #nakeddiefriday today, and I wanted to show you one of the older works. This is an automotive ASIC fabbed for Toyota, part number DF028. I do not know the function of this particular device.

My employer is doing a CTF and a lot of the remaining challenges involve #reverseengineering binaries. Any suggestions on a crash course I can put myself through to try and get some of these flags? The binaries are all Linux.

And hey, since the weather is absolutely abysmal today, I will treat you to another die shot as an extension of #nakeddiefriday.
This is КР1810ВМ86, an otherwise identical clone of Intel 8086 made by Soviets at an unknown plant.
The 8086 was extensively reverse-engineered by @kenshirriff -- give his blog a read!

🦀 I'm excited to announce that I am starting a training firm, @decoderloop, focused on providing Rust Reverse Engineering training! https://decoderloop.com/
The tools, techniques, and resources that reverse engineers have were built for the era of C. Meanwhile, malware authors and software developers alike are rapidly switching to modern programming languages such as Rust. Decoder Loop is here to fill the knowledge gap and level the playing field, for reverse engineers facing modern binaries.
We hope to come to a conference near you, next year. If you'd like to stay notified on upcoming trainings: follow us at @decoderloop, or sign up on our mailing list at https://decoderloop.com/contact/#training-signup-form
I'll also be at @ringzer0 COUNTERMEASURE on November 7 in Ottawa, Canada, giving a Rust RE focused workshop! Come say hi if you're there, and let's chat Rust RE!

Hi there! This is #nakeddiefriday again!
Today I'd like to present you one of frequent sources of pain for C64 owners, the infamous PLA. This is MOS 7700R2. They failed way too often, and considering this is custom silicon, the only option was to get another one of the same.
Many thanks to @root42 for providing this sample!

Happy #nakeddiefriday to everyone! Let's get this ball rolling.
Today we have a real classic, the MC6845 by Motorola. This is a CRT controller chip used in quite a few video adapters back in the day.
Thanks to @gloriouscow for suggesting this one! We'll do a short thread looking around.

Hello Anti-Ai, Anti-Tech, Anti-Fun Complainers,
Go ahead and keep being miserable while the rest of the world moves on without you; leveraging advanced technology to further the human race, engaging in complex scientific research with supercomputers, solving complex medical diagnoses, improving the success rate of invasive surgical procedures, and continuing efforts to create the world which you already benefit from — despite all of those misinformed views about this evolving technology you refuse to understand.
> "but.. the media told me that skynet.. and those evil chatbots.. something about hallucinations.. and our burning desire to anthropomorphize machine intelligence".
Anyway: https://zenodo.org/records/17196870 here's some recent fun with LLMs.
> [Kelsi Davis] decided to port the Macintosh System 7 OS to run on native x86 hardware, which would be challenging enough with full access to the source code. However, she instead performed this task by analyzing and reverse engineering the System 7 binaries with the aid of Ghidra and a large language model.
>
> Soon enough, she had the classic System 7 desktop running on QEMU with a fully-functional Finder and the GUI working as expected. [Kelsi] credits the LLM with helping her achieve this feat in just three days, versus what she would expect to be a multi-year effort if working unassisted.

💥We had 18 years to solve the IOLI crackmes!
Today Pau Oliva (pof) released their source code! Those simple crackmes to learn the basics of reverse engineering can now be recompiled for new targets and update all the tutorials from the r2book \o/ #radare2 #reverseengineering #crackmeshttps://github.com/poliva/IOLI-crackmes
