500 lines of pure x64 assembly.
Just to create a Vulkan instance.
No helpers. No C. No safety nets. Just raw MASM64 and the Vulkan headers.

This is what low-level graphics looks like when you go all the way down.

In the demo version of Cryo's Dune, Feyd-Rautha Harkonnen was based on a production image of Sting from the Dune movie, but was redesigned before release.

Here's a video of the image of Sting, Feyd-Rautha from the demo version, and the final portrait from the game.

(Let's see how Mastodon handles a very wide video…)

About time we get this #nakeddiefriday going, friends.

Today's exhibit is one ST1305B, by ST Micro. This is a memory card IC with 192 bits of memory on the die.

The die itself is only 1.40×1.18 mm, quite on the small side.

A short thread follows.

Crazy thought… what if your decompiled Objective-C code looked like Objective-C code?

Today's journey: implementing an Objective-C “pseudo-language” view for Binary Ninja.

Next Thursday, May 15 at @NorthSec in Montreal, I will be hosting the workshop "Reconstructing Rust Types: A Practical Guide for Reverse Engineers"! This will be a 3-hour workshop how to approach Rust types and data structures when reversing Rust binaries. See https://nsec.io/session/2025-reconstructing-rust-types-a-practical-guide-for-reverse-engineers.html for more details!

Workshops at NorthSec will be streamed on YouTube Live. My workshop is scheduled for 1300-1600 EDT (UTC-4) on Thursday, May 15 in the Workshop 2 track, in Salle de la Commune. The stream link for all the Thursday Salle de la Commune workshops is here: https://www.youtube.com/watch?v=UwJgS32Q6As&list=PLuUtcRxSUZUrW9scJZqhbiuTBwZBJ-Qic&index=7

Looking forward to seeing folks there!

(Edited since I can't count days of the week apparently: May 15, which is when my workshop is occurring, is a Thursday, not a Wednesday.)

HELLO! And welcome to the #nakeddiefriday on this somewhat rainy day.

Today's guest is a variation on the serial EEPROM theme, one MDA2062 made by ITT in Germany. I'll do a short thread.

My latest blog post: I'm presenting at the 2025 Open Hardware Summit

https://mikecoats.com/presenting-at-ohs-2025-cta/

I'm excited to announce that in one month's time I'm presenting at @oshwassociation's Open Hardware Summit 2025. My talk's titled "VanSpoof and F**dG3ar: Reverse engineering proprietary bike components to prevent e-waste" and covers everything involved in designing replacement, open source, parts to repair VanMoof e-bikes.

New blog post: reverse engineering the firmware file format of the Samsung NX mini / M7MU.

Thanks to @nina_kali_nina and @IgorSkochinsky for inspiration and support!

Let's get this #nakeddiefriday started, people!

The guest of today is one TMS70C42A by TI. It is a 8-bit MCU carrying 4KB of ROM and 256B of RAM, with three timers and a UART.

This particular die was bit by gremlins, and a small part of it is missing; nothing crucial though. Let's have a walk around.

“The invalid 68030 instruction that accidentally allowed the Mac Classic II to successfully boot up”

"This is the story of how Apple made a mistake in the ROM of the Macintosh Classic II that probably should have prevented it from booting, but instead, miraculously, its Motorola MC68030 CPU accidentally prevented a crash and saved the day by executing an undefined instruction.”

https://www.downtowndougbrown.com/2025/01/the-invalid-68030-instruction-that-accidentally-allowed-the-mac-classic-ii-to-successfully-boot-up/

Managed to put this device in bootloader usb upload/download mode.

But didn't find any sdk/tool that describe/implement the protocol.

From what I've overlooked in the bootloader, it's quite a simple one, so it will be easy to implement.

But man, it's just a waste of time.

Please, manufacturers, release the sdks...
