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 nsec.io/session/2025-reconstru 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: youtube.com/watch?v=UwJgS32Q6A

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.)

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.

“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.”

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...
