“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.”

Reverse engineering the obfuscated TikTok VM

https://github.com/LukasOgunfeitimi/TikTok-ReverseEngineering

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...

Got the BGA63 adapter I ordered for the XGecu T48 this morning. If there's ever been an adapter that needed to come with a pack-in user guide it's this one. It's a combined BGA48/BGA63 adapter and the "combined" part is that you have to transfer the whole thing from one bare circuit board to another when you want to switch.

... so after having had to crawl around on the floor looking for those 48 tiny spring loaded pins that easily drops out when you don't have such a guide I finally managed to read out the NAND from a new IoT device I'm targeting atm.

Good: Not encrypted
Bad: As I had guessed, I don't think this is where the main CPU keeps its code

... but let's see where this can take us.

Hello! I don't want to #GetFediHired (yet?), but I am looking for contacts who can help me connect and offer a reality check on a potential new career path by telling about their experiences.

I'm currently working as an embedded software engineer , but I'm exploring a transition into IT/OT security — ideally working as a pentester or reverse engineer focusing on embedded devices, IoT, or SCADA systems .

My latest blog post: VanSpoof v1.0

https://mikecoats.com/van-spoof-v1-0/

I'm happy to announce the v1.0 release of VanSpoof. My VanMoof X3 now starts up, without an e-shifter connected, and does not show an Error 44 status! The bike thinks it's connected to a working, functional, e-shifter!

Today we broke 12k stars on #GitHub remaining #1 on Reverse Engineering there and #1 for, “Reverse Engineering Tutorial” on Google. Thanks again for all of your continued support to help get new folks free training on #ReverseEngineering for everyone! https://github.com/mytechnotalent/Reverse-Engineering

There’s a new entry in our #Rust tool suite designed to assist with #reverseengineering and #vulnerabilityresearch against binary targets!

Ah yes, nothing screams "cutting-edge tech genius" like spending 68 minutes reverse engineering a fan to escape the tyranny of its app. Instead of enjoying clean air, let's devote our weekends to making sure our air purifier can join the unified utopia of Home Assistant—because who needs a social life when you can have a cloud-free smart home?

"Donald Trump’s tariffs demand a response. Around the world, that response has defaulted to retaliatory tariffs — a strategy with severe and obvious drawbacks. After years of pandemic shocks and greedflation, people around the globe have severe inflation fatigue, and few governments are eager to risk further price hikes. And while the world is rightly furious at Trump’s talk of annexation and other belligerent acts, that anger is unlikely to translate into popular support for higher prices on everyday goods. If there’s one lesson that politicians everywhere have metabolized over the past twenty-four months, it’s that any government that presides over inflationary price rises is likely to be out of a job come the next election.

Luckily there is another policy response to tariffs — one that will substantially lower prices for America’s tariff-clobbered trading partners while incubating profitable, export-oriented domestic tech firms. These firms could sell tools and services to local businesses, to the benefit of the world’s news and culture industries, software firms, and consumers alike.

That response? Repealing “anticircumvention laws” that prohibits domestic firms from reverse-engineering “digital locks.” These anticircumvention laws stop the world’s farmers from fixing their John Deere tractors; they stop mechanics from diagnosing your car; they stop technologists from creating their own app stores for phones and games consoles."

Comparing #meta #llama 4 (maverick / scout) vs #qwen 32b for decompilation purposes #r2ai #reverseengineering
PD: groq is the best place to try all these models if you don't have the hardware
PD: qwen-qwq reasoning takes more time, but improves the output, much better than openai/claude/meta for decompilation usecases

If anyone is curious about r2mcp, yes, it now runs in local with openwebui and mcpo #r2ai #radare2 #reverseengineering #llm
