In the Reverse Engineering world, we have a rule: You don't own it until you can take it apart.
The same applies to Artificial Intelligence.
We are currently drowning in API wrappers. Everyone is "building AI apps," but very few people are looking at the wiring underneath. To truly understand modern LLMs, I decided to stop using libraries. I went back to the drawing board to build a custom architecture from scratch.
Meet SARAN (Shallow Auto-Regressive Attention Network).
It’s not designed to beat GPT-4. It’s designed to be transparent. 🔹 I built a strict 15-stage computational graph. 🔹 I manually implemented backpropagation to trace the gradients. 🔹 I scaled it to a 354M parameter model to watch how it learns.
I’ve documented the entire build log—including the architecture decisions and the "why" behind the math—in my new engineering newsletter, Bits & Neurons.
If you want to move beyond the hype and understand the mechanics of AI, read the full breakdown here: https://mytechnotalent.substack.com

Trump may be beginning of end for ‘ #enshittification’ – this is our chance to make #tech good again by #CoryDoctorow
There is only one reason world isn’t bursting with wildly profitable products and projects that disenshittify #US’s defective products: “anti-circumvention” law bans #reverseengineering that is the necessary prelude to modifying an existing product to make it work better for its users (at the expense of its manufacturer). But the Trump #tariffs change that.

Hello and welcome to the second installment of #nakeddiefriday in this new year!
Today's image is of a M37620E8FP, a Mitsubishi microcontroller. This should be one from "group 7620" but I did not find a datasheet for this one. Custom markings on the package likely identify the ROM and its version.
Full-res pano: https://siliconprawn.org/map/mitsubishi/m37620m8-/infosecdj_mz_nikpa40x_50p/
Many thanks to @RueNahcMohr for supplying this sample!

Can anyone recognize this IC? Looking for its p/n and a datasheet ideally. Handles all the analog audio paths in a portable cassette player.
EDIT: A knock-off of Mitsumi LAG668F.

🦀 Looking for Rust malware samples to practice analyzing? Our Rust Malware Sample Gallery just received a major update, with 20 new families added! https://github.com/decoderloop/rust-malware-gallery
The Sample Gallery collects links to articles about malware written in Rust, organizes them by malware family, and includes a download link to a publicly available sample for every malware family. This is a resource for any malware analyst who wants to get hands-on with real Rust malware.
The last time the Sample Gallery was updated was almost 2 years ago, in January 2024. Since then, there's been an explosive growth in new Rust malware, including all of the following families that are now in the Sample Gallery:
SPICA, KrustyLoader, RustDoor, SSLoad, Fickle Stealer, Cicada3301 Ransomware, RustyClaw, Embargo Ransomware, RustyAttr, Akira Ransomware (both the Akira_v2 and Megazord variants), Banshee (Rust variant), RALord Ransomware, RustoBot, Tetra Loader, EDDIESTEALER, Myth Stealer, Rustonotto, RustyPages, ChaosBot
This is nearly one new Rust malware family observed in the wild, every month. Rust as a programming language for malware is here to stay!

Just dropped: my RECON 2025 talk on Rust library recognition in malware! 🦀
I present RIFT—a tool that tackles one of the trickier problems in modern malware analysis, rust library recognition in malicious software.
