DWARF as a Shared Reverse Engineering Format (lief.re)
When reverse engineering binaries, we could want, at some point, to share the reverse-engineered information with others. The DWARF format, originally designed to hold debug information associated with the original source code, is also well-suited for storing reverse-engineered informations such as structure, function names.

Why do Windows functions all begin with a MOV EDI, EDI instruction? (2011) (microsoft.com)
If you look at the disassembly of functions inside Windows DLLs, you’ll find that they begin with the seemingly pointless instruction MOV EDI, EDI. This instruction copies a register to itself and updates no flags; it is completely meaningless. So why is it there?

Dolla dolla bill, y'all: Reverse engineering a banknote validator (fromnothing.blog)

JavaScript Obfuscation Through File Stream Side-Channel (gavide.dev)
I was recently reverse engineering a website that attempts to block devtools and obfuscates its API through HTML/CSS/JS blobs. Suddenly, a random thought crossed my mind: “If one goes as far as making it that obnoxious to reverse engineer a website, why not stepping it up a notch and obfuscating the JavaScript code in the webpage using file stream side-channel techniques?“.

Reverse-engineering Fujitsu M7MU RELC hardware compression (op-co.de)
This is a follow-up to the Samsung NX mini (M7MU) firmware reverse-engineering series. This part is about the proprietary LZSS compression used for the code sections in the firmware of Samsung NX mini, NX3000/NX3300 and Galaxy K Zoom. The post is documenting the step-by-step discovery process, in order to show how an unknown compression algorithm can be analyzed. The discovery process was supported by Igor Skochinsky and Tedd Sterr, and by writing the ideas out on encode.su.

How to reverse engineer AI models: a study on Google Photos (skyld.io)
Google Photos is one of the most widely-used photo management applications globally, pre-installed on almost every Android device running Google Mobile Services (GMS). It is appreciated by users because it offers powerful features like “Magic Eraser” and advanced AI-powered photo editing tools. Of course, Google doesn’t open-source its AI models to keep its competitive edge.

Using the Linux kernel to help me crack an executable quickly (maowtm.org)
Truth be told, I've never been really good at CTFs, but I do enjoy solving challenges at my own pace, and exploring perhaps less conventional methods, learning more about programming in the process. A few weeks ago I found a reverse engineering problem which basically boiled down to running a Linux binary and entering the correct number to get it to print a flag.

Low cost, high speed data acquisition over HDMI [video] (media.ccc.de)
Through a reverse-engineering effort it is possible to (ab)use a combination of cheap USB 3.2 HDMI video grabbers based on the Macrosilicon MS2130 in combination with small FPGA dev boards like the Sipeed Tang nano series (both ~10 USD each) to capture arbitrary data by connecting them via an HDMI cable. This can be used as a low cost, high speed logic analyzer, ADC capture, DIY SDR etc.

Identifying a defective RAM IC on laptops with soldered memory (piernov.org)
Warning: some information in this article is uncertain and based onto third-party reverse engineering efforts. Official documentation from the memory controller manufacturer is required, however Intel does not make it public. This only shows the idea to narrow down the fault. Additionally, other factors such as a PCB or CPU fault could be the cause and not the RAM ICs themselves (e.g. common failure on MacBook Air 13" 2011 with board number 820-3023).

Reversing C++ Virtual Functions (alschwalm.com)

Breaking AES encrypted firmware using neural networks (fromnothing.blog)
Firmware encryption is becoming a common feature in modern devices. From a security standpoint, that’s welcome news. However, for anyone reverse engineering or testing device security, dumping firmware is often one of the first tasks — and encryption makes that task extremely challenging, if not impossible. So, why are we seeing more encryption? There are several reasons.
