Hacker News with Generative AI: Reverse Engineering

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)
There are a few posts in various parts of the internet discussing reverse engineering C++, and these often address virtual functions to a large or small extent. However, I wanted to take some time to write about dealing with virtual functions in large, ‘enterprisy’ code-bases.

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.

Building an open-source Wi-Fi Mac layer for the ESP32 (esp32-open-mac.be)
The ESP32 is a low-cost microcontroller with Wi-Fi connectivity. Currently, the Wi-Fi MAC layer of the ESP32 is closed-source. This project aims to change that: by reverse engineering the hardware registers and software, we can build a networking stack that is open-source up to the hardware, instead of having to use the proprietary MAC layer.

GoStringUngarbler: Deobfuscating Strings in Garbled Binaries (cloud.google.com)
In our day-to-day work, the FLARE team often encounters malware written in Go that is protected using garble. While recent advancements in Go analysis from tools like IDA Pro have simplified the analysis process, garble presents a set of unique challenges, including stripped binaries, function name mangling, and encrypted strings.
