Created Go bindings for Apple's Hypervisor.framework.

Why? Because I wanted to test a Pure Go emulator I'm writing against and couldn't get unicorn2 to work on macOS 26. Plus what's going to be faster than Apple's OWN hypervisor 😎

Check it out! 🎉

Tutorial: unpacking executables with TinyTracer + PE-sieve In this short blog I would like to demonstrate you how to unpack an executable with PE-sieve and Tiny Tracer. As an example, let’s use the executable that was packed with a modified UPX: 8f66…

The ESP32 "backdoor" that wasn't | Dark Mentor LLC 4 day class covering the full Bluetooth Low Energy (BLE) protocol stack from the bottom (PHY) up to the top (GATT). The core of the class is built around playing with a game application on an Android phone, talking via Bluetooth to an IoT-type piece of hardware, and analyzing the communication between them. The 4th day is focused on assessing a cutomized Ultra-Vulnerable Peripheral firmware, running on Zephyr RTOS, which has had vulnerabilities introduced into it which are representative of vulnerabilities found in the past across many other platforms.

I’ve posted a detailed explanation of why the claimed ESP32 Bluetooth chip “backdoor” is not a backdoor. It’s just a poor security practice, which is found in other Bluetooth chips by vendors like Broadcom, Cypress, and Texas Instruments too. https://darkmentor.com/blog/esp32_non-backdoor/

Great article about Apple's 🍎 Exclaves & Conclaves that provides a high-level overview and then dives into technical details implemented in XNU 👀

THIS IS HUGE! Researchers at Stanford University have developed a dual-antibody treatment that remains effective against ALL SARS-CoV-2 variants by targeting a less-mutable part of the virus. This breakthrough could lead to longer-lasting therapies that OUTPACE viral evolution. 🧪🧵⬇️

Undocumented commands found in Bluetooth chip used by a billion devices The ubiquitous ESP32 microchip made by Chinese manufacturer Espressif and used by over 1 billion units as of 2023 contains undocumented commands that could be leveraged for attacks.

Tarlogic found a "backdoor" im the ESP32 chips:

Broadcom & Cypress chips have the same HCI "backdoor" allowing to write to the Bluetooth chip's RAM. This feature is used for firmware patches.

“From One Thousand Pages of Specification to Unveiling Hidden Bugs: Large Language Model Assisted Fuzzing of Matter IoT Devices”

With a focus on the Matter network protocol, walks through the process of using an LLM to transform a human-readable spec into something a fuzzer can leverage.

Hello new (fuzzing) followers! I haven’t done much fuzzing recently unfortunately but here’s an example of past work I’m happy to talk about: mhlakhani.com/static/pdf/F...

Still hope to get back to it one day. But for now I’m still in the security / systems space (and dabbling in AI)

GitHub - microsoft/markitdown: Python tool for converting files and office documents to Markdown. Python tool for converting files and office documents to Markdown. - microsoft/markitdown

Microsoft just released a tool that lets you convert Office files to Markdown. Never thought I'd see the day.

Google also added Markdown export to Google Docs a few months ago.

sdk.blue A curated list of libraries & SDKs for the Bluesky API and AT Protocol

I'm launching a new website: sdk.blue - a list of all libraries/SDKs for building things on #ATProto, grouped by language 🙂

If I forgot anything important, or you have an ATProto/Bluesky library that you think would be a good fit there (or if I should remove anything), please send me a PR :) #atdev

LIEF Disassembler API based on LLVM MC

So for my first post on Bluesky, I'm happy to share that LIEF (extended) is now providing an API to disassemble code (backed by the LLVM MC layer).

This disassembler is integrated with other functionalities
like dyldsc or DWARF info.

You can checkout lief.re/doc/latest/e... for the details.
