Finally got a Tesla Model 3 — well, technically it’s running in QEMU.

Tesla and SpaceX/Starlink security architectures look almost identical: • Hardware Root of Trust (ROM + eFUSE) • Multi-stage secure boot • dm-verity / runtime integrity • Debug interfaces permanently fused off • Explicit physical-access threat model Not shared code — shared engineering philosophy. Both accept that physical attacks can succeed, then focus on making them expensive and limiting post-root impact. That’s why voltage fault injection works on both.
Based on the talks presented at the hacker conferences, it’s not hard to see that the security designs and approaches used in Elon Musk’s two companies, SpaceX and Tesla, are remarkably similar. Fault injection attacks can likewise be used to break the secure boot mechanisms of both products and ultimately obtain root access.

A year and a half ago, I took on the 5G flagship phone signal testing project for Geekerwan. Honestly, handling such a huge volume of test cases single-handedly was a serious challenge. At the time, they didn't have the supporting hardware infrastructure in place, so most things basically had to be built up from scratch, step by step. I spent nearly half a year there fiddling with all kinds of phones from various brands and models—to the point that for a long stretch afterward, just seeing a phone made my head ache and turned my stomach. piped.video/BsOlDCx0E4I?is=6X8b…

Fault injection attacks can likewise be used to break the secure boot mechanisms of both products and ultimately obtain root access.
The voltage glitch described in my previous post works by briefly reducing core voltage so that a clocked instruction does not complete correctly. In the example, the target is the conditional branch that enforces the failed signature check (`B lock_down`). A short pulse on the MOSFET can cause the instruction decoder to fail to resolve the opcode, so the processor advances past that instruction. Pulse widths on the order of tens of nanoseconds are within the range used in published attacks. In practice the outcome depends on exact timing relative to the clock edge, the depth of the voltage drop, and the state of the power delivery network. Most attempts produce a reset or no change in control flow. The usable parameter window (offset and width) is usually found by automated scanning rather than a single correctly timed pulse. Many secure-boot implementations add countermeasures that reduce the probability of a successful fault: brown-out detectors, voltage monitors, redundant checks, or randomized delays before the critical instruction. These do not remove the underlying sensitivity of CMOS logic to supply voltage, but they increase the number of attempts required and the precision needed. The technique therefore remains a physical attack on the enforcement of the security check rather than on the cryptographic verification itself.

I put together a website showcasing these tools and what they do. sistudiohq.com
Over the past year or so, I've been heavily using AI for development and reverse-engineering, and in my spare time I've built several practical tools that I frequently use: 1Claude Code Monitor: Monitor & audit every action Claude Code takes on your computer. cc-monitor.com 2IoT Firmware Deep Analysis: Automated reverse engineering and vulnerability discovery for IoT firmware binaries. ifda.dev 3BeeEye (seems like Wireshark on the web) beeeye.dev 4PaperInsight: Focused on PDF translation and AI interpretation of PDF research papers. paper-insight.com 5AI Code Analyzer github.com/cn0xroot/AI-Code-…: An AI large-model-based code analysis system that automatically generates project function overviews, technology stack analysis, architecture design, implementation principles, and outputs Mermaid visualizations (architecture diagrams, flowcharts, class diagrams, sequence diagrams, etc.). All of the tools listed above were developed because I found them personally useful, and I built them in my spare time. To date, I've continued to improve and refine them purely out of passion and interest—these tools haven't generated any revenue or financial return yet.

Looks really cool! I’m curious whether you can use eBPF on the actual vehicle. If so, using ArgusBPF github.com/cn0xroot/ArgusBPF could be really interesting. A real car would probably expose a lot more interesting things to explore than QEMU. piped.video/0IaR9INcCyo?is=-vIg…
They said I couldn’t run custom apps in a Tesla. I proved them wrong. I can, and I will. And no, it’s not going to be a click counter 😈 Want to install third-party apps in yours too? Something big is coming. @CoilShift

Turned a WiFi 7 router into a 320Msps SDR. Custom firmware on its MediaTek MT7996 streams raw 14-bit IQ from 2.4/5/6GHz over 10GbE without dropping samples. It's not a snapshot mode, the waterfall is just one thing reading the stream. github.com/h0m3us3r/w1700k-s…

It looks like they adapted the NB-IoT frequency bands for different countries and regions, in order to ensure connectivity to the local cellular network no matter where the device is.
Replying to @0xJohannes_
The antenna reads "欧亚版 (Ōuyà bǎn)", meaning "Eurasian version", so there could be more out there. I'm guessing they had to make different versions depending on the available LTE frequencies in each region.

Some speculation: these people may have initially tried to extract the private key from the chip via a side-channel attack, but ultimately found it unworkable—so they switched to a scheme that reads the information displayed on screen in order to steal and exfiltrate the key. To save power, the 4G communication here should differ from a phone's 4G—my guess is it's using NB-IoT.
My spy-implanted ledger came from Malaysia, and had flawless shrink wrap. Even opening it, at first you don't see the implant which is cleverly hidden where the screen's padding is supposed to be. Follow Ledger's guidance to check yours: support.ledger.com/article/4…

By the way: if a sample of this hardware wallet device were available, besides extracting and reverse-engineering the firmware, you could also use an Amarisoft 4G setup inside a Faraday cage with NB-IoT mode enabled (with 4G authentication turned off) to draw the hardware wallet into connecting to it—thereby capturing the device's 4G traffic and obtaining the backend/backdoor server's address information.
