The people in this community hope for a world where an individual's informational footprints—everything from an opinion on abortion to the medical record of an actual abortion—can be traced only if the individual involved chooses to reveal them; a world where coherent messages shoot around the globe by network and microwave, but intruders and feds trying to pluck them out of the vapor find only gibberish; a world where the tools of prying are transformed into the instruments of privacy. There is only one way this vision will materialize, and that is by widespread use of cryptography. Is this technologically possible? Definitely. The obstacles are political—some of the most powerful forces in government are devoted to the control of these tools. In short, there is a war going on between those who would liberate crypto and those who would suppress it. The seemingly innocuous bunch strewn around this community represents the vanguard of the pro-crypto forces. Though the battleground seems remote, the stakes are not: The outcome of this struggle may determine the amount of freedom our society will grant us in the 21st century. To the Cypherpunks, freedom is an issue worth some risk.

Today we're ecstatic to publish our first demo showing a homemade BusKill Cable (in the prototype 3D-printed case) triggering a lockscreen.

In our last update, I showed a video demo where I successfully triggered a lockscreen using a BusKill prototype without the 3D-printed body for the case and N35 disc magnets. I realized that the N35 disc magnets were not strong enough. In this update, I show a demo with the prototype built inside a 3D-printed case and with (stronger) N42 and N52 cube magnets.

What is BusKill?

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.

If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.

Why?

While we do what we can to allow at-risk folks to purchase BusKill cables anonymously, there is always the risk of interdiction.

We don't consider hologram stickers or tamper-evident tape/crisps/glitter to be sufficient solutions to supply-chain security. Rather, the solution to these attacks is to build open-source, easily inspectable hardware whose integrity can be validated without damaging the device and without sophisticated technology.

Actually, the best way to confirm the integrity of your hardware is to build it yourself. Fortunately, BusKill doesn't have any circuit boards, microcontrollers, or silicon; it's trivial to print your own BusKill cable -- which is essentially a USB extension cable with a magnetic breakaway in the middle

Mitigating interdiction via 3D printing is one of many reasons that Melanie Allen has been diligently working on prototyping a 3D-printable BusKill cable this year. In this article, we hope to showcase her progress and provide you with some OpenSCAD and .stl files you can use to build your own version of the prototype, if you want to help us test and improve the design.

If you'd like to reproduce our experiment and print your own BusKill cable prototype, you can download the stl files and read our instructions here:

Iterate with us!

If you have access to a 3D Printer, you have basic EE experience, or you'd like to help us test our 3D printable BusKill prototype, please let us know. The whole is greater than the sum of its parts, and we're eager to finish-off this 3D printable BusKill prototype to help make this security-critical tool accessible to more people world-wide!

AI summary of transcript:

groundbreaking exploration into transmitting LoRaWAN signals via unconventional means—utilizing microcontrollers lacking native radio functionalities. By tweaking GPIO pins on devices like the CH32V203, ESP32-S2, and ESP8266, OP demonstrates how to generate RF signals strong enough to communicate with commercial LoRaWAN gateways and access the internet. This method deviates from traditional approaches that rely on specific radio chips or RF capabilities. The experiment not only surpasses expectations in terms of signal transmission distance but also showcases a novel blend of ingenuity and technical prowess. Through this project, the resilience and adaptability of LoRa technology are put on full display, proving its capability to facilitate long-range communications under inventive conditions. The venture into RF technology and signal generation through hardware manipulation opens new avenues for utilizing microcontrollers in ways previously deemed impractical, marking a significant achievement in the field.

TETRA vendors caught breaking a basic rule: don't roll your own bespoke cryptographic primitives.

The two discuss the prominent blockchain privacy paper co-authored by Vitalik Buterin, the future of blockchain privacy vs surveillance coins. Alan explains why there’s a need to stop putting the state on a pedestal in the privacy debate in order to defend privacy in the future, the reason the US government doesn’t care as much about money laundering as long as it happens in US banks.

In this talk we will discuss the radio jailbreaking journey that enabled us to perform the first public disclosure and security analysis of the proprietary cryptography used in TETRA (Terrestrial Trunked Radio): a European standard for trunked radio globally used by government agencies, police, prisons, emergency services and military operators. Besides governemental applications, TETRA is also widely deployed in industrial environments such as factory campuses, harbor container terminals and airports, as well as critical infrastructure such as SCADA telecontrol of oil rigs, pipelines, transportation and electric and water utilities. For over two decades, the underlying algorithms have remained secret and bound with restrictive NDAs prohibiting public scrutiny of this highly critical technology. As such, TETRA was one of the last bastions of widely deployed secret proprietary cryptography. We will discuss in detail how we managed to obtain the primitives and remain legally at liberty to publish our findings.
