We’re happy to announce that you can now purchase USB Type-C BusKill cables.
One of the most common requests from our customers since we started shipping BusKill cables 4 years ago has been for a cable that can be plugged directly into a computer with USB-C ports (without a USB-A to USB-C adapter).
We’re super happy to share that Techlore invited BusKill founder Michael Altfield onto their YouTube channel to talk about BusKill, security, and privacy
In addition to answering questions about the origin of BusKill, the interview ran a gamut of issues regarding security and privacy — including
How to mitigate State-sponsored interdiction attacks,
minimizing attack surfaces of mobile phones with broadband processors,
the threats of AI “identity verification” systems on privacy,
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.
If you want to help our open-source project, please consider purchasing a BusKill cable for yourself or a loved one. It helps us fund further development, and you get your own BusKill cable to keep you or your loved ones safe.
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.
In our last update, I showed a video demo where I succesfully 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.

A few years ago, Michael asked me if I was interested in developing a 3D-printed case for the magnetic breakaway. He enumerated the following design requirements:
The case should be as small as possible, because it shouldn’t block neighboring ports, nor sit heavy in the port causing it to bump into objects on the desk.
The case should be able to be dissembled, so that people can make sure it isn’t tampered with. It shouldn’t be glued together.
In order to avoid using glue, we had a factory specially manufacture some hexagonal shaped magnets that we believed would be able to sit inside the printed part without glue.
Much like USB breakaways that are designed to prevent wear and tear on ports, the case would house a pogo pins and magnets, and a USB.

However, over the past years’ iterations, we adjusted the requirements:
