BusKill

The USB kill cord for your laptop

This project is coming soon. Sign up to receive updates and be notified when this project launches.


BusKill is the world’s first laptop kill cord, a hardware "dead man’s switch" that executes a user-configurable trigger when your machine is physically separated from you. BusKill can protect the data stored on your (encrypted) device and any accounts that you’re currently logged into from the worst case scenario of a snatch-and-run thief. It is designed to be easy-to-use on Linux, Windows 10, and MacOS. The GUI app currently supports the ability to trigger a lockscreen on all three platforms. Even better, we’ll soon be releasing built-in triggers to shutdown the computer when the cable disconnects.

Advanced Linux users can manually add auxiliary triggers, such as a self-destruct trigger that wipes the LUKS header, making the entire disk permanently inaccessible (even to rubber-hose cryptanalysis). Note that this is an advanced feature that is intentionally inaccessible upon startup. BusKill will, of course, not ship with any destructive triggers!

A Lifesaver for Tourists, Journalists, Activists and More

BusKill is useful in a wide variety of situations.

Primarily, BusKill can help journalists operating in oppressive regime keep their documents and their sources safe when the political police suddenly raid their workplace.

BusKill can also protect a tourist’s important accounts from a snatch-and-run laptop thief when logged-in, or keep an activist’s affinity group safe when the secret police suddenly raid an organizer’s home.

It can protect the private keys stored on a crypto trader’s machine while trading OTC or on an exchange, and generally prevent an unlocked computer from ending-up in any competitor’s hands.

And BusKill can be a lifesaver for intelligence operatives.

  • Hardware kill cable is simpler and less vulnerable to attacks (compared to radio-based solutions)
  • Strong N52 neodymium magnets reduce false-positives

Incredibly Simple to Use

1. Attach BusKill cord to your belt loop, or another secure attachment point (we suggest on your person).
