BusKill Release Announcement v0.7.0

Most importantly, this release allows you to arm the BusKill GUI app such that it shuts-down your computer when the BusKill cable’s connection to the computer is severed.

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.

Upgrading

You can upgrade your BusKill app to the latest version either by

  1. Clicking “Update” in the app or
  2. Downloading it from GitHub

Changes

This update includes many bug fixes and new features, including:

  1. Adds support for ‘soft-shutdown’ trigger to GUI
  2. Adds a new buskill.ini config file
  3. Adds a new “Settings” screen in GUI
  4. Merges kivy & buskill config files into one standardized location
  5. Fixes in-app updates on MacOS
  6. Fixes lockscreen trigger on Linux Mint Cinnamon

Documentation Improvements

We’ve also made many improvements to our documentation

  1. Updated the Software User Guide to include how to arm the BusKill app with the soft-shutdown trigger in the GUI
  2. Added a manpage
  3. Better documentation on how to build your own USB-C BusKill Cable
  4. Better documentation on how to test the buskill app
  5. Fixes in Release Workflow
  6. Added some additional related projects to our documentation

Soft-Shutdown Trigger

This release now allows you to choose between either [a] locking your screen or [b] shutting down your computer when you arm the BusKill app from the GUI. By default, the BusKill app will trigger the lockscreen. To choose the ‘soft-shutdown’ trigger, open the navigation drawer, go to the Settings Screen, click Trigger, and change the selected trigger from lock-screen to soft-shutdown. For more information, see our Software GUI User Guide.

BusKill Now in Debian!

We’re also happy to announce that, with the release of Debian 12, it’s now possible to install BusKill in Debian with Apt!

sudo apt-get install buskill

Testers Needed!

We do our best to test the BusKill app on Linux, Windows, and MacOS. But unfortunately it’s possible that our app doesn’t fully function on all versions, distributions, and flavours of these three platforms.

We could really use your help testing the BusKill app, especially if you have access to a system that’s not (yet) listed in our Supported Platforms.

And in this release, we specifically would like you to help us test the new soft shutdown feature. Please let us know if it does or does not work for you.

Please contact us if you’d like to help test the BusKill app :)

    Definitely. I assume the actual cost for the cable is <10$, but engineering work gets very expensive very fast if you’re small scale.

    I’m interested in something - say you got an order for 1 million units, what’s the price per unit you could offer?

    Edit: just looked at the DIY option - seems right now you’re just using off the shelf parts, which is fine. Clever use of them, even. Main part seems to be ‘present usb device - once the usb device gets removed, lock down the PC’. So, you specifically just need some usb device with a cord that attaches magnetically - and securely enough that it doesn’t disconnect randomly, with some mechanical way to fix it to yourself. So yeah, at million scale, seems you could definitely sell it for 10 bucks a piece.

      I’ve paid myself nothing so-far. The price just barely breaks-even for the business. There’s one-time costs like a few grand for a CNC’d injection mold and assembly jig, but also certification fees, product boxes, cardstock paper for documentation inserts, printing fees, artist commissions, packaging materials, warehousing, shipping, other logistics fees, etc.

      All of this is explained in-detail in “The Finances” section here.

      I prefer open-source hardware to be designed using common off-the-shelf items that are easily found everywhere in the world. Unfortunately, the one vendor of a USB-A magnetic breakaway couplers decided to EOL their product shortly after I published a guide on how to build your own BusKill cable. After we published, they all got sold-out, and we had to go to manufacturers for a custom component.

      Prices would drop dramatically if we could do production runs (and actually sell) >10,000 units at a time. Currently we only sell a few cables per month. If you want to help, please tell all your security-conscious friends about BusKill :)
