Useful to protect your cryptocurrency from theft as the BusKill laptop kill cord will lock, shutdown, or wipe your encryption keys if your laptop is physically taken from you

BusKill does not ship with destructive triggers.

The current app is limited to locking your screen. Future releases will include soft/hard shutdown. So, by default, your clumsiness would just mean you have to type your password to unlock your screen. Not a big compromise :)

We do have a "LUKS Header Shredder" trigger (which we call self-destruct as it renders all the data on the FDE disk useless), but we (intentionally) don't include it by default and raise the barrier of entry because of the risk of data loss.

We'll be publishing a more detailed write-up on the LUKS Header Shredder in 2 weeks. You can subscribe for updates on our website (buskill.in) or the campaign directly (crowdsupply.com)

All orders are handled by CrowdSupply (via Mouser). They handle shipping, VAT, import taxes, etc.

It certainly added cost to the final product, but I figured it was more fair & transparent to everyone to set shipping to $0 internationally (I hate it when you finally make it to payment and only then learn shipping is $20 :/).

Ah, crap, sorry about that.

I'll try to remember to update the verbiage of that lower line to reference the top line to prevent this from happening again in the future.

Thanks for pointing it out!

Hi, Michael Altfield here (Founder of the BusKill project and holder of the PGP Key for signing canaries)

No, you should not be concerned. The latest canary #002 literally says:

  Period: 2021-06-01 to 2021-12-31
  Expiry: 2022-01-31
Source: https://www.buskill.in/canary-002/

What matters is what's cryptographically signed. Did I make a mistake somewhere else?

The next canary will be posted before 2022-01-31.

If all you want is a bluetooth/wifi solution, then there's tons of "solutions" on the market for this. See our "comparison" table on CrowdSupply for some options:

When I designed BusKill, I intentionally avoided wireless solutions.

BusKill is designed for situations where the risk is extremely high, and you'll find that the radio-based solutions aren't very secure. They're faulty and have huge surface areas of attack.

Yes! That was just under 2 years ago. It's the same project.

DIY is great. The problem is that after I published that article, everyone on Hacker News went and bought-out all the USB-A magnetic breakways on Amazon. And they literally never re-stocked (I found out later it was EOL from the manufacture).

The reason I launched this crowdfunding campaign was to put these USB-A magnetic breakaway cables back on the market so people could build their own again (and to sell the whole kit, to lower the barrier of entry to non-techie journalists).
