LUKS Header Shredder (BusKill Self-Destruct Trigger)

This post will describe how to add a trigger that initiates a "self-destruct" sequence when your BusKill laptop kill cord's connection is severed--rendering your data permanently & irrevocably destroyed in the event that your laptop were physically separated from you (ie: by a snach-and-run thief).

LUKS Header Shredder

Many people were disappointed when the original post introducing BusKill only alluded to a self-destruct trigger, without actually describing how to use it with BusKill. This was done for two reasons:

  2. A self-destruct sequence should be taken seriously. Its implementation should be thoroughly thought-out, tested, and forensically analyzed

Rubber Ducky I <3 you; you make hack time lots of fun!

Let's consider a scenario: You're at a public location (let's say a cafe) while necessarily authenticated into some super important service (let's say online banking). But what if--after you've carefully authenticated--someone snatch-and-runs with your laptop?

Maybe you can call your bank to freeze your accounts before they've done significant financial harm. Maybe you can't.

Or maybe your laptop was connected to your work VPN. In less than 60 seconds and with the help of a rubber ducky, the thief could literally cause millions of dollars in damages to your organization.
