Techlore Interview (BusKill, Interdiction, and OpSec)

  1. How to mitigate State-sponsored interdiction attacks,
  2. minimizing attack surfaces of mobile phones with broadband processors,
  3. the threats of AI “identity verification” systems on privacy,

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.

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.

Surely there must be some solution to trigger your computer to lock, shutdown, or self-destruct when it’s physically separated from you! There is: I call it BusKill.
