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:

  1. Most people probably don’t actually want an accidental false-positive to destroy all their data and
     
  2. A self-destruct sequence should be taken seriously. Its implementation should be thoroughly thought-out, tested, and forensically analyzed

This article will provide that thorough analysis and explain to the reader how to implement a self-destruct trigger with BusKill on linux machines that have FDE with LUKS.

BusKill Onion Service

Today, we’re happpy to announce that there’s a new way to browse our website more securely and anonymously. To do it, you’ll need a bit of software called the Tor Browser

After the Tor Browser is installed, copy and paste this URL into the address bar to load this website:

buskillvampfih2iucxhit3qp36i2zzql3u6pmkeafvlxs3tlmot5yad.onion


buskillvamp fih2iucxhit
3qp36i2zzql 3u6pmkeafvl
xs3tlmot5ya     d.onion

Besides the obvious anonymity benefits–allowing our customers to purchase our products anonymously–we chose to make our website accessible at the above .onion address to take advantage of tor’s superior Public Key Infrastructure to the clearnet’s flawed x509 model (read: it’s more secure).

Visit this site now on our tor .onion address

Instead of using the untrustworthy X.509 PKI model, all connections to a v3 .onion address is made to a single pinned certificate that is directly correlated to the domain itself (the domain is just a hash of the public key + some metadata). Moreover, some of the most secure operating systems send all the user’s Internet traffic through the Tor network — for the ultimate data security & privacy of its users.

In short, users are much safer when communicating directly to a website using a .onion domain than its clearnet domain.

We’ve always made sure that our site’s content was fully accessible to Tor Browser on strict mode. Unlike other popular websites, we would never use Google reCAPTCHA or blanket block Tor exit nodes.

We want and encourage our customers to be able to use all of our services over Tor. And by adding our service over an Onion Service, our customers with a healthy distrust for the X.509 PKI can take comfort in knowing that accessing our website through our Onion Service address will give them end-to-end encryption using our Tor-generated certificate.

Introducing BusKill: A Kill Cord for your Laptop

This post will introduce a simple udev rule and ~$20 in USB hardware that effectively implements a kill cord Dead Man Switch to trigger your machine to self-destruct in the event that you’re kicked out of the helm position.

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.
