Problem: Need offline/cold storage for our coins
Solution: AMD-based HP CloudBook laptop at Target for $180
Why AMD? Many Intel CPUs have vPro techology baked in – which has a nasty security hole allowing remote IP KVM to be enabled, allowing for keystroke logging that is simply unacceptable on our wallet machine.
They come with Windows 10 Home preinstalled, which we go ahead and log into and download the following things:
Opera Browser: http://opera.com
Install the opera browser, go into settings and turn on VPN in the Privacy and Security section
Xubuntu ISO image:
http://torrent.ubuntu.com/xubuntu/releases/xenial/release/desktop/xubuntu-16.04.3-desktop-amd64.iso.torrent
Rufus USB image writer: https://rufus.akeo.ie
Run rufus after downloading, select the Xubuntu ISO image you downloaded before rufus and write it to a 4GB-32GB USB stick (preferably a USB 3.0 one)
Reboot and keep tapping Esc to go into the BIOS
Find the boot order, move USB devices above the built-in SSD in the boot order and reboot.
Install Xubuntu, enabling disk and LVM encryption when you get to that point in the install. Pick a password you will not forget.
Once Xubuntu is installed and you are logged in, connect to the internet, open a terminal and do the following to bring the system up to date:
sudo apt-get update
sudo apt-get upgrade -y
reboot
sudo apt-get autoremove
Go through the power settings and enable suspend on lid close and shutdown on reaching critical battery levels.
Firefox is installed already, use it to download and install Opera. I have had better luck downloading the file and installing it in the terminal rather than using the GUI software manager. The command to install manually is:
sudo dpkg -i <packagename>.deb
You will find it in your /home/<username>/Downloads folder
And that’s how we turned a $180 cloudbook into a whole-disk-encrypted hardware eCoin wallet.
