Install mitmproxy

Follow the instructions to install mitmproxy and launch either mitmproxy or mitmweb. If you plan on sniffing traffic from a macOS VM, it is probably preferable to install mitmproxy on the host OS.
Change your proxy settings in macOS to use your local IPv4 address with port 8080 (by default).
- System Settings → Network → Advanced → HTTP and HTTPS proxies
Install the mitmproxy certificate by navigating to http://mitm.it/
Disable SSL verification.
- On mitmweb, this is toggled in Options → Don't verify server certificates

GSoC 2020 | Virtual U2F security key

This summer, I had the opportunity to participate in the GSoC 2020 program within the QEMU organization on a project that interested me a lot.

The subject was 'Virtual U2F security key', and now that the GSoC is almost finished, it's time for me to summarize this project I worked on.

These instructions will take you through the step by step process of building and flashing a custom build of the Coreboot ROM to a Chromebook C201.

This guide expects you to have a Chromebook C201, and another ARM computer with Ubuntu installed. Specifically I used the Odroid XU2. You may be able to do this on an Intel platform, using a cross compiler. See the sidenotes section for more information.

Setting up your Ubuntu

Install dependancies

Update your Ubuntu aptitude and install the dependancies we will need.

Basic conversion

# raspbian stretch lite on ubuntu

### You can write the raspbian image onto the sd card,
# boot the pi so it expands the fs, then plug back to your laptop/desktop
# and chroot to it with my script 
# https://gist.github.com/htruong/7df502fb60268eeee5bca21ef3e436eb
# sudo ./chroot-to-pi.sh /dev/sdb
# I found it to be much less of a pain in the ass and more reliable
# than doing the kpartx thing

On my Macbook Pro (OS X El Capitan) I was having issues on Electron based apps. These apps had visual issues/glitches like blank screens, visual components showing only when hovering or transparent menus.

By opening with these comands, the problems disappeared.
