Official(ish) deep dark onion code::j0rg3 mirror

Recently I decided that I wanted my blog to be available inside of the Deep, Dark Onion (Tor).

First time around, I set up a proxy that I modified to access only the clear web version of the blog and to avail that inside Tor as a ‘hidden service’.

My blog is hosted on equipment provided by the kind folk at insomnia247.nl and I found that, within a week or so, the address of my proxy was blocked. It’s safe for us to assume that it was simply because of the outrageous popularity it received inside Tor.

By “safe for us to assume” I mean that it is highly probable that no significant harm would come from making that assumption. It would not be a correct assumption, though.

What’s more true is that within Tor things are pretty durn anonymous. Your logs will show Tor traffic coming from 127.0.0.1 only. This is a great situation for parties that would like to scan sites repeatedly looking for vulnerabilities — because you can’t block them. They can scan your site over and over and over. And the more features you have (e.g., comments, searches, any form of user input), the more attack vectors are plausible.

So why not scan endlessly? They do. Every minute of every hour.

Since insomnia247 is a provider of free shells, it is incredibly reasonable that they don’t want to take the hit for that volume of traffic. They’re providing this service to untold numbers of other users, blogs and projects.

For that reason, I decided to set up a dedicated mirror.

Works like this: my blog lives here. I have a machine at home which uses rsync to make a local copy of this blog. Immediately thereafter it rsyncs any newly gotten data up to the mirror in onionland.

After consideration, I realized that this was also a better choice just in case there is something exploitable in my blog. Instead of even risking the possibility that an attacker could get access to insomnia247, they can only get to my completely disposable VPS which has hardly anything on it except this blog and a few scripts to which I’ve already opened the source code.

I’ve not finished combing through but I’ve taken efforts to ensure it doesn’t link back to clear web. To be clear, there’s nothing inherently wrong with that. Tor users will only appear as the IP address of their exit node and should still remain anonymous. To me, it’s just onion etiquette. You let the end-user decide when they want to step outside.

To that end, the Tor mirror does not have the buttons to share to Facebook, Twitter, LinkedIn, Google Plus.

That being said, if you’re a lurker of those Internet back-alleys then you can find the mirror at: http://aacnshdurq6ihmcs.onion

Happy hacking, friends!

Installing INN’s Project Largo in a Docker containter

Prereqruisites: Docker, Git, SSHFS.

Today we’re going to look at using Docker to create a WordPress installation with the Project Largo parent theme and a child theme stub for us to play with.

Hart Hoover has established an image for getting a WordPress installation up and running using Docker. For whatever reason, it didn’t work for me out-of-box but we’re going to use his work to get started.

Let’s make a place to work and move into that directory:
cd ~
mkdir project.largo.wordpress.docker
cd project.largo.wordpress.docker

We’ll clone the Docker/Wordpress project. For me, it couldn’t untar the latest WordPress. So we’ll download it outside the container, untar it and modify the Dockerfile to simply pull in a copy:
git clone https://github.com/hhoover/docker-wordpress.git
cd docker-wordpress/
ME=$(whoami)
wget http://wordpress.org/latest.tar.gz
tar xvf latest.tar.gz
sed -i 's/ADD http:\/\/wordpress.org\/latest.tar.gz \/wordpress.tar.gz/ADD \.\/wordpress \/wordpress/' Dockerfile
sed -i '/RUN tar xvzf \/wordpress\.tar\.gz/d' Dockerfile

Then, build the project which may take some time.
sudo docker build -t $ME/wordpress .

If you’ve not the images ready for Docker, the process should begin with something like:
Step 0 : FROM boxcar/raring
Pulling repository boxcar/raring
32737f8072d0: Downloading [> ] 2.228 MB/149.7 MB 12m29s

And end something like:
Step 20 : CMD ["/bin/bash", "/start.sh"]
---> Running in db53e215e2fc
---> 3f3f6489c700
Successfully built 3f3f6489c700

Once the project is built, we will start it and forward ports from the container to the host system, so that the Docker container’s site can be accessed through port 8000 of the host system. So, if you want to see it from the computer that you’ve installed it on, you could go to ‘HTTP://127.0.0.1:8000’. Alternatively, if your host system is already running a webserver, we could use SSHFS to mount the container’s files within the web-space of the host system.

In this example, however, we’ll just forward the ports and mount the project locally (using SSHFS) so we can easily edit the files perhaps using a graphical IDE such as NetBeans or Eclipse.

Okay, time to start our Docker image and find its IP address (so we can mount its files):
DID=$(docker run -p 8000:80 -d $ME/wordpress)
DIP=$(docker inspect $DID | grep IPAddress | cut -d '"' -f 4)
docker logs $DID| grep 'ssh user password:' --color

Copy the SSH password and we will make a local directory to access the WordPress installation of our containter.
cd ~
mkdir largo.mount.from.docker.container
sshfs user@$DIP:/var/www $HOME/largo.mount.from.docker.container
cd largo.mount.from.docker.container
PROJECT=$(pwd -P)

Now, we can visit the WordPress installation and finish setting up. From the host machine, it should be ‘HTTP://127.0.0.1:8000’. There you can configure Title, Username, Password, et cet. and finish installing WordPress.

Now, let’s get us some Largo! Since this is a test project, we’ll sacrifice security to make things easy. Our Docker WordPress site isn’t ready for us to easily install the Largo parent theme, so we’ll make the web directory writable by everybody. Generally, this is not a practice I would condone. It’s okay while we’re experimenting but permissions are very important on live systems!

Lastly, we’ll download and install Largo and the Largo child theme stub.
ssh user@$DIP 'sudo chmod -R 777 /var/www'
wget https://github.com/INN/Largo/archive/master.zip -O $PROJECT/wp-content/themes/largo.zip
unzip $PROJECT/wp-content/themes/largo.zip -d $PROJECT/wp-content/themes/
mv $PROJECT/wp-content/themes/Largo-master $PROJECT/wp-content/themes/largo
wget http://largoproject.wpengine.netdna-cdn.com/wp-content/uploads/2012/08/largo-child.zip -O $PROJECT/wp-content/themes/largo-child.zip
unzip $PROJECT/wp-content/themes/largo-child.zip -d $PROJECT/wp-content/themes
rm -rf $PROJECT/wp-content/themes/__MACOSX/

We are now ready to customize our Project Largo child theme!

Making ixquick your default search engine

In this writer’s opinion, it is vitally important that we take reasonable measures now to help insure anonymity, lest we create a situation where privacy no longer exists, and the simple want of, becomes suspicious.

Here’s how to configure your browser to automatically use a search engine that respects your privacy.

Chrome:

  1. Click Settings.
  2. Click “Set pages” in the “On startup” section.
  3. Enter https://ixquick.com/eng/ in the “Add a new page” text field.
  4. Click OK.
  5. Click “Manage search engines…”
  6. At the bottom of the “Search Engines” dialog, click in the “Add a new search engine” field.
  7. Enter
    ixquick
    ixquick.com
    https://ixquick.com/do/search?lui=english&language=english&cat=web&query=%s
  8. Click “Make Default”.
  9. Click “Done”.

Firefox:

  1. Click the Tools Menu.
  2. Click Options.
  3. Click the General tab.
  4. In “When Firefox Starts” dropdown, select “Show my home page”.
  5. Enter https://ixquick.com/eng/ in the “Home Page” text field.
  6. Click one of the English options here.
  7. Check box for “Start using it right away.”
  8. Click “Add”.

Opera:

  1. Click “Manage Search Engines
  2. Click “Add”
  3. Enter
    Name: ixquick
    Keyword: x
    Address: https://ixquick.com/do/search?lui=english&language=english&cat=web&query=%s
  4. Check “Use as default search engine”
  5. Click “OK”

Internet Explorer:

      _     ___  _ __        ___   _ _____ ___ 
     | |   / _ \| |\ \      / / | | |_   _|__ \
     | |  | | | | | \ \ /\ / /| | | | | |   / /
     | |__| |_| | |__\ V  V / | |_| | | |  |_| 
     |_____\___/|_____\_/\_/   \___/  |_|  (_) 
    
    
    (This is not a good strategy for privacy.)

Congratulations!

\o/

You are now one step closer to not having every motion on the Internet recorded.

This is a relatively small measure, though. You can improve your resistance to prying eyes (e.g., browser fingerprinting) by using the Torbrowser Bundle, or even better, Tails, and routing your web usage through Tor, i2p, or FreeNet.

If you would like more on subjects like anonymyzing, privacy and security then drop me a line via email or Bitmessage me: BM-2D9tDkYEJSTnEkGDKf7xYA5rUj2ihETxVR

Debugging PHP with Xdebug

I have finished (more-or-less) making a demo for the Xdebug togglin’ add-on/extension that I’ve developed.

One hundred percent of the feedback about this project has been from Chrome users. Therefore, the Chrome extension has advanced with the new features (v2.0), allowing selective en/dis-ableing portions of Xdebug’s output. That is you can set Xdebug to firehose mode (spitting out everything) and then squelch anything not immediately needed at the browser layer. The other information remains present, hidden in the background, available if you decide that you need to have a look.

The Firefox version is still at v1.2 but will be brought up to speed as time permits.

If you want that firehose mode for Xdebug, here’s a sample of some settings for your configuration ‘.ini’ file.

The demo is here.
