Privacy Part II: VPN/IPVanish - Install IPVanish on Kali Linux

Okay, so you’re running Whonix, Tails or, at least, TorBrowser.

What’s next? You may wish to consider using a VPN. In simple terms, it’s somewhat similar to what Tor offers. That is: you connect to the VPN and your connection passes through them such that the site that you are visiting will see the VPN’s IP address rather than yours. Of course, that means that you can chain them.

That is: (You)->VPN->Tor->Exit node->Web site

The reason that you might feel compelled to take this step is that a party which is able to see your traffic into and out of Tor could still identify you. The thinking is that the parties who wish to interfere with your privacy could be compelled to run Tor bridges, relays and exit nodes. If traffic from your IP address could be matched to requests coming from the Tor exit node then you could, effectively, be identified.

Some people hold that using a VPN to access Tor does not improve your anonymousness. I am not among them. In particular, you will find that IPVanish offers VPN service for under $7 per month and is popular among users of the Tor network. Which means that in addition to the fact that IPVanish is not logging your traffic, there’s an excellent chance that other users are going from IPVanish into Tor, helping to reduce the uniqueness of your traffic.

By the way, I’d suggest poking around the web a little bit. While their prices are already great you can find some even deeper discounts: https://signup.ipvanish.com/?aff=vpnfan-promo

IPVanish’s site offers instructions for installing the VPN in Ubuntu so we’re going to take a look at using IPVanish in Kali — including an interesting and unanticipated snag (and, of course, how to fix it).

Let’s grab the OpenVPN configuration:
wget http://www.ipvanish.com/software/configs/ca.ipvanish.com.crt; wget http://www.ipvanish.com/software/configs/ipvanish-US-New-York-nyc-a01.ovpn

We will need the OpenVPN package for Gnome:
apt install network-manager-openvpn-gnome

Click on the tray in the upper right corner, then the wrench/screwdriver icon:

Select the ‘Network’ folder icon:

We’re choosing ‘Wired’ (even though we’re using wlan0 interface):

We’re setting up a VPN, of course:

Import from file:

Choose the configuration file that we downloaded previously:

Enter ‘User name’ and ‘Password’:

We are connected!

Verified at IPVanish’s site: https://www.ipvanish.com/checkIP.php

And this is where I had anticipated the installation instructions would end.

I just wanted to check a few more things. And I would love to tell you that it was simply my thoroughness and unbridled CLI-fu that led to discover that I was still making ipv6 connections outside of the VPN. Seems that it wasn’t noticed by the test at IPVanish because they deal only in ipv4. I was able to prove my ipv6 address and geolocation by using: http://whatismyipaddress.com/

Further, we can establish that the test at IPVanish is not ipv6-compatible with a quick test.

The easy fix here is to disable ipv6 locally. It is plausible that this could cause unintended consequences and, to be thorough, it would be best to handle your VPN at the firewall. Having support for OpenVPN, you’ll be able to get this running with a huge variety of routing/firewall solutions. You can grab any number of tiny computers and build a professional-quality firewall solution with something like pfSense. Maybe we’ll take a look at getting that configured in a future post.

But, for now, let’s shut down ipv6 in a way that doesn’t involve any grandiose hand-waving magic (i.e., unexplained commands which probably should work) and then test to get confidence in our results.

Let’s use sysctl to find our ipv6 kernel bits and turn them off. Then we’ll load our configuration changes. As a safety, it wouldn’t be a bad idea to look in /etc/sysctl.conf to verify that there aren’t any ipv6 configs in there.

We’ll back up our config file then turn off everything ipv6 by listing everything with the words ‘ipv6’ and ‘disable’:
cp /etc/sysctl.conf /etc/$(date +%Y-%m-%d.%H-%M-%S).sysctl.conf.bak && \
sysctl -a | grep -i ipv6 | grep disable | sed 's/0/1/g' >> /etc/sysctl.conf && \
sysctl -p

To explain what we’re doing:
List all kernel flags; show uonly those containing the string ‘ipv6’; of those that remain, show only those that contain the string ‘disable’:
sysctl -a | grep -i ipv6 | grep disable
Replace the 0 values with 1, to turn ON the disabling, by piping output to:
sed 's/0/1/g'
That all gets stuck on the end of ‘sysctl.conf’ by redirecting stdout to append to the end of that file:
>> /etc/sysctl.conf
Then we reload with:
sysctl -p

Then as a final sanity-check we’ll make sure we can’t find any ipv6 packets sneaking about:
tcpdump -t -n -i wlan0 -s 256 -vv ip6

At this point, assuming our tcpdump doesn’t show any traffic, we should be ipv6-free with all of our ipv4 traffic shipped-off nicely through IPVanish!

The making of a Docker: Part I - Bitmessage GUI with SSH X forwarding

Lately, I’ve been doing a lot of work from a laptop running Kali. Engaged in pursuit of a new job, I’m brushing up on some old tools and skills, exploring some bits that have changed.

My primary desktop rig is currently running Arch because I love the fine grain control and the aggressive releases. Over the years, I’ve Gentoo’d and Slacked, Crunchbanged, BSD’d, Solarised, et cet. And I’ve a fondness for all of them, especially the security-minded focus of OpenBSD. But, these days we’re usually on Arch or Kali. Initially, I went with Black Arch on the laptop but I felt the things and ways I was fixing things were too specific to my situation to be good material for posts.

Anyway, I wanted to get Bitmessage running, corresponding to another post I have in drafts. On Kali, it wasn’t going well so I put it on the Arch box and just ran it over the network. A reasonable solution if you’re in my house but also the sort of solution that will keep a hacker up at night.

If you’re lucky, there’s someone maintaining a package for the piece of software that you want to run. However, that’s often not the case.

If I correctly recall, to “fix” the problem with Bitmessage on Kali would’ve required the manual installation an older version of libraries that were already present. Those libraries should, in fact, be all ebony and ivory, living together in harmony. However, I just didn’t love the idea of that solution. I wanted to find an approach that would be useful on a broader scale.

Enter containerization/virtualization!

Wanting the lightest solution, I quickly went to Docker and realized something. I have not before built a Docker container for a GUI application. And Bitmessage’s CLI/daemon mode doesn’t provide the fluid UX that I wanted. Well, the easy way to get a GUI out of a Docker container is to forward DISPLAY as an evironment variable (i.e., docker run -e DISPLAY=$DISPLAY). Splendid!

Except that it doesn’t work on current Kali which is using QT4. There’s a when graphical apps are run as root and though it is fixed in QT5, we are using current Kali. And that means we are, by default, uid 0 and QT4.

I saw a bunch of workarounds that seemed to have spotty (at best) rates of success including seting QT’s graphics system to Native and giving Xorg over to root. They, mostly, seemed to be cargo cult solutions.

What made the most sense to my (generally questionable) mind was to use X forwarding. Since I had already been running Bitmessage over X forwarding from my Arch box, I knew it should work just the same.

To be completely truthful, the first pass I took at this was with Vagrant mostly because it’s SO easy. Bring up your Vagrant Box and then:
vagrant ssh -- -X
Viola!

Having proof of concept, I wanted a Docker container. The reason for this is practical. Vagrant, while completely awesome, has substantially more overhead than Docker by virtualizing the kernel. We don’t want a separate kernel running for each application. Therefore Docker is the better choice for this project.

Also, we want this whole thing to be seemless. We want to run the command bitmessage and it should fire up with minimal awkwardness and hopefully no extra steps. That is we do not want to run the Docker container then SSH into it and execute Bitmessage as individual steps. Even though that’s going to be how we begin.

The Bitmessage wiki accurately describes how to install the software so we’ll focus on the SSH setup. Though when we build the Dockerfile we will need to add SSH to the list from the wiki.

We’re going to want the container to start so that the SSH daemon is ready. Until then we can’t SSH (with X forwarding) into the container. Then we’ll want to use SSH to kick off the Bitmessage application, drawing the graphical interface using our host system’s X11.

We’re going to take advantage of Docker’s -v --volume option which allows us to specify a directory on our host system to be mounted inside our container. Using this feature, we’ll generate our SSH keys on the host and make them automatically available inside the container. We’ll tuck the keys inside the directory that Bitmessage uses for storing its configuration and data. That way Bitmessage’s configuration and stored messages can be persistent between runs — and all of your pieces are kept in a single place.

When we generate the container /etc/ssh/sshd_config is configured to allow root login without password only (i.e., using keys). So here’s how we’ll get this done:
mkdir -p ~/.config/PyBitmessage/keys #Ensure that our data directories exist
cd ~/.config/PyBitmessage/keys
ssh-keygen -b 4096 -P "" -C $"$(whoami)@$(hostname)-$(date -I)" -f docker-bitmessage-keys #Generate our SSH keys
ln -fs docker-bitmessage-keys.pub authorized_keys #for container to see pubkey

Build our container (sources available at Github and Docker) and we’ll make the script to handle Bitmessage to our preferences. #!/bin/bash
# filename: bitmessage
set -euxo pipefail

# open Docker container:
# port 8444 available, sharing local directories for SSH and Bitmessage data
# detatched, interactive, pseudo-tty (-dit)
# record container ID in $DID (Docker ID)
DID=$(docker run -p 8444:8444 -v ~/.config/PyBitmessage/:/root/.config/PyBitmessage -v ~/.config/PyBitmessage/keys/:/root/.ssh/ -dit j0rg3/bitmessage-gui bash)

# find IP address of new container, record in $DIP (Docker IP)
DIP=$(docker inspect $DID | grep IPAddress | cut -d '"' -f 4)

# pause for one second to allow container's SSHD to come online
sleep 1

# SSH into container and execute Bitmessage
ssh -oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null -oIdentityFile=~/.config/PyBitmessage/keys/docker-bitmessage-keys -X $DIP ./PyBitmessage/src/bitmessagemain.py

# close container if Bitmessage is closed
docker kill $DID

Okay, let’s make it executable: chmod +x bitmessage

Put a link to it where it can be picked up system-wide: ln -fs ~/docker-bitmessage/bitmessage /usr/local/bin/bitmessage

There we have it! We now have a functional Bitmessage inside a Docker container. \o/

In a future post we’ll look at using eCryptfs to further protect our Bitmessage data stores.

Kicking the Crypto-tires

Some time ago I had begun work on my own Pastebin-type project with a few goals. Basically, I wanted to eat all the cakes — and have them too.

  • Both an online user interface and efficient CLI usage
  • Messages encrypted immediately such that database access does not provide one with the contents of the messages
  • Messages capable of self-destructing
  • Database schema that would allow rebuilding the user/message relationship, provided the same password but would not store those relationships
  • Also, JavaScript encryption to appeal to users who don’t know much about cryptography but would like to try
  • The project, honestly, was going swimmingly when derailed by the goings-on of life.

    One of the interesting components of the project was, of course, choosing crypto implementations. There are know shortcomings to handling it in JS but that’s still the most convenient for some users. Outside of the browser, server-side, you had all the same questions about which solution was best. Which protocol(s) should be available?

    Well, I’ve just learned about a project which I would have loved to have available back then. Project Wycheproof can help you test your crypto solutions against known problems and attacks. Featuring 80 tests probing at 40 known bugs, here’s a snip from the introduction:

    Project Wycheproof has tests for the most popular crypto algorithms, including

  • AES-EAXAES-GCM
  • AES-GCM
  • DH
  • DHIES
  • DSA
  • ECDH
  • ECDSA
  • ECIES
  • RSA
  • The tests detect whether a library is vulnerable to many attacks, including

  • Invalid curve attacks
  • Biased nonces in digital signature schemes
  • Of course, all Bleichenbacher’s attacks
  • And many more — we have over 80 test cases
  • Interesting stuff with exciting potential!

    Simple Protection with iptables, ipset and Blacklists

    Seems I’ve always just a few more things going on than I can comfortably handle. One of those is an innocent little server holding the beginnings of a new project.

    If you expose a server to the Internet, very quickly your ports are getting scanned and tested. If you’ve an SSH server, there are going to be attempts to login as ‘root’ which is why it is ubiquitously advised that you disable root login. Also why many advise against allowing passwords at all.

    We could talk for days about improvements; it’s usually not difficult to introduce some form of two-factor authentication (2FA) for sensitive points of entry such as SSH. You can install monitoring software like Logwatch which can summarize important points from your logs, such as: who has logged via SSH, how many times root was used, etc.

    DenyHosts and Fail2ban are very great ways to secure things, according to your needs.

    DenyHosts works primarily with SSH and asks very little from you in way of configuration, especially if you’re using a package manager to install a version that is configured for the distribution on which you’re working. If you’re installing from source you may need to find where are your SSH logs (e.g., /var/log/secure, /var/log/auth.log). It’s extremely easy to set up DenyHosts to synchronize so that you’re automatically blocking widely-known offenders whether or not they’re after your server.

    In contrast, Fail2ban is going to take more work to get set up. However, it is extremely configurable and works with any log file you point it toward which means that it can watch anything (e.g., FTP, web traffic, mail traffic). You define your own jails which means you can ban problematic IP addresses according to preference. Ban bad HTTP attempts from HTTP only or stick their noses in the virtual corner and don’t accept any traffic from them until they’ve served their time-out by completely disallowing their traffic. You can even use Fail2ban to scan its own logs, so repeating offenders can be locked out for longer.

    Today we’re going to assume that you’ve a new server that shouldn’t be seeing any traffic except from you and any others involved in the project. In that case, you probably want to block traffic pretty aggressively. If you’ve physical access to the server (or the ability to work with staff at the datacenter) then it’s better to err in the direction of accidentally blocking good guys than trying to be overly fault-tolerant.

    The server we’re working on today is a Debian Wheezy system. It has become a common misconception that Ubuntu and Debian are, intents and purposes, interchangeable. They’re similar in many respects and Ubuntu is great preparation for using Debian but they are not the same. The differences, I think, won’t matter for this exercise but I am unsure because this was written using Wheezy.

    Several minutes after bringing my new server online, I started seeing noise in the logs. I was still getting set up and really didn’t want to stop and take protective measures but there’s no point in securing a server after its been compromised. The default Fail2ban configuration was too forgiving for my use. It was scanning for 10 minutes and banning for 10 minutes. Since only a few people should be accessing this server, there’s no reason for anyone to be trying a different password every 15 minutes (for hours).

    I found a ‘close-enough’ script and modified it. Here, we’ll deal with a simplified version.

    First, lets create a name for these ne’er-do-wells in iptables:
    iptables -N bad_traffic

    For this one, we’ll use Perl. We’ll look at our Apache log files to find people sniffing ‘round and we’ll block their traffic. Specifically, we’re going to check Apache’s ‘error.log’ for the phrases ‘File does not exist’ and ‘client denied by server configuration’ and block people causing those errors. This would be excessive for servers intended to serve the general populace. For a personal project, it works just fine as a ‘DO NOT DISTURB’ sign.


    #!/usr/bin/env perl
    use strict;
    use POSIX qw(strftime);

    my $log = ($ARGV[0] ? $ARGV[0] : "/var/log/apache2/error.log");
    my $chain = ($ARGV[1] ? $ARGV[1] : "bad_traffic");

    my @bad = `grep -iE 'File does not exist|client denied by server configuration' $log |cut -f8 -d" " | sed 's/]//' | sort -u`;
    my @ablk = `/sbin/iptables -S $chain|grep DROP|awk '{print $4}'|cut -d"/" -f1`;

    foreach my $ip (@bad) {
    if (!grep $_ eq $ip, @ablk) {
    chomp $ip;
    `/sbin/iptables -A $chain -s $ip -j DROP`;
    print strftime("%b %d %T",localtime(time))." badht: blocked bad HTTP traffic from: $ip\n";
    }
    }

    That gives us some great, utterly unforgiving, blockage. Looking at the IP addresses attempting to pry, I noticed that most of them were on at least one of the popular block-lists.

    So let’s make use of some of those block-lists! I found a program intended to apply those lists locally but, of course, it didn’t work for me. Here’s a similar program; this one will use ipset for managing the block-list though only minor changes would be needed to use iptables as above:

    #!/bin/bash
    IP_TMP=ip.tmp
    IP_BLACKLIST_TMP=ip-blacklist.tmp

    IP_BLACKLIST=ip-blacklist.conf

    WIZ_LISTS="chinese nigerian russian lacnic exploited-servers"

    BLACKLISTS=(

    done < $IP_BLACKLIST
    else
    echo -e '\nipset not found\n'
    echo -e "\nYour bloxlist file is: $IP_BLACKLIST\n"
    fi

    Managing to use man pages through simple CLI tips

    Recently, an author I admire and time-honored spinner of the Interwebs, Tony Lawrence emphasized the value of using man pagesmanual pagesDocumentation available from the command line.
    > man ls
    as a sanity check before getting carried away with powerful commands. I didn’t know about this one but he has written about a situation in which killall could produce some shocking, and potentially quite unpleasant, results.

    Personally, I often quickly check man pages to be certain that I am using the correct flags or, as in the above case, anticipating results that bear some resemblance to what is actually likely to happen. Yet, it seems many people flock toward SERPSearch Engine Results Page A tasteful replacement for mentioning any particular search-engine by name.
    Also useful as a verb:
    I dunno. You’ll have to SERP it.
    s for this information.

    Perhaps the most compelling reason to head for the web is leaving the cursor amid the line you’re working on, without disturbing the command. SERPing the command however, could easily lead you to information about a variant that is more common than the one available to you. More importantly, the information retrieved from the search engine is almost certainly written by someone who did read the man page — and may even come with the admonishment that you RTFMRead The F#!$!*#’n Manual as a testament to the importance of developing this habit.

    This can be made easier with just a few CLI shortcuts.

    <CTRL+u> to cut what you have typed so far and <CTRL+y> to paste it back.

    That is, you press <CTRL+u> and the line will be cleared, so you can then type man {command} and read the documentation. Don’t hesitate to jot quick notes of which flags you intend to use, if needed. Then exit the man page, press <CTRL+y> and finish typing right where you left off.

    This is another good use for screen or tmux but let’s face it. There are times when you don’t want the overhead of opening another window for a quick look-up and even instances when these tools aren’t available.

    A few other tips to make life easier when building complex commands:

    Use the command fc to open up an editor in which you can build your complex command and, optionally, even save it as a shell script for future reuse.

    Repeat the last word from the previous command (often a filename) with <ALT+.> or use an item from the last command by position, in reverse order:
    > ls -lahtr *archive*
    <ALT+1+.> : *archive*
    <ALT+2+.> : -lahtr
    <ALT+3+.> : ls

    You can also use Word Designators to use items from history, such as adding sudo to the last command typed by:
    sudo !!

    This allows for tricks like replacing bits of a previous command:
    !:s/misspelled/corrected/

    Lastly, if you need a command that was typed earlier, you can search history by pressing <CTRL+r> and start typing an identifying portion of the command.

    (Note: I have used these in Zsh and Bash, specifically. They can, however, be missing or overwritten — if a feature you want isn’t working, you can bind keys in a configuration file. Don’t just write it off, once you’ve solved the problem it will never again be an intimidating one.)

    Happy hacking!

    Painless protection with Yubico’s Yubikey

    Recently, I ordered a Yubikey and, in the comments section of the order, I promised to write about the product. At the time, I assumed that there was going to be something about which to write: (at least a few) steps of setting up and configuration or a registration process. They’ve made the task of writing about it difficult, by making the process of using it so easy.

    Plug it in. The light turns solid green and you push the button when you need to enter the key. That’s the whole thing!

    Physically, the device has a hole for a keychain or it can slip easily into your wallet. It draws power from the USB port on the computer, so there’s none stored in the device, meaning it should be completely unfazed if you accidentally get it wet.

    Let’s take a look at the device.

    > lsusb | grep Yubico

    There’s not a great deal to be seen here. As it tells you right on Yubico’s site, the device presents as a keyboard and it “types” out its key when you press the button, adding another long and complex password to combine with the long and complex password that you’re already using.

    Keep in mind that this device is unable to protect you from keyloggers, some of which are hardware-based. It’s critically important that you are very, very careful about where you’re sticking your Yubikey. Even Yubico cannot protect us from ourselves.

    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!

    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.
