[-] Auxiliary failed: Msf::OptionValidateError The following options failed to validate: RHOSTS.

Mucking about with a fresh copy of Kali brings to attention that it’s packaged with an Armitage that doesn’t correctly work.

I know what you’re thinking… Good. Type the commands into Msfconsole like a real man, y’uh lazy good-fer-naught! And, in practice, that was my immediate solution. But I can’t resist a good tinker when things are misbehaving.

I was anticipating that the problem would be thoroughly solved when I ixquicked it. That was partially correct. Surprised, however, when apt-get update && apt-get upgrade didn’t fix the issue. More surprised at the age of the issue. Most surprised that I could see lots of evidence that users have been plagued by this issue — but no clear work arounds were quickly found.

Guess what we’re doing today?

Okay. The issue is quite minor but just enough to be heartbreaking to the fledgling pentester trying to get a VM off the ground.

In brief, the owner of Armitage’s Github explains:

The MSF Scans feature in Armitage parses output from Metasploit’s portscan/tcp module and uses these results to build a list of targets it should run various Metasploit auxiliary modules against. A recent-ish update to the Metasploit Framework changed the format of the portscan/tcp module output. A patch to fix this issue just needs to account for the new format of the portscan/tcp module.

That is, a colon makes it into the input for the Msfconsole command to define RHOSTS. I.e.: set RHOSTS 172.16.223.150: - 172.16.223.150

An other kind coder tweaked the regex and submitted the patch and pull request, which was successfully incorporated into the project.

Sadly, things have stalled out there. So if this problem is crippling your rig, let’s fix it!

We just want a fresh copy of the project.

Kali is Debian-based and we’re going to need Apache Ant:

Then, we’ll build our new fella:

And here, best I can guess from messages read, is where a lot of people are running into trouble. We have successfully produced our new working copy of armitage. However, it is in our own local directory and will not be run if we just enter the command: armitage

Let’s review how to figure out what we want to do about that.

First, we want to verify what happens when we run the command armitage.
root@kali:~/armitage# which armitage

/usr/bin/armitage

Good! Let’s check and see what that does!
root@kali:~/armitage# head /usr/bin/armitage

#!/bin/sh

cd /usr/share/armitage/
exec ./armitage “$@”

Almost there! It’s running /usr/share/armitage/armitage with whatever variables we’ve passed in. We’ll check that out.
root@kali:~/armitage# head /usr/share/armitage/armitage

#!/bin/sh
java -XX:+AggressiveHeap -XX:+UseParallelGC -jar armitage.jar $@

We have enough information to assemble a solution.

I trust that the people behind Kali and Armitage will get this corrected so I don’t want to suggest a solution that would replace the armitage command and prevent an updated version from running later. So, let’s just make a temporary replacement?

root@kali:~/armitage# echo -e '#!/bin/sh\njava -XX:+AggressiveHeap -XX:+UseParallelGC -jar ~/armitage/armitage.jar $@' > /usr/bin/tmparmitage

Hereafter, we can use the command ‘tmparmitage’ (either CLI or ALT-F2) to run our fresh version until things catch up.

And, of course, to save you the time, weary hacker:

Network-aware Synergy client

My primary machines are *nix or BSD variants, though I certainly have some Windows-based rigs also. Today we’re going to share some love with Windows 7 and PowerShell.

One of my favorite utilities is Synergy. If you’re not already familiar it allows to you seamlessly move from the desktop of one computer to another with the same keyboard and mouse. It even supports the clipboard so you might copy text from a GNU/Linux box and paste it in a Windows’ window. Possibly, they have finished adding drag and drop to the newer versions. I am not sure because I run a relatively old version that is supported by all of the machines that I use regularly.

What’s the problem, then? The problem was that I was starting my Synergy client by hand. Even more disturbing, I was manually typing the IP address at work and at home, twice or more per weekday. This behavior became automated by my brain and continued for months unnoticed. But this is no kind of life for a geek such as myself, what with all this superfluous clicking and tapping!

Today, we set things right!

In my situation, the networks that I use happen to assign IP addresses from different subnets. If you’ve not the convenience of that situation then you might need to add something to the script. Parsing an ipconfig/ifconfig command, you could possibly use something like the Default Gateway or the Connection-specific DNS Suffix. Alternatively, you could check for the presence of some network share, a file on server or anything that would allow you to uniquely identify the surroundings.

As I imagined it, I wanted the script to accomplish the following things

  • see if Synergy is running (possibly from the last location), if so ask if we need to kill it and restart so we can identify a new server
  • attempt to locate where we are and connect to the correct Synergy server
  • if the location is not identified, ask whether to start the Synergy client

This is how I accomplished that task:

# [void] simply supresses the noise made loading 'System.Reflection.Assembly'
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

# Define Synergy server IP addresses
$synergyServerWork = "192.168.111.11"
$synergyServerHome = "192.168.222.22"

# Define partial IP addresses that will indicate which server to use
$synergyWorkSubnets = "192.168.111", "192.168.115"
$synergyHomeSubnets = "192.168.222", "192.168.225"

# Path to Synergy Client (synergyc)
$synergyClientProgram = "C:\Program Files\Synergy\synergyc.exe"

# Path to Syngery launcher, for when we cannot identify the network
$synergyLauncherProgram = "C:\Program Files\Synergy\launcher.exe"

# Remove path and file extension to give us the process name
$processName = $synergyClientProgram.Substring( ($synergyClientProgram.lastindexof("\") + 1), ($synergyClientProgram.length - ($synergyClientProgram.lastindexof("\") + 5) ))

# Grab current IP address
$currentIPaddress = ((ipconfig | findstr [0-9].\.)[0]).Split()[-1]

# Find the subnet of current IP address
$location = $currentIPaddress.Substring(0,$currentIPaddress.lastindexof("."))


function BalloonTip ($message)
{
# Pop-up message from System Tray
$objNotifyIcon = New-Object System.Windows.Forms.NotifyIcon
$objNotifyIcon.Icon = [System.Drawing.Icon]::ExtractAssociatedIcon($synergyClientProgram)
$objNotifyIcon.BalloonTipText = $message
$objNotifyIcon.Visible = $True
$objNotifyIcon.ShowBalloonTip(15000)
}


#main

# If Synergy client is already running, do we need to restart it?
$running = Get-Process $processName -ErrorAction SilentlyContinue
if ($running) {
$answer = [System.Windows.Forms.MessageBox]::Show("Synergy is running.`nClose and start again?", "OHNOES", 4)
if ($answer -eq "YES") {
Stop-Process -name $processName
}
Else {
exit
}
}

# Do we recognize the current network?
if ($synergyWorkSubnets -contains $location) {
BalloonTip "IP: $($currentIPaddress)`nServer: $($synergyServerWork)`nConnecting to Synergy server at work."
& $synergyClientProgram $synergyServerWork
exit
}
ElseIf ($synergyHomeSubnets -contains $location) {
BalloonTip "IP: $($currentIPaddress)`nServer: $($synergyServerHome)`nConnecting to Synergy server at home."
& $synergyClientProgram $synergyServerHome
exit
}
Else {
$answer = [System.Windows.Forms.MessageBox]::Show("Network not recognized by IP address: {0}`n`nLaunch Synergy?" -f $unrecognized, "OHNOES", 4)
if ($answer -eq "YES") {
& $synergyLauncherProgram
}
}

Then I saved the script in "C:\Program Files\SynergyStart\", created a shortcut and used the Change Icon button to make the same as Synergy’s and made the Target:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -WindowStyle Hidden & 'C:\Program Files\SynergyStart\synergy.ps1'

Lastly, I copied the shortcut into the directory of things that run when the system starts up:
%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup

Now, Synergy connects to the needed server at home and work. If it can’t figure out where it is, it asks if it should run it at all.

As they say, a millisecond saved is a millisecond earned.

This post was very nearly published without a Linux equivalent. Nearly.

Same trick for bash/zsh: #!/bin/zsh

# Define Synergy server IP addresses
synergyServerWork="192.168.111.11"
synergyServerHome="192.168.222.22"

# Define partial IP addresses that will indicate which server to use
synergyWorkSubnets=("192.168.111" "192.168.115")
synergyHomeSubnets=("192.168.222" "192.168.225")

# Path to Synergy Client (synergyc)
synergyClientProgram="/usr/bin/synergyc"

# Path to QuickSyngery, for when we cannot identify the network
synergyLauncherProgram="/usr/bin/quicksynergy"

# Remove path and file extension to give us the process name
processName=`basename $synergyClientProgram`

# Grab current IP address, assumes '192' is in use. (e.g., 192.168.1.1)
currentIPaddress=`ip addr show | grep 192 | awk "{print $2}" | sed 's/inet //;s/\/.*//;s/ //g'`

# Find the subnet of current IP address
location=`echo $currentIPaddress | cut -d '.' -f 1,2,3`

for i in "${synergyWorkSubnets[@]}"
do
if [ "${i}" = "${location}" ]
then
break
fi
done

#main

# If Synergy client is already running, do we need to restart it?
running=`ps ax | grep -v grep | grep $processName`
if [ $running ]
then
if `zenity --question --ok-label="Yes" --cancel-label="No" --text="Synergy is running.\nClose and start again?"`
then
pkill $processName
else
exit
fi
fi

# Do we recognize the current network?
for i in "${synergyWorkSubnets[@]}"
do
if [ "${i}" = "${location}" ]
then
notify-send "IP:$currentIPaddress Server:$synergyServerWork [WORK]"
$synergyClientProgram $synergyServerWork
exit
fi
done

for i in "${synergyHomeSubnets[@]}"
do
if [ "${i}" = "${location}" ]
then
notify-send "IP:$currentIPaddress Server:$synergyServerWork [HOME]"
$synergyClientProgram $synergyServerHome
exit
fi
done

if `zenity --question --ok-label="Yes" --cancel-label="No" --text="Network not recognized by IP address: $currentIPaddress\nLaunch Synergy?"`
then
$synergyLauncherProgram
fi

To get it to run automatically, you might choose to call the script from /etc/init.d/rc.local.

ixquick link maker

In an effort to promote practical privacy measures, when I send people links to search engines, I choose ixquick. However, my personal settings submit my search terms via POST data rather than GET, meaning that the search terms aren’t in the URL.

Recently, I’ve found myself hand-crafting links for people and then I paste the link into a new tab, to make sure I didn’t fat-finger anything. Not a problem per se, but the technique leaves room for a bit more efficiency. So I’ve taken the ‘A Search Box on Your Website’ tool offered by ixquick and slightly modified the code it offers, to use GET variables, in a new tab where I can then copy the URL and provide the link to others.

You can test, or use, it here — I may add it (or a variant that just provides you the link) to the navigation bar above. First, though, I’m going to mention the need to the outstanding minds at ixquick because it would make a LOT more sense on their page than on mine.

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
