Raspbian: GlastopfPi sebuah Web Honeypot

Jump to navigation Jump to search

Glastopf adalah sebuah aplikasi web honeypot project di pimpin oleh Lukas Rist a.k.a glaslos dari Honeynet Project. Glastopf project di mulai tahun 2009. It is a simple and minimalistic web server written in Python that records information of web-based application attacks like Structured Query Language Injection (SQLI), Remote Code Execution (RCE), Local File Inclusion (LFI), Remote File Inclusion (RFI), and many more, because it emulates web application vulnerabilities tricking attackers or scanners that it is a vulnerable web server.

Here are some snippets of the README file for this project in order to understand this web application honeypot better:

The adversaries usually use search engines and special crafted search requests to find their victims. In order to attract them, Glastopf provide those keywords (aka Dork) and extracts them also from request and extends its attack surface automatically. So over time and with a growing number of attacks, the honeypot gets more and more attractive. In the feature we will make the SQL injection emulator pubic, provide IP profiling for crawler recognition and intelligent Dork selection.

Glastopf has also hpfeeds, which is a central logger of the project that reports the events, but it can actually be turned off under the glastopf.cfg configuration file.

Prerequisites

  • A raspberry pi board (I tested this setup using the B Model).
  • The Soft-float Debian “wheezy” Linux, which can be downloaded here free: http://www.raspberrypi.org/downloads
  • A Micro SD card of at least 4GB in size
  • An Internet Access

Setting up the image

  • Extract the image file from the downloaded .zip file and you should have a name-of-thedistribution.img file after.
  • Insert the Micro SD card into your reader to your computer.
  • Download Win32DiskImager and then install it.
  • Run the .exe file as an Administrator and select the image file.
  • Select the drive letter of the Micro SD card in the device box, select the image of the distribution, and then click Write.
  • Wait for it until the utility finishes writing the image of the distribution to your Micro SD card.
  • Now, boot your Raspberry Pi with your Micro SD Card.

Install Dependency

Tambahkan backports repository ke file sources list di directory /etc/apt 

vi /etc/apt/sources.list

deb http://backports.debian.org/debian-backports squeeze-backports main

Update keyring 

gpg --keyserver pgpkeys.mit.edu --recv-key  8B48AD6246925553      
gpg -a --export 8B48AD6246925553 | sudo apt-key add -

Install dependency 

sudo apt-get update
sudo apt-get install python python-openssl python-gevent libevent-dev \
python-dev build-essential make python-argparse python-chardet \
python-requests python-sqlalchemy python-lxml python-beautifulsoup \

Install & konfigurasi PHP sandbox

Konfigurasi PHP sandbox.

Pertama-tama, download BFR (Better Function Replacer) menggunakan git: 

sudo apt-get install git-core
cd /opt
git clone git://github.com/glastopf/BFR.git
cd BFR
phpize
./configure --enable-bfr
make &&  make install

Di akhir proses akan keluar kata-kata 

Build complete.
Don't forget to run 'make test'.
Installing shared extensions:     /usr/lib/php5/20100525+lfs/

Lanjutkan 

make test

Tambahkan bfr.so ke php.ini 

vi /etc/php5/cli/php.ini

zend_extension = /usr/lib/php5/20100525+lfs/bfr.so

Cek menggunakan perintah 

php --version

Hasilnya 

PHP 5.4.36-0+deb7u3 (cli) (built: Jan 13 2015 01:07:43) 
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies
    with Better Function Replacer (BFR) v0.1, , by Lukas Rist

Install Glastopf 

sudo pip install glastopf

Proses ini akan lama karena harus mendownload berbagai file source code dan mengcompile-nya.

Konfigurasi dan Siapkan Environment untuk Glastopf

Siapkan folder 

mkdir -p /opt/glastopfi

Matikan apache2 karena honeypot akan mendengarkan port 80 

sudo service apache2 stop

Jalankan honeypot 

cd /opt/
sudo glastopf-runner

Akan keluar

File glastopf.cfg akan dibuat di folder /opt/glastopfi . Kita dapat customisasi sesuai dengan yang kita inginkan, minimal kita dapat mengubah agar port yang digunakan bukan 80 jika kita ingin menggunakan port lain.
