Amun

Amun was the first python-based low-interaction honeypot, following the concepts of Nepenthes but extending it with more sophisticated emulation and easier maintenance.

Requirements

• Pyhon >= 2.6 (no Python3 support yet)
• (optional) Python Psyco (available at http://psyco.sourceforge.net/)
• (optional) MySQLdb if submit-mysql or log-mysql is used
• (optional) psycopg2 if log-surfnet is used

Installation

• Clone Git repository: git clone https://github.com/zeroq/amun.git
• Edit Amun main configuration file: vim conf/amun.conf
  • for example set the ip address for Amun to listen on (0.0.0.0 to listen on all)
  • enable or disbale vulnerability modules as needed
• start the Amun by issuing: ./amun_server

Tips and Tricks

In case you encounter problems with too many open files due to a lot of attackers hitting your honeypot at the same time, the following settings can be adjusted:

• To increase the maximum number of open files on Linux:
  • echo "104854" > /proc/sys/fs/file-max
  • ulimit -Hn 104854
  • ulimit -n 104854
• To increase the maximum number of open files on BSD:
  • sysctl kern.maxfiles=104854
  • ulimit -Hn 104854
  • ulimit -n 104854

Logging

All logging information are stored in the "logs" subdirectory of your Amun installation. Following log files will be created:

• amun_server.log
  • contains general information, errors, and alive messages of the amun server
• amun_request_handler.log
  • contains information about unknown exploits and not matched exploit stages
• analysis.log
  • contains information about manual shellcode analysis (performed via the -a option)
• download.log
  • contains information about all download modules (ftp, tftp, bindport, etc...)
• exploits.log
  • contains information about all exploits that where triggert
• shellcode_manager.log
  • contains information and errors of the shellcode manager
• submissions.log
  • contains information about unique downloads
• successfull_downloads.log
  • contains information about all downloaded malware
• unknown_downloads.log
  • contains information about unknown download methods
• vulnerabilities.log
  • contains information about certain vulnerability modules

Parameters

Amun can be executed with -a parameter to analyse a given file for known shellcode instead of running the honeypot.
