  • Conpot - ICS/SCADA Honeypot. Conpot is a low interactive server side Industrial Control Systems honeypot designed to be easy to deploy, modify and extend. By providing a range of common industrial control protocols we created the basics to build your own system, capable to emulate complex infrastructures to convince an adversary that he just found a huge industrial complex. To improve the deceptive capabilities, we also provided the possibility to server a custom human machine interface to increase the honeypots attack surface. The response times of the services can be artificially delayed to mimic the behaviour of a system under constant load. Because we are providing complete stacks of the protocols, Conpot can be accessed with productive HMI's or extended with real hardware. Conpot is developed under the umbrella of the Honeynet Project and on the shoulders of a couple of very big giants.

  • Bifrozt - Bifrozt is a NAT device with a DHCP server that is usually deployed with one NIC connected directly to the Internet and one NIC connected to the internal network. What differentiates Bifrozt from other standard NAT devices is its ability to work as a transparent SSHv2 proxy between an attacker and your honeypot. If you deployed an SSH server on Bifrozt’s internal network it would log all the interaction to a TTY file in plain text that could be viewed later and capture a copy of any files that were downloaded. You would not have to install any additional software, compile any kernel modules or use a specific version or type of operating system on the internal SSH server for this to work. It will limit outbound traffic to a set number of ports and will start to drop outbound packets on these ports when certain limits are exceeded.

Additionally it includes many useful pre-configured scripts and utilities to analyze, visualize and process the data it can capture, such as Kippo-Graph, Honeyd-Viz, DionaeaFR, an ELK stack and much more. Lastly, almost 90 well-known malware analysis, forensics and network monitoring related tools are also present in the distribution.
  • Cuckoo Sandbox - Cuckoo Sandbox is an Open Source software for automating analysis of suspicious files. To do so it makes use of custom components that monitor the behavior of the malicious processes while running in an isolated environment.
  • T-Pot Honeypot Distro - T-Pot is based on the network installer of Ubuntu Server 16/17.x LTS. The honeypot daemons as well as other support components being used have been containerized using docker. This allows us to run multiple honeypot daemons on the same network interface while maintaining a small footprint and constrain each honeypot within its own environment. Installation over vanilla Ubuntu - T-Pot Autoinstall - This script will install T-Pot 16.04/17.10 on a fresh Ubuntu 16.04.x LTS (64bit). It is intended to be used on hosted servers, where an Ubuntu base image is given and there is no ability to install custom ISO images. Successfully tested on vanilla Ubuntu 16.04.3 in VMware.
