Heralding

About

Sometimes you just want a simple honeypot that collects credentials, nothing more. Heralding is that honeypot! Currently the following protocols are supported: ftp, telnet, ssh, http, https, pop3, pop3s, imap, imaps, smtp, vnc, postgresql and socks5.

You need Python 3.7.0 or higher.

Viewing the collected data

Heralding logs relevant data in three files, log_session.json, log_auth.csv and log_session.csv.

log_session.json

This log file contains all available information for a given activity to the honeypot. This included timestamp, authentication attempts and protocol specific information (auxiliary data) - and a bunch of other information. Be aware that the log entry for a specific session will appear in the log file after the session has ended. The format is jsonlines.

log_session.csv

This log file contains entries for all connections to the honeypot. The data includes timestamp, duration, IP information and the number of authentication attempts. Be aware that the log entry for a specific session will appear in the log file after the session has ended.

log_auth.csv

This log file contains information for all authentication attempts where it was possible to log a username and plaintext password. Log entries will appear in this file as soon as the password has been transmitted.

Installing Heralding

For step by step instructions on how to install and run heralding in a Python virtual environment using Ubuntu, see this guide. Otherwise, the basic installation instructions are below.

To install the latest stable (well, semi-stable) version, use pip:

pip install heralding

Make sure that requirements and pip is installed. Simple way to do this on a Debian-based OS is:

sudo apt-get install python-pip python-dev build-essential libssl-dev libffi-dev
sudo pip install -r requirements.txt

And finally start the honeypot:

mkdir tmp
cd tmp
sudo heralding

Docker Build

1.Checkout the code:

cd ~
git clone https://github.com/johnnykv/heralding.git
cd heralding

2.Build new Docker image and run it (Http localhost expose example of port 80 to localhost:8080):

sudo docker build -t heralding .

sudo docker run -p 8080:80 heralding

Visit your application in a browser at http://localhost:8080

3.Check the log files:

sudo docker ps

We need to copy the CONTAINER ID of our heralding image. Looking like 0beb67f1e92c.

sudo docker exec -it 0beb67f1e92c bash

And now you are in the work directory, you can read the log files by typing cat and the name of the file. Example:

cat log_auth.csv

Pcaps

Want a seperate pcap for each heralding session? Sure, take a look at the Curisoum project. Make sure to enable Curisoum in Heralding.yml!

Submitting code

The project uses Chromium code style, please make sure to follow this before submitting. You can use tools like yapf to autoformat - the config file can be found at the root of the repo (.style.yapf).
