Dockerized Canarytokens

by Thinkst Applied Research

Overview

Canarytokens helps track activity and actions on your network.

Prerequisites

• At least one domain name. If you want to enabled PDF-opening tracking, at least two domains.
• Internet-facing Docker host. You can install Docker on a Linux host quickly.

Setup (in Ubuntu)

• Boot your Docker host, and take note of the public IP.
• Configure your domains so that their nameservers point to the public IP of the Docker host. This requires a change at your Registrar, simply changing NS records in the zonefile is insufficient.
• Clone the Docker setup:

$ git clone https://github.com/Ictcmn/canarytokens-docker
$ cd canarytokens-docker

• Install Docker compose (if not already present):

$ sudo apt-get install python-pip python-dev
$ sudo pip install -U docker-compose
#if this breaks with PyYAML errors, install the libyaml development package
# sudo apt-get install libyaml-dev

• Configuration is held in the two .env files. Edit these. Uncomment 'CANARY_PUBLIC_DOMAIN' in switchboard.ev and set it to one of the domains defined for 'CANARY_DOMAIN' in frontend.ev(if you do not uncomment and set it, the Public IP will be used). If you are using Mailgun to send emails, uncomment 'CANARY_MAILGUN_DOMAIN_NAME' and 'CANARY_MAILGUN_API_KEY' from switchboard.ev and set the values. If you are using Mandrill instead, uncomment 'CANARY_MANDRILL_API_KEY' and set it. Here's example files for a setup that generates tokens on example1.com, example2.com and example3.com (PDFs), running on a host with public domain 'my.domain' and IP 1.1.1.1, using Mailgun Domain Name 'x.y' and API Key 'zzzzzzzzzz':
  • frontend.ev

#These domains are used for general purpose tokens
CANARY_DOMAINS=example1.com,example2.com

#These domains are only used for PDF tokens
CANARY_NXDOMAINS=example3.com

• switchboard.ev (using Mailgun for email)

CANARY_MAILGUN_DOMAIN_NAME=x.y
CANARY_MAILGUN_API_KEY=zzzzzzzzzz
#CANARY_MANDRILL_API_KEY=
CANARY_PUBLIC_IP=1.1.1.1
CANARY_PUBLIC_DOMAIN=my.domain
[email protected]
CANARY_ALERT_EMAIL_FROM_DISPLAY="Example Canarytokens"
CANARY_ALERT_EMAIL_SUBJECT="Canarytoken"

• Finally, download and instatiate the images:

$ docker-compose up

• The frontend and switchboard will now be running in the foreground. The frontend is accessible at http://example1.com/generate

Persisting data

The tokens are saved in a Redis database file which exists outside the Docker containers. Look for dump.rdb in the canarytokens-docker/data directory.

If you want to wipe all your tokens, delete dump.rdb.
