TukTuk

This project was initially started as a part of Digital Security's internship "Summer of Hack 2020".

TukTuk is an open source tool that designed to make pentester's life easier by catching and logging different types of requests. TukTuk is written in Go, but has a little part of python code.

Also if you wondering why project naming is so strange - TukTuk stands for Knock-Knock in Russian.

How to install

Requirements

• Golang >= 1.14.2
• PostgreSQL >= 12.1
• DNS domain
• If you want SMB protocol to work you will need to install impacket fork. You can do this with pip pip3 install git+https://github.com/ArturSS7/impacket.git@master

Setting up DNS

In order to set up DNS do the following:

• Make A record ns.example.com which points your ip
• Make NS record e.example.com with contents of ns.example.com
• Make A record on example.com which points your ip
• Make MX record on example.com

Example shows how to setup TukTuk for *.h.example.com if your VPS' IP is 1.3.3.7. Main DNS is Cloudflare in our case, but you can use what you want

Building project and setting up database

Just run two scripts:

• install.sh
• db_init.sh

After doing the project will be moved to $GOPATH/src/TukTuk You can run it with ./TukTuk

Configuring

The example configuration file is located in config/Config.json.example. There you can configure your domain settings, credentials and alerts Move the file to Config.json if you are going to run the project. Please change default credentials.

Configuring alerts

Telegram configuring

Create a bot and get a token is here. You can get Chatid using this bot @m4n_idbot. Set Telegram token in the TelegramBot field. In the Chatid field, set your chat id. The default length of the alert is "short" (protocol name + source ip + link to the admin panel), "long alert" - all information about the message)

Discord Webhook configuring

1. Go to Server settings -> Webhooks -> Create Webhook.
2. Setup name, avatar and the channel, where it will be posted. Copy Webhook URL. Do not share! Very dangerous!
3. Click Save and then the Done button.

Set Discord Webhook URL in the Webhook field.

Quickstart Gmail API configuring

Go to Quickstart Go to get the Config.json file then put it at the emailalert/Config.json path and run tuktuk. After starting, follow the generated link and give permission to send emails. Enter the received token into the console. Restart the server. Yes, it's not convenient. In the future we will bring the configuration to the admin panel.

Getting HTTPS certificate

You will have to get a wildcard certificate for your domain. You can do this with cert-bot. A good article which will help you is here. First start the app and then start the bot. During setting up certificates cert-bot will ask you to add TXT challenge to you domain. Add the TXT challenge in the Config.json file and continue. After getting certificate put its path to the config file.

Supported protocols:

• HTTP
• HTTPS
• DNS
• FTP
• LDAP
• SMTP (part of the code taken from go-smtp)
• SMB (used impacket's SMB realisation)
• Plain TCP

Alerting

TukTuk is designed not only to log requests, but to alert in case of it. Current alert options are:

• Telegram
• Discord Webhook
• GMail

Additional alert types can be added by writing a module. Feel free to make a pull request!

Web interface

TukTuk is featuring a little web interface where user can manage some of the settings or look for logged request.
