Short Description
Automatically bans ever-evading IP changing bots, known on Rizon as "vpn".
Full Description

Icedream's Anti-VPN bot

This bot automatically sets bans when it detects clients with specific patterns known from bots that evade bans and (probably) log channels.

The pattern is roughly as follows:

  • Nickname, Ident and Real name are the same (Ident shortened down to first 9 characters)
  • Client joins a very high amount of channels.
  • Client is not identified.
  • Client generates nicknames from a preset of words and random numbers.
  • Client connects from various IP addresses (botnet)
  • It optionally quits very soon with an "Excess Flood" message due to it spamming channel joins.

How to install this

go get -v github.com/icedream/vpnbot

Make sure your GOPATH is set properly and that you have PATH also pointing at your GOPATH binary folder.

How to run this

Using Docker

Docker allows an easy, isolated setup of vpnbot.

  1. Make sure you have Docker installed properly on your system.
  2. If you haven't yet, generate a configuration with this command: docker run --rm -v /path/to/your/data:/data icedream/vpnbot vpnbot -generate
  3. Edit the resulting config.yml to your needs, you'll probably need root permissions for this.
  4. Start up a container with Docker like this: docker run --rm -d -v /path/to/your/data:/data icedream/vpnbot
  5. Check if the bot started up correctly using docker logs <printed container ID here>.

Alternatively, after step 3 you can use docker-compose with a YAML configuration like this:

bot:
  image: icedream/vpnbot
  volumes:
  - "./data:/data"

Manually

First, generate a default configuration in a new folder:

mkdir vpnbot
cd vpnbot
vpnbot -generate

This will generate config.yml - the file path can be changed by appending -config "<your own path here>". Edit this file to your needs, then rerun the bot without -generate.

vpnbot

Again, optionally add -config "<your own path here>" if you use your own path to the configuration file.
