Sephiroth

A Python3 script to build cloud block lists for servers.

Requirements

  • Python 3.6+ (Sephiroth makes use of f-strings)

Setup

It is recommended to install the requirements into a virtual environment. From a brand new Ubuntu 18.04 machine, the setup flow should look something like this:

$ sudo apt install python3 python3-venv git
$ git clone https://github.com/0xdade/sephiroth.git
$ cd sephiroth/
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install -r requirements.txt

Usage

Sephiroth provides a built in help menu through the use of Python's argparse library. It tells you which commands are required, as well as other options.

sephiroth on  master [+] via sephiroth
➜ python sephiroth.py --help
usage: Sephiroth [-h] -s {nginx} -c {aws,azure,gcp} [-p] [--no-ipv6] [-V]

Sephiroth is made to help block clouds.

optional arguments:
  -h, --help            show this help message and exit
  -s {nginx}, --server {nginx}
                        Type of server to build blocklist for
  -c {aws,azure,gcp}, --cloud {aws,azure,gcp}
                        Cloud provider(s) to block
  -p, --proxy           Using PROXY Protocol?
  --no-ipv6             Exclude ipv6 addresses from the block list where
                        applicable
  -V, --version         show program's version number and exit

Example

sephiroth on  master [!] via sephiroth took 6s
➜ python sephiroth.py -s nginx -c aws -c azure
Your nginx blocklist for aws, azure can be found at ./output/nginx_aws_azure_2020-02-16_040129.conf

Please add this line to /etc/nginx/nginx.conf before the Virtual Host Configs.

        include /mnt/c/Users/dade/Desktop/sephiroth/output/nginx_aws_azure_2020-02-16_040129.conf;

Then you can use the $block_ip variable in your site config like so:

        if ($block_ip) {
                return 302 https://example.com;
        }

Supported Servers

  • nginx - Makes use of nginx's "ngx_http_geo_module" which comes with the nginx package in Ubuntu 18.04. Optionally supports the use of proxy_protocol, in the event that you are using a PROXY-enabled redirector.

Supported Cloud Providers

  • aws - Amazon Web Services. Obtained via the documented download process.
  • azure - Azure Cloud. Fetched via a two part process. Fetch the html of the download page and then parse the html to get the failoverLink anchor tag. That JSON is then downloaded.
  • gcp - Google Cloud Platform. Fetched via the absolutely insane abuse of spf records as outlined in the docs.
  • oci - Oracle Cloud Infrastructure. Fetched via the documented download process
