#### CLI tool for detecting subdomain takeovers

Subdominator is an open source tool with a command line interface for identifying subdomain takeovers.
This tool comes from StratusSecurity, an Australian security company.
The source code is available at <https://github.com/Stratus-Security/Subdominator>

**How to use it**

Using the snap is pretty straight forward.

To quickly check a list of domains, simply run:

`subdominator -l subdomains.txt -o takeovers.txt`

Or to quickly check a single domain, run:

`subdominator -d sub.example.com`

**Options**

```
-d, --domain <domain>    A single domain to check
-l, --list <list>        A list of domains to check (line delimited)
-o, --output <output>    Output subdomains to a file
-t, --threads <threads>  Number of domains to check at once [default: 50]
-v, --verbose            Print extra information
-eu, --exclude-unlikely  Exclude unlikely (edge-case) fingerprints
--validate               Validate the takeovers are exploitable (where possible)
--version                Show version information
-?, -h, --help           Show help and usage information
```
