Fast subdomain enumeration tool.

Usage
Running SubCat

#
SubCat a subdomain discovery tool that discovers valid subdomains for websites by using passive online sources. It has a simple modular architecture and is optimized for speed. SubCat is built for doing one thing only - passive subdomain enumeration, and it does that very well.

We have designed SubCat to comply with all passive sources licenses, and usage restrictions, as well as maintained a consistently passive model to make it useful to both penetration testers and bug bounty hunters alike.

### Features

demo

- Fast and powerful resolution and wildcard elimination module
- **Curated** passive sources to maximize results
- Optimized for speed, very fast and **lightweight** on resources
- **STDIN/OUT** support for integrating in workflows
- Scope limitation based on given IP ranges list

### Install
```
# Linux, Windows, MacOS
pip3 install -r requirements.txt
```

### Post Installation

API Key is needed before querying on third-party sites, such as ```Shodan, SecurityTrails, Virustotal,``` and ```BinaryEdge```.

- The API key setting can be done via `config.yaml`.

An example provider config file

```yaml

binaryedge:
- 0bf8919b-aab9-42e4-9574-d3b639324597
- ac244e2f-b635-4581-878a-33f4e79a2c13

virustotal:
- AAAAClP1bJJSRMEAAAAClP1bJJSRMEYJazgwhJKrggRwKAYJazgwhJKrggRwKA
securitytrails: []
shodan:
- AAAAClP1bJJSRMEYJazgwhJKrggRwKA

```

### Usage

```console
python3 subcat.py -h
```
This will display help for the tool. Here are all the switches it supports.

```yaml
Flags:
INPUT:
-d --domain string domains to find subdomains for
-l DOMAINLIST file containing list of domains for subdomain discovery
--scope SCOPE show only subdomains in scope

OUTPUT:
-sc, --status-code show response status code
-ip, --ip resolve IP address
-title, --title show page title
-silent, --silent show only subdomains in output
-o OUTPUT, --output OUTPUT
file to write output to

CONFIG:
-t THREADS, --threads THREADS
number of concurrent threads for resolving (default 40)

DEBUG:
-v show verbose output
-h, --help show this help message and exit
```
