# l337_5ub0v3r: A Fast Tool To Check Subdomain Takeover Vulnerability
## What is l337_5ub0v3r
l337_5ub0v3r is a tool written in python which is used to check possibility of subdomain takeover vulnerability and it is fast as it is asynchronous.
## Why
During recon process you might get a lot of subdomains(e.g more than 10k). It is not possible to test each manually or with traditional requests or urllib method as it is very slow. Using l337_5ub0v3r you can automate this task in much faster way. l337_5ub0v3r uses aiohttp/asyncio which makes this tool asynchronous and faster.
## How it works
l337_5ub0v3r uses subdomains list from text file and checks for url of 404 Not Found status code and in addition it fetches CNAME(Canonical name) and removes those URL which have target domain name in CNAME. It also combines result from subfinder and sublist3r(subdomain enumeration tool) if you don't have target subdomains as two is better than one. But for this sublist3r and subfinder tools must be installed in your system. l337_5ub0v3r is able to check 7K subdomains in less than 5 minutes.
## Key Features:
```
- Fast (as it is asynchronous)
- Uses two more tools to increase efficiency
- Saves result in a text file for future reference
- Umm that's it, nothing much !
```
## How to use:
Note: Only works on Python3.7+
- git clone https://github.com/abhinandan-khurana/l337_5ub0v3r.git
- Install dependencies: pip install -r requirements.txt
- Install [Subfinder](https://github.com/projectdiscovery/subfinder) (optional)
- Install [Sublist3r](https://github.com/aboul3la/Sublist3r) (optional)
- python3 l337_5ub0v3r.py -h
### Using docker
As an alternative, it is also possible to build a Docker image, so no prerequisites are necessary.
```
$ docker build -t l337_5ub0v3r .
$ docker run --rm l337_5ub0v3r -h
```
## Usage example:
Note: If subfinder and sublist3r is installed.
This combines result from sublist3r and subfinder tool and checks for possibility of takeover.
$ python3 l337_5ub0v3r.py -d anydomain.com
- If subfinder and sublist3r is not installed, provide subdomains in text file
$ python3 l337_5ub0v3r.py -f subdomain.txt
## Note:
This tool is mostly tested in linux but should works on other OS too.
## Usage options:
```
$ python3 l337_5ub0v3r.py -h
```
This will display help for the tool. Here are all the switches it supports.
|Flag | Description | Example |
|-----|------------------------------------------------------------------------|----------------------------------------------------------|
| -d | Domain name of the target. | python3 l337_5ub0v3r.py -d noobarmy.org |
| -f | Provide location of subdomain file to check for takeover if subfinder is not installed. | python3 l337_5ub0v3r.py -f subdomain.txt|
| -p | Set protocol for requests. Default is "http".| python3 l337_5ub0v3r.py -f subdomain.txt -p https or python3 l337_5ub0v3r.py -d noobarmy.org -p https|
| -o | Output unique subdomains of sublist3r and subfinder to text file. Default is "uniqueURL.txt" | python3 l337_5ub0v3r.py -d noobarmy.org -o output.txt|
| -h | show this help message and exit | python3 l337_5ub0v3r.py -h|
## Note:
```
This tool fetches CNAME of 404 response code URL and removes all URL which have target domain in CNAME. So chances of false positives are high.
