Dome : Fast And Reliable Python Script That Makes Active And/Or Passive Scan To Obtain Subdomains

Dome is a fast and reliable python script that makes active and/or passive scan to obtain subdomains and search for open ports. This tool is recommended for bug bounty hunters and pentester in their reconnaissance phase.

If you want to use more OSINT engines, fill the config.api file with the needed API tokens

Passive Mode

Use OSINT techniques to obtain subdomains from the target. This mode will not make any connection to the target so it is undetectable. The basic use of this mode is:

python dome.py -m passive -d domain

Active Mode

Perform bruteforce attacks to obtain alive subdomains. There are 2 types of bruteforce:

• Pure Bruteforce: Check subdomains from a.domain.com to zzz.domain.com (26 + 26^2 + 26^3 = 18278 subdomains) this bruteforce can be disabled with -nb, --no-bruteforce
• Wordlist based: Use a custom wordlist provided by the user using the flag -w, --wordlist. If no wordlists is specified, this mode won’t be executed

This mode will also make passive mode attack but in this case, the connection is tested to ensure the subdomain is still alive. To disable passive scan in active scan mode, use --no-passive flag

The basic use of this mode is:

python dome.py -m active -d domain -w wordlist.txt

Add -p option or a built-it port option (see usage menu) to perform port scanning

python dome.py -m active -d domain -w wordlist.txt -p 80,443,8080

Installation

You can run Dome with Python 2 or 3. Python3 is recommended

Install the dependencies and run the program

git clone https://github.com/v4d1/Dome.git
cd Dome
pip install -r requirements.txt
python dome.py –help

Features

• Easy to use. Just install the requirements.txt and run
• Active and Passive scan (read above)
• Faster than other subdomain enumeration tools
• 7 different resolvers/nameservers including google, cloudfare (fastest), Quad9 and cisco DNS (use –resolvers filename.txt to use a custom list of resolvers, one per line)
• Up to 21 different OSINT sources
• Subdomains obtained via OSINT are tested to know if they are alive (only in active mode)
• Support for webs that requires API token
• Detects when api key is no longer working (Other tools just throw an error and stops working)
• Wildcard detection and bypass
• Custom Port scaning and built-in params for Top100,Top1000 and Top Web ports
• Colored and uncolored output for easy read
• Windows and Python 2/3 support (Python 3 is recommended)
• Highly customizable through arguments
• Scan more than one domain simultaneously
• Possibility to use threads for faster bruteforce scans
• Export output in different formats such as txt, json, html

Usage

Arguments	Description	Arg example
-m, –mode	Scan mode. Valid options: active or passive	active
-d, –domain	Domains name to enumerate subdomains (Separated by commas)	hackerone.com,facebook.com
-w, –wordlist	Wordlist containing subdomain prefix to bruteforce	subdomains-5000.txt
-i, –ip	When a subdomain is found, show its ip
–no-passive	Do not use OSINT techniques to obtain valid subdomains
-nb, –no-bruteforce	Dont make pure bruteforce up to 3 letters
-p, –ports	Scan the subdomains found against specific tcp ports	80,443,8080
–top-100-ports	Scan the top 100 ports of the subdomain (Not compatible with -p option)
–top-1000-ports	Scan the top 1000 ports of the subdomain (Not compatible with -p option)
–top-web-ports	Scan the top web ports of the subdomain (Not compatible with -p option)
-s, –silent	Silent mode. No output in terminal
–no-color	Dont print colored output
-t, –threads	Number of threads to use (Default: 25)	20
-o, –output	Save the results to txt, json and html files
–max-response-size	Maximun length for HTTP response (Default:5000000 (5MB))	1000000
–r, –resolvers	Textfile with DNS resolvers to use. One per line	resolvers.txt
-h, –help	Help command
–version	Show dome version and exit
-v, –verbose	Show more information during execution

Examples

Perform active and passive scan, show the ip adress of each subdomain and make a port scan using top-web-ports. Data will also be written in /results folder:

python dome.py -m active -d domain -w wordlist.txt -i –top-web-ports -o

Perform passive scan in silent mode and write output to files.

python dome.py -m passive -d domain –silent –output

Perform active scan without passive and port scan

python dome.py -m active -d domain -w wordlist.txt –no-passive

Only bruteforce with wordlist

python dome.py -m active -d domain -w wordlist.txt –no-bruteforce

Scan active and passive and perform port scan ONLY in ports 22,80,3306

python dome.py -m active -d domain -w wordlist.txt -p 22,80,3306
