Do you miss AXFR technique? This tool allows to get the subdomains from a HTTPS website in a few seconds.
How it works? CTFR does not use neither dictionary attack nor brute-force, it just abuses of Certificate Transparency logs.
For more information about CT logs, check www.certificate-transparency.org and crt.sh.
Please, follow the instructions below for installing and run CTFR.
Make sure you have installed the following tools:
Python 3.0 or later. pip3 (sudo apt-get install python3-pip).
$ git clone https://github.com/UnaPibaGeek/ctfr.git $ cd ctfr $ pip3 install -r requirements.txt
$ python3 ctfr.py --help
Parameters and examples of use.
-d --domain [target_domain] (required) -o --output [output_file] (optional)
$ python3 ctfr.py -d starbucks.com
$ python3 ctfr.py -d facebook.com -o /home/shei/subdomains_fb.txt
I think it's a little bit crazy to use Docker for running such a little python script, but if you want to do it anyway, you can use this Docker image.
The instructions are there.
