⁠What's CTFR?

CTFR is a tool that allows to get the subdomains from HTTPS websites in a few seconds.
The github repository of this tool is: https://github.com/unapibageek/ctfr⁠.

⁠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.

$ docker container run --rm unapibageek/ctfr -d starbucks.com

Replace "starbucks.com" by whatever domain you want to get its subdomains.
