CTFR

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.
