Get subdomains via additional recon (Search Engine, Alternative Sources)

[creolis]

This is more or less linked to #31, as it is just another idea to get more hostnames during the recon process :)

Google and Bing: Scrape Google and Bing using the site: modifier. Example: "site:foo.com" Parse the result set for individual subdomains.

Also:

AXFR: maybe a Zone transfer is possible, which would result in a comprehensive list of returns and therefore you can back off from brute force and safe time at that point :)

DNSSEC aware zones could be prone to zone walking, which is another great way to get a list of hosts in a considerable amount of time.

A rather "active" approach (which involves direct connections) could be to access each found host on port 80, retrieve the standard vhost and the vhost you found and look if you get a HTTP 302 Redirection - it may include further hints to other subdomains.

Subbrute tries an axfr against every authoritative ns record, because one of the servers maybe misconfigured.

As for non-dns methods, the next major version will open the flood gates for custom discovery.

Ah :) Didn't realize it already does axfr because I did not see an option switch for that, but I must admit I didn't look at the sources yet. Next major will be exciting then :-)
