Dumb - A Faster And Flexible Domain Bruteforcer


A tool to bruteforce "dumains"!

How DUMB works:
Dumb works with a masked dumain for substitution. The dumain can have as many masks as you want as long as you pass the according wordlists. For example:

Bruteforcing subdumains:
Using the mask DUMB.dumain.com and the following wordlists:
www
ftp
backoffice
Dumb will generate the following dumains for bruteforce:
www.dumain.com
ftp.dumain.com
backoffice.dumain.com
For subdumains, you can only pass dumain.com and dumb will understand as DUMB.dumain.com.

Bruteforcing domain endings:
Using the same principle, you can pass as mask dumain.DUMB with the following wordlist:
com
net
org
Dumb will generate the following dumains for bruteforce:
dumain.com
dumain.net
dumain.org

Bruteforcing everything:
To bruteforce everything you can pass the mask as "DUMB.DUMB.DUMB" passing three wordlists:
wordlist1   wordlist2   wordlist3
www foo com
ftp bar net
Dumb will generate:
www.foo.com
ftp.foo.com
www.bar.com
ftp.bar.com
www.foo.net
ftp.foo.net
www.bar.net
ftp.bar.net

Usage:
Dumb receives the dumain mask as first parameter and the wordlists following. The number of wordlists must match the number of masks in the dumain. For example:
  • One mask:
    $ dumb "DUMB.dumain.com" wordlists/foo.txt
  • Two masks:
    $ dumb "DUMB.dumain.DUMB" wordlists/foo.txt wordlists/bar.txt
  • Several masks:
    $ dumb "DUMB-DUMB-DUMB_DUMB.DUMB.DUMB" wordlists/foo_1.txt ... wordlists/foo_6.txt

Docker:
If you don't want to build from source, you can use the docker version:
  • docker run -it giovanifss/dumb "DUMB.dumain.com" subdomains.txt
All the wordlists in wordlists/ are inside the docker container in filesystem root /, this means that you can call dumb passing the wordlists name:
  • docker run -it giovanifss/dumb "DUMB.dumain.com" (subdomains.txt|subdominios.txt|domain-endings.txt)
To work with local wordlists that aren't present inside the container, you can use docker volumes:
docker run -v local/wordlist.txt:/opt/wordlist.txt -it giovanifss/dumb "DUMB.dumain.com" /opt/wordlist.txt


Building from source:
If you want to build from source you will need stack:
  • Enter in the project directory and run $ stack build.
  • To execute:
    $ stack exec dumb "DUMB.dumain.com" wordlists/subdomains.txt
Note that some older versions of stack have some problems to build the project (Debian stack package, for example). Make sure you get the latest stack version.

Future features:
Future planned features are:
  • Argument parser support, for better configuration of the tool execution;
  • Post analysis of found dumains, generating statistics and metrics;

Performance:
The tool performance will highly depend on your network connection. Usually, it should take less then 10 seconds to finish a subdumain burteforce with the wordlists/subdomains.txt wordlist.
If you have a good connection and think that the tool is slow, try changing the 1000 in the splitDomains function call, e.g. mapM_ (MP.mapM_ (resolve rs)) (splitDomains 1000 allDomains), to a higher value.
Alternatively, you can change mapM_ (MP.mapM_ (resolve rs)) (splitDomains 1000 allDomains) to MP.mapM_ (resolve rs) allDomains to execute all the requests in parallel.
