Aiodnsbrute - DNS Asynchronous Brute Force Utility

published on 2022-07-03 12:30:00 UTC by Unknown
Content:


A Python 3.5+ tool that uses asyncio to brute force domain names asynchronously.

Speed

It's fast. Benchmarks on small VPS hosts put around 100k DNS resoultions at 1.5-2mins. An amazon M3 box was used to make 1 mil requests in just over 3 minutes. Your mileage may vary. It's probably best to avoid using Google's resolvers if you're purely interested in speed.

DISCLAIMER

  • Your ISP's and home router's DNS servers probably suck. Stick to a VPS with fast resolvers (or set up your own) if you're after speed.
  • WARNING This tool is capable of sending LARGE amounts of DNS traffic. I am not repsonsible if you DoS someone's DNS servers.

Installation

$ pip install aiodnsbrute

Note: using a virtualenv is highly recommended.

Alternate install

Alternately you can install the usual way:

$ git clone https://github.com/blark/aiodnsbrute.git
$ cd aiodnsbrute
$ python setup.py install .

Usage

Get help:

$ aiodnsbrute --help

Usage: cli.py [OPTIONS] DOMAIN

aiodnsbrute is a command line tool for brute forcing domain names
utilizing Python's asyncio module.

Options:
-w, --wordlist TEXT Wordlist to use for brute force.
-t, --max-tasks INTEGER Maximum number of tasks to run asynchronosly.
-r, --resolver-file FILENAME A text file containing a list of DNS resolvers
to use, one per line, comments start with #.
Default: use system resolvers
-v, --verbosity Increase output verbosity
-o, --output [csv|json|off] Output results to DOMAIN.csv/json (extension
automatically appended when not using -f).
-f, --outfile FILENAME O utput filename. Use '-f -' to send file
output to stdout overriding normal output.
--query / --gethostbyname DNS lookup type to use query (default) should
be faster, but won't return CNAME information.
--wildcard / --no-wildcard Wildcard detection, enabled by default
--verify / --no-verify Verify domain name is sane before beginning,
enabled by default
--version Show the version and exit.
--help Show this message and exit.

Examples

Run a brute force with some custom options:

$ aiodnsbrute -w wordlist.txt -vv -t 1024 domain.com

Run a brute force, supppess normal output and send only JSON to stdout:

$ aiodnbrute -f - -o json domain.com

...for an advanced pattern, use custom resovers and pipe output into the awesome jq:

$ aiodnsbrute -r resolvers.txt -f - -o json google.com | jq '.[] | select(.ip[] | startswith("172."))'

Wildcard detection enabled by default (--no-wildcard turns it off):

$ aiodnsbrute foo.com

[*] Brute forcing foo.com with a maximum of 512 concurrent tasks...
[*] Using recursive DNS with the following servers: ['50.116.53.5', '50.116.58.5', '50.116.61.5']
[!] Wildcard response detected, ignoring answers containing ['23.23.86.44']
[*] Wordlist loaded, proceeding with 1000 DNS requests
[+] www.foo.com 52.73.176.251, 52.4.225.20
100%|██████████████████████████████████████████████████████████████████████████████| 1000/1000 [00: 05<00:00, 140.18records/s]
[*] Completed, 1 subdomains found

NEW use gethostbyname (detects CNAMEs which can be handy for potential subdomain takeover detection)

$ aiodnsbrute --gethostbyname domain.com

Supply a list of resolvers from file (ignoring blank lines and starting with #), specify -r - to read list from stdin.

$ aiodnsbrute -r resolvers.txt domain.com

Thanks

  • Wordlists are from bitquark's dnspop repo (except the 10 mil entry one which I created using his tool).
  • Click for making CLI apps so easy.
  • tqdm powers the pretty progress bar!
  • aiodns for providing the Python async interface to pycares which makes this all possible!

Notes

  • You might want to do a ulimit -n to see how many open files are allowed. You can also increase that number using the same command, i.e. ulimit -n <2048>
