Wordlists (IMPORTANT)

Summary:

Wordlist is a text file, each line is a path.
About extensions, Afuzz replaces the %EXT% keyword with extensions from -e flag.If no flag -e, the default is used.
Generate a dictionary based on domain names. Afuzz replaces %subdomain% with host, %rootdomain% with root domain, %sub% with subdomain, and %domain% with domain. And generated according to %ext%

Examples:

Normal extensions

index.%EXT%

Passing asp and aspx extensions will generate the following dictionary:

index
index.asp
index.aspx

host

%subdomain%.%ext%
%sub%.bak
%domain%.zip
%rootdomain%.zip

Passing https://test-www.hackerone.com and php extension will genrate the following dictionary:

test-www.hackerone.com.php
test-www.zip
test.zip
www.zip
testwww.zip
hackerone.zip
hackerone.com.zip

How to use

Some examples for how to use Afuzz - those are the most common arguments. If you need all, just use the -h argument.

Simple usage

afuzz -u https://target

afuzz -e php,html,js,json -u https://target

afuzz -e php,html,js -u https://target -d 3

Threads

The thread number (-t | --threads) reflects the number of separated brute force processes. And so the bigger the thread number is, the faster afuzz runs. By default, the number of threads is 10, but you can increase it if you want to speed up the progress.

In spite of that, the speed still depends a lot on the response time of the server. And as a warning, we advise you to keep the threads number not too big because it can cause DoS.

afuzz -e aspx,jsp,php,htm,js,bak,zip,txt,xml -u https://target -t 50

Blacklist

The blacklist.txt and bad_string.txt files in the /db directory are blacklists, which can filter some pages

The blacklist.txt file is the same as dirsearch.

The bad_stirng.txt file is a text file, one per line. The format is position==content. With == as the separator, position has the following options: header, body, regex, title

Language detection

The language.txt is the detection language rule, the format is consistent with bad_string.txt. Development language detection for website usage.
