So, what is Wfuzz?
Wfuzz helps in fuzzing which is testing various entry points that can be exploited by attackers by identifying potential vulnerabilities. It is used to launch brute-force attacks, and can be used to identify various vulnerabilities.

Wfuzz is a tool that is used to discover web content and directories and it is designed to help security professionals automate the process of fuzzing. It has much more functionality than that: The top functionalities it offers are :
1 Web Content Discovery
2 Form Manipulation / Bruteforcing.

Using Wfuzz

Basic Wfuzz

Wfuzz -c [Options] URL

These are the most important options you are gonna use

-c : to color the output
-z : setting payload type (list, num, etc.)
-d : setting data to be sent with the request
-H : setting headers to be sent with the request
-e : setting encoding for the payload (url encode, hex, etc.)
-w : setting wordlist to be used for fuzzing
-p : setting the number of concurrent connections
-t : setting a timeout for each request
-s : setting the delay between each request
-L : following redirects

Here are the following Payload Types:
list : use a wordlist to fuzz the target
num : use a range of numbers to fuzz the target
alpha : use the alphabet to fuzz the target
alphanum : use a combination of numbers and letters to fuzz the target
hex : use hexadecimal values to fuzz the target

Here is how you are gonna incorporate this into command.

What is Wfuzz payload?

Wfuzz payload is a source of data. This helps it to inject it into any field and test it to perform complex security attacks.

Magic with Payloads

wfuzz -c -z list,wordlist.txt https://hackingblogs.com/FUZZ
What is Wfuzz?

What this command will do is it will take the words from the wordlist.txt and place them to the FUZZ keyword check or response if the assets/content exist it will give a 200 status and appear as a result.

What If you were Searching for Idors(Don’t worry if you do not know about idols go look at the one I have posted on hackingblogs.com) and you got a parameter where the users id’s are sourced by numbers you can use the numbers payload

wfuzz -c -z num,1-10 https://hackingblogs.com/user-id?=FUZZ

The fuzz keyword will be replaced by numbers 1-10 and check if a user with those users exists or not.

Subdomain Fuzzing

The keynote is that you will require a good wordlist containing all the important keywords so to fuzz items.

For example, we’ll be using the rockyou.txt wordlist to find subdomains.

wfuzz -c -Z -w rockyou.txt https://FUZZ.hackingblogs.com

-c -> color output
-Z -> Ignore connection error
-w -> wordlists
FUZZ -> The parameter where we’ll inject.

Directory Fuzzing

It is as simple as cake all that you need to do is to replace the FUZZ parameter at the end of the domain after the slash

wfuzz -w rockyou.txt https://hackingblogs.com/FUZZ

Status Code:-

So if you want to filter out certain response code you can use the following command

wfuzz -w rockyou.txt --sc 400,200,301 https://hackingblogs.com/FUZZ
What is Wfuzz?

This would return responses that have the following status code

Saving your Work

To save your work you can go and use the -f command or use the old-school method of writing down output via the arrow method ->

wfuzz -w rockyou.txt --sc 400,200,301 https://hackingblogs.com/FUZZ

Login Bruteforcing

So there may be a time when you will be required to brute-force login pages At that time you will be required to brute usernames and passwords so you will use the -d to post login data.
The Command that you will be utilizing will be:-

wfuzz -z file,rockyou.txt -d "log=FUZZ&pwd=FUZZ" https://hackingblogs.com/wordpress/wp-admin

Making Your Work Easy: Multiple Fuzzing

Suppose you want to fuzz the subdomains as well as the directories doing them twice might me time so instead you can use the following method of multiple fuzzing
FUZZ – Is the first FUZZ parameter
FUZ2Z – 2nd parameter
FUZ3Z – 3rd parameter

Command - wfuzz -w wordlist1.txt -w wordlist2.txt https://FUZ2Z.hackingblogs.code/FUZZ

Here the first -w is for the FUZZ parameter and the next -w is for the FUZ2Z paramter
