How to Brute Force login page using wfuzz?
Before starting to hack the target website, we need to know some basic commands of the wfuzz tool. For that, we can open its help page. Let’s follow the below command.
wfuzz -h
Information gathering is a crucial phase for website hacking. It might be a challenging task to hack a website without information gathering. We spent more time gathering information about the target website, such as name, phone, email, etc. After that, we generated password wordlists using the crunch tool. If you don’t know how to make password wordlists, first, read the below blog.
We opened the target website in our browser that looks pretty charming. Remember, we have used our website for demo purposes. It is only a virtual environment, Don’t try to hack this website.
We will scan the website admin page, for that dirbuster is a good tool that can be used to perform brute force attacks on each website. It could be a comfortable tool to obtain hidden directory, URI, robots.txt file, htacces file, etc.
Excellent! We have discovered the admin page of the target website.
We noticed a suspicious file extension developed in PHP language. I think that there is more malicious code available on the Internet. It depends on the PHP version. Let’s enter some malicious code on the target website.
I found malicious code is not working. Let’s intercept post requests by entering the default username&password on the target website. For that, we will use the Burp suite tool. Burp Suite is one of the most popular penetration testing and bug bounty tools. It comes both free and paid, But the paid version is more reliable compare to free. Burp Suite Community Edition comes pre-installed in Kali Linux.
We have mentioned its essential parameter often used to bypass the login page.
We have obtained the post request data of the target website. The next step! We will append to all credentials with the wfuzz Tool. Let’s follow the below image.
wfuzz -c -u http://pentestblog/cdn-cgi/login/index.php -d 'username=admin&password=subscribe' -w --hc 200
As you know, our mission is to hack the pentestblog website. For that, we need a username & password. Wfuzz tool allows an attacker to use the password wordlists during the brute force attack mentioned above.
Username: admin
Password: password_disctionary.txt
wfuzz -c -u http://pentestblog/cdn-cgi/login/index.php -d 'username=admin&password=FUZZ' -w password_disctionary.txt --hc 200
Excellent! We have discovered the username & password of the target website.
Username: admin
Password: MEGACORP_4dmln!!
Let’s log in with valid credentials.
We have logged in target website with valid credentials. “So that” we could enter in website server.
