Unlocking the Power: Top Free Hacking Tools for Ethical Hackers 2023

free hacking tools

When I have started to learn in 2011, the single question was stuck in my mind always what are the free hacking tools used by top hackers worldwide. At that time I have been working as a Linux System Administrator, and have good command over Linux. So I chose the Backtrack operating system to start hacking.

Today I can understand your condition if you are learning how to hack and still confused about hacking tools used by pro hacker and penetration tester then this post is relevant for you.

Free Hacking tools for Information Gathering

#1 OSINT Framework

OSINT Framework This is not a tool but framework focused on gathering information using different tools available open source (over internet). The intention is to help people find free OSINT resources. Some of the sites included might require registration or offer more data for $$$, but you should be able to get at least a portion of the available information for no cost.


SHODAN: Shodan also is not a tool, it is a search engine that lets the user find specific types of computers (webcams, routers, servers, etc.) connected to the internet using a variety of filters. Some have also described it as a search engine of service banners, which are metadata that the server sends back to the client.[1] This can be information about the server software, what options the service supports, a welcome message or anything else that the client can find out before interacting with the server.

#3 Check User Name

CheckUserName: It is an online service that helps hacker to check usernames more than over 170 social networks. This is especially useful if Hacker is looking for social media accounts with a specific username and helpful The penetration tester for running an investigation to determine the usage of the same username on different social networks.

#4 Google Dorks

GOOGLE DORKS: Hacker never forgets to gather useful information using the search engine Google. Google hacking is a technique to get information hidden in a deep search engine Database. Google Hacking Database is the collection of google dorks.

John supports different cracking modes and understands many ciphertext formats, like several DES variants, MD5 and blowfish. It can also be used to extract AFS and Windows NT passwords.

Documentation : https://www.openwall.com/john/doc/

#27 Hashcat

According to official website Hashcat is the world’s fastest CPU-based password recovery tool.

While it’s not as fast as its GPU counterpart oclHashcat, large lists can be easily split in half with a good dictionary and a bit of knowledge of the command switches.

Hashcat was written somewhere in the middle of 2009. Yes, there were already close-to-perfect working tools supporting rule-based attacks like “PasswordsPro”, “John The Ripper”. However for some unknown reason, both of them did not support multi-threading. That was the only reason to write Hashcat: To make use of the multiple cores of modern CPUs.

Granted, that was not 100% correct. John the Ripper already supported MPI using a patch, but at that time it worked only for  attack. There was no solution available to crack plain MD5 which supports MPI using rule-based attacks.

#30 FcrackZip

fcrackzip searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better.

Have you ever mis-typed a password for unzip? Unzip reacted pretty fast with ´incorrect password´, without decrypting the whole file. While the encryption algorithm used by zip is relatively secure, PK made cracking easy by providing hooks for very fast password-checking, directly in the zip file. Understanding these is crucial to zip password cracking.

BeEF is short for The Browser Exploitation Framework. It is a penetration testing tool that focuses on the web browser.

Amid growing concerns about web-borne attacks against clients, including mobile clients, BeEF allows the professional penetration tester to assess the actual security posture of a target environment by using client-side attack vectors. Unlike other security frameworks, BeEF looks past the hardened network perimeter and client system, and examines exploitability within the context of the one open door: the web browser.

BeEF will hook one or more web browsers and use them as beachheads for launching directed command modules and further attacks against the system from within the browser context.
