12 Most Used Operating systems by hackers

Hey Guys! Welcome 

➤Here Are The Top 12 Operating Systems Used By Both Ethical And Black Hat Hackers

Penetration testing is becoming increasingly important for organizations of all sizes, as security breaches continue to grow both in frequency and in the amount of damage they cause. Hackers are always on the lookout for vulnerabilities in a computer system or network that can be easily breached and exploited.
There are some hackers who hack for the pure pleasure of hacking, while there are some who identify system vulnerabilities and access points for penetration, and prevent unwanted access to network and information systems and in return get lucratively paid for doing so. Then, there are those hackers who just want to exploit, embarrass and expose.
So, which operating systems do you think hackers enjoy exploiting the most? Since most of the operating systems for hacking is based on Linux kernel, which means that Linux is always the favorite operating system for hackers.

In this article, we have listed top 10 open source hacking operating systems for ethical hacking and penetration testing.
1.) Kali Linux

Developed and funded by Offensive Security Ltd. as the rewrite of BackTrack, Kali Linux distro is one of the best and favourite operating systems of hackers. Kali Linux is a Debian-based Linux distribution aimed at advanced Penetration Testing and Security Auditing. It contains several hundred tools which are geared towards various information security tasks, such as Penetration Testing, Security research, Computer Forensics and Reverse Engineering.
Kali Linux is an open source project that is installable. However, the general concept is to make use of it from the live session, running all sorts of probes and tests and investigations against network targets and offline local storage. It’s geared up both with Windows and Linux-oriented tools. It also supports Wireless 802.11 frame injection, one-click MANA Evil Access Point setups, HID keyboard (Teensy like attacks), as well as Bad USB MITM attacks.
Further, Kali Linux updates its tools, and it is available for different platforms like VMWare, ARM and many more. Also, Kali is pre-installed with the best programs and security tools like Hydra (login cracker), Nmap (port analyzer), Wireshark (data packet analyzer), John the Ripper (password cracking tool) and Metasploit Framework (exploit code developing tool), and other tools that make it different from the other penetration testing operating systems.

2. )Parrot Security OS

Developed by the Frozenbox Team, Parrot Security OS (or ParrotSec) is a GNU/LINUX distribution based on Debian with a focus on computer security is another hackers’ favorite operating system. It is designed for penetration testing (computer security), vulnerability assessment and mitigation, computer forensics and anonymous web browsing.
Parrot uses Kali repositories in order to take latest updates for almost all the tools, but it also has its own dedicated repository where all the custom packets are kept. This is why this distro is not just a simple Kali “mod” but entire new concept which relies on Kali’s tool repositories. As such, it introduces a lot of new features and different developing choices. Parrot uses MATE as a Desktop Environment. Lightweight and powerful interface is derived from famous Gnome 2, and thanks to FrozenBox’s highly customizable captivating icons, ad-hoc themes and wallpapers.
The project is certified to run over machines which have 265MB of RAM at least and it is suitable to both 32-bit (i386) and 64-bit (amd64), with a special edition it works on old 32-bit machines (486). Moreover, the project is available for armel and armhf architectures. It even offers an edition (both 32-bit and 64-bit) developed for servers only to carry out cloud pentesting.

3. )BackBox

BackBox is a penetration test and security assessment oriented Ubuntu-based Linux distribution providing a network and informatic systems analysis toolkit. BackBox desktop environment includes a complete set of tools required for ethical hacking and security testing.
BackBox is lightweight OS and requires less hardware specification. The main aim of BackBox is providing an alternative, highly customizable and well performing system. It runs a desktop environment based on the lightweight Xfce window manager, which makes it standard and easy to use. It includes some of the most used security and analysis Linux tools, aiming for a wide spread of goals, ranging from web application analysis to network analysis, from stress tests to sniffing, also including vulnerability assessment, computer forensic analysis and exploitation.
BackBox has its own software repositories, which is always kept updated to the latest stable version of the most used and best known ethical hacking tools. The integration and development of new tools in the distribution follows the open source community, particularly the Debian Free Software Guidelines criteria.

4.) DEFT Linux

DEFT (Digital Evidence and Forensic Toolkit) is an open source distribution of Linux built around the DART (Digital Advanced Response Toolkit) software and based on the Ubuntu operating system. It is a distribution made for Computer Forensics, with the purpose of running live on systems without tampering or corrupting devices (hard disks, pendrives, etc…) connected to the PC where the boot process takes place. It is loaded with the best free and open source applications dedicated to incident response, cyber intelligence, computer forensics, and designed for use by the military, law enforcement, private security professional and IT auditors.

5.)Caine

Caine is an Ubuntu-based security-focused distro that is available as a live disk. It stands for Computer Aided Investigation Environment and can also be run from the hard disk after installation. This Linux distro comes with a wide range of tools to help you in system forensics.

Caine comes with a large number of database, memory, forensics, and network analysis applications. This distro for ethical hacking also features common applications like web browsers, email clients, document editors etc. for usual computing purposes.

6.) Samurai Web Testing Framework

The Samurai Web Testing Framework is a virtual machine that is supported on VirtualBox and VMWare, and has been pre-configured to function as a web pen-testing environment. The VM contains the best of the open source and free tools that focus on testing and attacking websites. It also includes many other tools, such as WebScarab, ratproxy, w3af, Burp Suite, and BeEF. It’s often called the best operating system for Web Penetration Testing.

7.) Live Hacking OS


Live Hacking DVD is a Linux distribution filled with tools and utilities for ethical hacking, penetration testing and countermeasure verification. Based on Ubuntu, this ‘Live DVD” runs directly from the DVD and doesn’t require installation on your hard-drive. Once booted, you can use the included tools to test, check, ethically hack and perform penetration tests on your own network to ensure that it is secure from outside intruders.
The distribution comes in two forms. A full Linux desktop including a graphical user interface (GNOME) and applications like Firefox along with tools and utilities for DNS enumeration, reconnaissance, foot-printing, password cracking and network sniffing. For greater accessibility, there is a Live Hacking menu to help you quickly find and launch the tools.
The second variation is the Live Hacking Mini CD, which is command line only. However, this doesn’t detract from the power of the tools and utilities included as most of the penetration testing and ethical hacking tools are command line tools. The included /lh directory has symbolic links to the different tools included. It also requires very less hardware requirements.
For example, a fast Pentium 3 or any Pentium 4 class processor (or greater) is sufficient. For the desktop version, 512MB of memory is required with 1GB recommended. Further, the command line version just needs 128MB of memory.
