Kali Linux is one of the most powerful and advanced OS (Operating System) for penetration testers and hackers for it’s pre-installed all the top penetration testing tools. It’s one of the best operating system for hackers.

Many people asked about which operating system is best for penetration testing and hacking activities like hacking wireless network passwords, reverse engineering tools, network sniffers, application hacking tools and other encrypting and spoofing hacking tools. So, I just writing this article to show you why most of the pentesters rely on the Kali Linux. How it’s one of the best operating system for hackers.

Kali Linux: Best Operating System for Hackers

Every hacker/researcher have their own choices but as a penetration tester, I have my own choice. Kali Linux is one of the best for me. Kali Linux and Windows 10 are the best because they are easier to use but because of their vast functionality, features and flexibility. But there’s some others you can give a try like Matriux Operating System, BackTrack, and knoppix. Matriux OS is just awesome.

Kali Linux is based on Debian Linux version, designed and developed by Offensive Security, specially powered with most of the powerful hacking tools for the penetration testing and hacking related activities. Kali Linux is designed to keep the beginners in mind, so it comes bundled with all the most common and powerful hacking tools.

When Kali Linux Was Released?

On 13th March, 2013, Kali Linux was released for the first time and within just few months, it became the most popular operating system for hackers and penetration testers. Kali Linux was born by it’s predecessor BackTrack, to make it specifically for the penetration testing and forensic activities.

Kali Linux Peneration Testing Tools

Kali Linux bundled with all the tools for different security forensics and penetration testing, which involves network and exploiting, network discovery, networks reconnaissance, web servers scanning, reverse engineering, scanning applications for vulnerabilities and IP address scanning as will. It comes up with all the best security tools for penetration testing, forensics and hacking tools like some of these below.

  • Metasploit Framework (Complete framework for Information gathering, analyzing web servers and applications security vulnerabilities and helps in penetration testing and IDS signature development.)
  • Nmap (Network Exploration Tool, Security Scanner & Port Scanner )
  • Aircrack-ng (All in One Wireless password cracking tool)
  • OWASP ZAP (An open source in depth web application security scanner)
  • Sqlmap (Sqlmap is a penetration testing tool used by the most of hackers to penetrate into websites using SQL loopholes. It detects and exploits SQL injection flaws automatically)
  • Wireshark (An open source packet sniffer and analyzer)
  • Reaver (WPS Wireless Brute Force cracking tool)
  • John the Ripper (A full pack of Password cracking)
  • Hydra (Brute Force Password cracking tool)
  • SET (The Social Engineer Toolkit)
  • Hashcat (It’s the world’s fastest most powerful and advanced password recovery tool)
  • Armitage (Metasploit Framework’s GUI front end designed with JAVA)
  • Burp Suite (Web Application Security GUI scanner)
  • Ettercap (MitM (Man in the Middle) attacks Suite)
  • Cisco Global Exploiter (Cisco Networking equipment for fast testing and Exploiting Vulnerabilities)
  • BeEf Framework (Also known as Browser Exploitation Framework, for web browser vulnerabilities)
  • SSLStrip (SSL Strip Tool for attacking the SSL enabled applications)
  • Kismet (Wireless Networks detector, sniffer, and intrusion detection system)
  • Foremost (Foremost is used recover deleted or lost files based on their headers, internal data structures and footers)
  • Maltego (An open source forensics and intelligence tool)
  • And hundreds of more…
