Linux is the preferred OS of choice for hackers around the world. There are several reasons for this:
Precise control – Linux provides complete control to the user over every aspect of the operating system right down to the kernel. This is very useful especially for pro-hackers who find Linux programs to have far more control and capabilities than in any other OS.
Security – another aspect which is a strong suite of Linux as it is known worldwide as the most secure OS.
Reliability – Third aspect is the high level of transparency provided by Linux which makes it valuable to hackers.
There are many different flavors of Linux available for hackers to choose from. Whether you are a beginner level hacker or a pro, there is a Linux version available for you. Some of the popular Linux versions used by hackers all over the world are:
Kali Linux – It is a free OS that has over 600 tools for penetration testing and security analytics. Kali follows an open-source model, all the code is available on Git and allowed for tweaking.
BackBox – The OS has its own software repository that provides the latest stable versions of various system & network analysis toolkits and also the most popular ethical hacking tools.
Parrot Security OS – It is a relatively new OS that is targeted for penetration testers and provides cloud-friendly environment with online anonymity and in-built encryption.
DEFT Linux – Digital Evidence & Forensics Toolkit, is a distribution made for computer forensics, with the purpose of running a live system without corrupting or tampering with the PC and its usual boot drives.
Samurai Web Testing Framework – This OS is developed with the sole purpose of penetration testing on the web and it comes as a virtual machine, supported by Virtualbox and VMware.
Some of the popular hacking tools that are a must in any hacker’s repertoire as follows:
NMap – Network Mapper provides network security details of the target network.
Lynis – module based tool that detects components on the OS and runs vulnerability scans for those components
WPScan – This free word press scanner can quickly detect any vulnerabilities in your WordPress blog.
Aircrack-ng – this is a set of tools for finding vulnerabilities in a Wi-Fi network and to test the Wi-Fi security.
There are also a huge set of tools such as Wireshark, Hydra, Metasploit Framework, Skipfish and others available for free and open source for hackers to use and hone their skills.
In my personal opinion first place in the best linux for hacking takes KALI LINUX. It is a ready-made system with the most common and effective tools for conducting penetration testing (hacking).
