Linux has always been a favorite operating system for hackers because it allows them the control they require to do strange and ingenious things. The power and flexibility of Linux make it the hacker’s playground. They use it, learn it, and understand it intimately. And that means that if there’s an insecurity, they’re going to find it.
In this article, we’ll look at the 10 best Linux-based operating systems for ethical hackers and penetration testers.
Top 10 favorite operating system of hackers
