  2. Thanks soooo much for giving such a secret information for hacking . I have just started hacking and i am sure that i will become a hacker today from this information. Thanks So much so much

  3. Interesting article about operating system of hacking..

    you define very well all information.

  4. What about Raspberry PI, well it is not an operating system in general, but there is a downloadable iso image for it, so it still counts, right?

  5. Kali Linux is for posers. Not only that it’s a pretty crappy OS despite being Debian. Half the garbage it comes with is “bloat ware” in my opinion. Get Ubuntu and install what you need as you go. I run most of the same tools Kali uses but with Ubuntu. And honestly… I’e ran into less configuration issues using the same tools, on Ubuntu.


  6. I want to learn computer science and computer forensics I want to be an artist in the world of coding, algorithms etc…. Can anyone help me
