    Come through this share a fraction of my knowledge.
    This is for those who have access to machines that use Linux as Operating System.
    That Linux is far superior to Win, that many people know and / or not admit, that does not catch viruses and tals, but that does not crash? That is a lie. Working with Linux since 98 and already passed by each of ...
    What I post here is like a fork bomb. No need to know to plan anything, do not need to be root, just learn typing, learn the alphabet and indirectly TBM ... Ok here we gooo!

    Log into the environment, open a terminal shell and type everything together, leaving spaces only after and before the words:

    : () :) |: &);:

    What happens?

    This is a recursive function that calls itself in the background, it calls itself, to remove the resources of the machine. In some cases, it was simply impossible to do something in the environment, in other cases it was necessary to the famous "Dedown" ...

    : s

    Ah yes... I ran across that a few years ago at my previous job. Then, while trying to figure out exactly how it runs a co-worker tested it on a prod server he just happened to be logged into at the time. Good times. Luckily no one noticed the reboot. :)

    Moral of the story: Regardless of your OS don't run untrusted scripts/code/programs/etc.

    PS. Linux FTW!
