often want to install a program or want to configure a Linux service in our turn to internet to see if we find a howto to help us, many even sometimes directly copied and pasted the commands that appear in these guides directly to your computer executing those instructions and commands. But what happens if this is a malicious command?
see some of these commands:
# mkfs.ext3 / dev / sda This command formats the hard drive.
# :(){: This command will move all the folders and files in / dev / null Elymian pitch these these files permanently. Well I hope each of you to analyze and review what it does well when we turn to these guidelines, a recommendation is to have a virtual machine to test before. I invite you to comment if you know other commands as there are surely more than these 4 that I mentioned today. xJlara
