    Take down the image of the shadow file, and immediately change ALL passwords on that system.

    NEVER reveal the contents of the shadow file, it has all your passwords in it. They are encrypted, but even the encrypted versions are not safe to share because it opens you up to brute force cracking attempts. By posting that image you have told the entire internet WAY too much about your passwords.

    The contents of these files is explained in the man pages for them, try these commands for some good reading:
    man -s5 passwd
    man -s5 shadow
    man -s5 group
