the admin was very surprised and the admins asked me how i did it. i did point out that the greatest of their weaknesses were that they left the computers without signing out, weak password choosing and depending too much on the ready made tools out of the box. from that day on they hired some penetration testers to audit the school network.
this is just but one real life example on how most of the admins are ignorant, dependent on tools and lazy.
stay safe and don't depend on the programs out of the box.
