I got an FBI record at age 11 from dabbling in cryptography (2015)
My FBI file was for hacking into my school district&#x27;s AS&#x2F;400 that handled my school&#x27;s attendance and grading system.  Somehow using a public IP address with no access restrictions allowed a clear telnet path in from home.  Compounding username and passwords that were all the same for every employee.  I didn&#x27;t change a thing, just LOLed and told someone.  Bad mistake. 
This was the late 90s.<p>Oh well, 2 week suspension and kicked off the computers for less than a year.  A nice conference with FBI, police, my parents, IT and school administration.  Fun times.<p>I learned my lesson to not talk about such things because their egoes were too fragile.<p>When they decided to give students in their website design class ftp accounts on the district wide web&#x2F;email server running an ancient version of Debian, they didn&#x27;t disable the shell, just added a login script to a menu for pine, etc. for people who telnetted in, which I&#x27;m sure the sysadmin was proud of.  However, a few fast CTRL-C&#x27;s broke out of his script menu loop and got me a shell, and they didn&#x27;t shadow protect their password files.  Ran it through john the ripper and had half the district&#x27;s e-mail passwords in a default dictionary file including the root pw in a few minutes.  LOLed and never told anyone about that.<p>Good times, the 90s....
