literally ran a basic wardialer in my area code and had guest access to multiple government systems. I felt like matthew broderick would have been so proud.

I never got anywhere but it freaked my parents out they were not proud like i had been expecting at all.

Never actually messed around with anything besides figuring out the no password guest accounts so not really thrilling but it was super easy to get access.

Also when email was first a thing you could just telnet to port 25 on a server and write raw SMTP messages and most servers would just accept them. You would say yes this message is coming from [email protected] and it would say sure thing!

That's still true, I was explaining this at work to the sysadmin that they should be careful and they said our email addresses couldn't be spoofed, so I demonstrated it with his address. Spooked him a bit.
