I told him, this was the 'hacker' of the 80s, read how he managed to 'hack' all these places. My father replied, "I'm pretty sure I won't understand anything he would do". Me, "Just give it a chance, you'll be surprised"
When he gave the book back, I asked my father if anything Kevin did my father wouldn't have understood. My father said, "I understood everything he did". I asked, "Now, when you get a call from someone you don't know claiming to be an authority figure, what do you do?". Father: "Hang up"
He called someone, claimed to be an authority, knew the lingo, asked for help and time was the critical.
Someone calls your parents and claims to be an authority figure, that there is a crisis, and they must act now.
