Yes excellent Book.

The way the hacker Got into the system was very interesting.

Before reading the book, I had found something similar (not hacking)

In a 1966 mainFrame computer I was working on in 1979. On the F-4 Fight Simulators. The problem was with the RAWS Electronic Warfar radar system. I was asked to install a new version of the Aircraft box in the sim, and told I should see no difference. As the system was turned on, it would shut itself off as the display was about to come on. The problem was in a Ring Timer within the software. And was not allowing sufficient time for the system to come up. I went in to the memory core, changed (doubled the timing) and it worked.

I was asked by my Branch Chief and supervisor to go over to the commanders office, I had no idea why, I thought I was in trouble.

I got a 6 page letter of accommodation, from different Officers down the chain of command to the guy who had asked me to swap AirCraft Black Boxes in the Sim.. My commander Added his letter on top of the others, his letter with, "Rarely have I seen as a letter more impressive as this"


Yes those were the days, that Main Frame built in 1966 had 8K of core memory and it was the size of two shoe boxes. LOL.

The Hard drive was called a Drum and stood 3 ft tall and and 2 feet across.

Now you can fit 6TB on a Portable Harddrive. Or 256GB on a Thumb Drive. Moore's Law hard at work for decades.

Today's Smartphone makes the futuristic Star Trek Communicator look like a tinker toy. We've come a long way baby.

Glad you enjoyed the nostalgia trip multivalue, and as stated, it's still a Book Cyber Security Professionals should read today.
But written so anyone can read and understand. I know I could not stop reading it once I started.
