# Hacking TechTV

Foo tells his story about how he got into TechTV using some old skool hacking techniques.

I knew that the phone system used 415-355-….The last four digits were the extensions to each and every person at TechTV. Now, the first number of the last four digits would always either be a 4 or a 5. So now I knew 415-355-4/5…From there it was a guessing game, I tried every possible combination.
