I'm about half way through Ghost in the Wires and this sounds exactly like something he'd do. "Hi, this is so-and-so and I'm with this-and-that. Could you send me a copy of the source code? I'm all over your phone line" The book is a continuous stream of anecdotes like this. Love it.
Yep so good and the ‘ring this number to prove I am real’ was a walk in the park for him.
