Exploding the Phone is the result of five years of extensive research by author Phil Lapsley. Much before the advent of smartphones, laptops and internet, the pre-digital telephone system was the most used. The book contains some historical discussion of the development of the phone system. Mostly it comprises of the stories of the young men called the phreaks who figured out the vulnerabilities and flaws of the telephone system. They further began to explore and exploit them in the 1960s and early 1970s. There is also the story of a big phone company who desperately wanted a monopoly, and about the war between the FBI, the phone company and the phreaks. A fascinating technical bestseller about the history of the telephone system and tales of phreakers and hackers.
