Unlocking Ma Bell: How phone phreaks came to be

Imagine a day when it cost an arm and a leg to use the phone, especially for long-distance calls. Then imagine that buried deep within the telephone network infrastructure was a flaw -- a hole that allowed those who were aware of it, and capable of exploiting it, to make all the free calls they want.

These days, phone calls are free -- or nearly so -- and hackers put their energies into computer networks, jailbreaking iPhones, and other more modern pursuits. But back in the 1950s and 1960s, a new group of people emerged, people who were fascinated by … Read more

The results were better than expected. Analysts, on average, forecast a per-share … Read more
