Matthew Weigman

Fascinating story of a 16-year-old blind phone phreaker.

One afternoon, not long after Proulx was swatted, Weigman came home to find his mother talking to what sounded like a middle-aged male. The man introduced himself as Special Agent Allyn Lynd of the FBI's cyber squad in Dallas, which investigates hacking and other computer crimes. A West Point grad, Lynd had spent 10 years combating phreaks and hackers. Now, with Proulx's cooperation, he was aiming to take down Stuart Rosoff and the Wrecking Crew — and he wanted Weigman's help.

Lynd explained that Rosoff, Roberson and other party-liners were being investigated in a swatting conspiracy. Because Weigman was a minor, however, he would not be charged -- as long as he cooperated with the authorities. Realizing that this was a chance to turn his life around, Weigman confessed his role in the phone assaults.

Weigman's auditory skills had always been central to his exploits, the means by which he manipulated the phone system. Now he gave Lynd a first-hand display of his powers. At one point during the visit, Lynd's cellphone rang. "I can't talk to you right now," the agent told the caller. "I'm out doing something." When he hung up, Weigman turned to him from across the room. "Oh," the kid asked, "is that Billy Smith from Verizon?"

Lynd was stunned. William Smith was a fraud investigator with Verizon who had been working with him on the swatting case. Weigman not only knew all about the man and his role in the investigation, but he had identified Smith simply by hearing his Southern-accented voice on the cellphone -- a sound which would have been inaudible to anyone else in the room. Weigman then shocked Lynd again, rattling off the names of a host of investigators working for other phone companies. Matt, it turned out, had spent weeks identifying phone-company employees, gaining their trust and obtaining confidential information about the FBI investigation against him. Even the phone account in his house, he revealed to Lynd, had been opened under the name of a telephone-company investigator. Lynd had rarely seen anything like it -- even from cyber gangs who tried to hack into systems at the White House and the FBI. "Weigman flabbergasted me," he later testified.
