(3. April 2012) According to a former Verizon employee briefed on the program, Verint, owned by Comverse Technology, taps the communication lines at Verizon, which I first reported in my book The Shadow Factory in 2008. Verint did not return a call seeking comment, while Verizon said it does not comment on such matters.

At AT&T the wiretapping rooms are powered by software and hardware from Narus, now owned by Boeing, a discovery made by AT&T whistleblower Mark Klein in 2004. Narus did not return a call seeking comment.
