It is well-known that the two largest American telecom companies AT&T and Verizon collaborated with the US government to allow illegal eavesdropping on their customers. The known uses to which information obtained this way has been put include building the government's massive secret "watch lists," and "no-fly lists" and even, Bamford suggests, to deny Small Business Administration loans to citizens or reject their children's applications to military colleges.
What is less well-known is that AT&T and Verizon handed "the bugging of their entire networks -- carrying billions of American communications every day" to two companies founded in Israel. Verint and Narus, as they are called, are "superintrusive -- conducting mass surveillance on both international and domestic communications 24/7," and sifting traffic at "key Internet gateways" around the US.
Virtually all US voice and data communications and much from the rest of the world can be remotely accessed by these companies in Israel, which Bamford describes as "the eavesdropping capital of the world." Although there is no way to prove cooperation, Bamford writes that "the greatest potential beneficiaries of this marriage between the Israeli eavesdroppers and America's increasingly centralized telecom grid are Israel's intelligence agencies."
Israel's spy agencies have long had a revolving-door relationship with Verint and Narus and other Israeli military-security firms.
