About the Israeli spy ring? It was something I read a long time ago.
What I remember also is they (israeli companies) owned, not just the billing company for US telcos, but also the company that provided the wiretapping devices for the USG, so they had, not just the info on who called who and when (including businesses and gov agencies), but also through the more than certainly backdoors into those wiretapping devices, the ability to spy on those conversations, as well as early warning about US wiretapping targets.
These are publicly acknowledged facts, and widely available info:
