The US Secret Service has dismantled a network of SIM farms in and around New York City it claims was behind multiple incidents targeting senior government officials and had enough power to disrupt entire cellular networks.

The network – or at least the parts the Secret Service has discovered – was massive, consisting of more than 300 colocated SIM servers, controlling more than 100,000 SIM cards, set up at multiple locations. All of the facilities the Secret Service discovered were located throughout the New York Tri-state area (NY, New Jersey, and Connecticut) but all within 35 miles of the UN headquarters building in NYC.
