The Secret Service has found a vast and stunning network of more than 100,000 SIM cards and 300 SIM servers – the largest seizure ever of such devices by the Secret Service – all concentrated within 35 miles of New York City.

The servers could be commanded remotely to create massive amounts of phone traffic in a stealthy and unceasing operation that switched out SIM cards quickly to keep federal law enforcement off its trail. #CNN #News
