Overview

  • Agents seized more than 300 SIM-server devices and over 100,000 SIM cards from multiple sites roughly 56 kilometers from U.N. headquarters.
  • Officials say the setup could overwhelm cell towers, block 911 calls, and push up to 30 million text messages per minute to crash networks.
  • The discovery in August stemmed from a broader Secret Service inquiry launched in the spring after anonymous threats to senior U.S. officials.
  • The investigation now involves the Secret Service, NYPD, Justice Department, Homeland Security Investigations, and the Office of the Director of National Intelligence.
  • Investigators are probing possible ties to state-backed operators and caution that similar clandestine networks may exist elsewhere in the United States.
