Secret Service Dismantles Covert Telecom Network Near UN, Citing Imminent Threat to NYC Cell Service

Early forensics on the seized servers point to communications tied to nation-state actors.

Overview

  • Agents seized more than 300 SIM servers and about 100,000 SIM cards across multiple sites within 35 miles of the United Nations headquarters.
  • Officials say the system could disable cell towers, jam 911 calls, and overwhelm networks, with capacity estimated at up to 30 million text messages per minute.
  • The takedown grew out of a spring investigation into telecommunications threats directed at senior U.S. officials.
  • Preliminary analysis indicates the network carried cellular communications between nation-state threat actors and individuals known to federal law enforcement, with attribution still under review.
  • No arrests have been announced, the equipment has been removed, and a multiagency probe continues with HSI, DOJ, ODNI and the NYPD.
