Secret Service Dismantles Covert SIM-Server Network Near UN That Could Cripple NYC Cell Service

Investigators are combing through 100,000 seized SIM cards to determine the network’s purpose.

Overview

  • More than 300 SIM servers and over 100,000 SIM cards were seized across multiple sites within 35 miles of U.N. headquarters, including abandoned apartment buildings.
  • Officials said the system could disable cell towers, jam 911, launch denial-of-service attacks, and send up to 30 million text messages per minute.
  • The investigation began after spring telephonic threats to senior U.S. officials, with the seized hardware used to route anonymous communications tied to those threats.
  • Early analysis indicates communications between foreign actors and individuals known to federal law enforcement, with possible links to organized crime and cartels, though no countries were named.
  • No arrests have been announced as a multiagency probe led by the Secret Service and HSI continues, and officials report no specific plot against the U.N. General Assembly or credible threat to New York City.
