The U.S. Secret Service said Tuesday that it "dismantled a network of electronic devices located throughout the New York tristate area that were used to conduct multiple telecommunications-related threats directed towards senior U.S. government officials."The devices were concentrated within 35 miles of the ongoing United Nations General Assembly meeting in New York City, it added."This protective intelligence investigation led to the discovery of more than 300 co-located SIM servers and 100,000 SIM cards across multiple sites," the Secret Service said in a statement. "In addition to carrying out anonymous telephonic threats, these devices could be used to conduct a wide range of telecommunications attacks. This includes disabling cell phone towers, enabling denial of services attacks and facilitating anonymous, encrypted communication between potential threat actors and criminal enterprises.""While forensic examination of these devices is ongoing, early analysis indicates cellular communications between nation-state threat actors and individuals that are known to federal law enforcement," it also said.The Department of Homeland Securitys Homeland Security Investigations, the Department of Justice, the Office of the Director of National Intelligence, the New York Police Department and other state and local law enforcement partners are assisting with the investigation."The potential for disruption to our countrys telecommunications posed by this network of devices cannot be overstated," U.S. Secret Service Director Sean Curran said. "The U.S. Secret Services protective mission is all about prevention, and this investigation makes it clear to potential bad actors that imminent threats to our protectees will be immediately investigated, tracked down and dismantled."The Secret Service also said: "Given the timing, location and potential for significant disruption to New York telecommunications posed by these devices, the agency moved quickly to disrupt this network."This is a developing story.
