The Secret Service dismantled a network of more than 300 SIM servers and 100,000 SIM cards in the New York-area that were capable of crippling telecom systems and carrying out anonymous telephonic attacks, disrupting the threat before world leaders arrived for the UN General Assembly.

NEW YORK – The U.S. Secret Service 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, which represented an imminent threat to the agency’s protective operations.
This protective intelligence investigation led to the discovery of more than 300 co-located SIM servers and 100,000 SIM cards across multiple sites.
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.
“The potential for disruption to our country’s telecommunications posed by this network of devices cannot be overstated,” said U.S. Secret Service Director Sean Curran. “The U.S. Secret Service’s 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.”
These devices were concentrated within 35 miles of the global meeting of the United Nations General Assembly now underway in New York City. 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. The U.S. Secret Service’s Advanced Threat Interdiction Unit, a new section of the agency dedicated to disrupting the most significant and imminent threats to our protectees, is conducting this investigation. This investigation is currently ongoing.
The Department of Homeland Security’s Homeland Security Investigations, the Department of Justice, the Office of the Director of National Intelligence and the NYPD, as well as other state and local law enforcement partners, provided valuable technical advice and assistance in support of this investigation.
This is an ongoing investigation.

The U.S. Secret Service has announced that, following a monthlong investigation, it has carried out an operation which resulted in the dismantling of a network consisting of more than 300 SIM Servers and 100,000 SIM Cards at multiple sites across New York and New York City, all within a 35-mile radius of this week’s United Nations General Assembly.
According to officials, the network could interfere with emergency response services, conduct encrypted communication, jam cellular networks in New York, as well as disrupt official communication from and eavesdrop on the U.N. General Assembly, capable of sending over thirty-million text messages per minute, anonymously. The official said the agency had never before seen such an extensive operation.
The Secret Service believes that the scale of the equipment discovered suggests the network could be part of a nation’s surveillance operation, with initial analysis of the data on some of the SIM Cards having identified ties to at least one foreign nation, as well as links to criminals, including the members of Cartels, already known to be operating in the United States. Cybersecurity experts have stated that only a handful of countries could pull off such an operation, including Russia, China and Israel.

The US Secret Service confirmed dismantling 300+ SIM servers and 100,000+ SIM cards in NY area, capable of disabling cell towers, jamming 911, and sending 30M anonymous texts/min. Found via probe into threats to officials; no direct UNGA plot identified, but proximity raises concerns.
Early analysis links to nation-state actors and cartels, per official release and reports (NYT, NY Post). Experts speculate Russia, China, or Israel involvement for espionage, but unconfirmed. Investigation ongoing; similar setups possible elsewhere.
