A massive telecom threat counterfeited in New York, America.

Sept 2025 : As 150+ world leaders assembled at Manhattan, New York City for the United Nation’s General Assembly, the U.S. Secret Service was quietly dismantling a massive hidden telecom network across the New York area — a system investigators say could have crippled cell towers, jammed the emergency 911 services and could have crippled the networks chaotic.

The plot made up of more than 300 SIM servers packed with over 100,000 SIM cards and clustered within 35 miles of the United Nations, represents one of the most sweeping communications threats uncovered on U.S. soil. Investigators warn the system could have blacked out cellular service in a city that relies on it not only for daily life but for emergency response and counterterrorism.

As the New York City is occupied with foreign leaders, and midtown hotels overbooked, officials say the attempted perpetuality highlights a new frontier of risk: plots aimed at the invisible infrastructure that keeps a modern city connected. The network was uncovered as part of a broader Secret Service investigation into telecommunications threats targeting senior government officials, according to investigators. Spread across multiple sites, the servers functioned like banks of mock cellphones, able to generate mass calls and texts, overwhelm local networks and mask encrypted communications criminals, officials said.

According to Matt McCool, the special agent in charge of the Secret Service’s New York field office, “It can’t be understated what this system is capable of doing. It can take down cell towers, so then no longer can people communicate. You can’t text message, you can’t use your cell phone. And if you coupled that with some sort of other event associated with UNGA, you know, use your imagination there, it could be catastrophic to the city”. Officials said they haven’t uncovered a direct plot to disrupt the U.N. General Assembly and note there are no known credible threats to New York City.

Forensic analysis is still in its early stages, but agents believe nation-state actors, perpetrators from particular countries, used the system to send encrypted messages to organised crime groups, cartels and terrorist organisations, McCool said. Authorities have not disclosed details on the specific government or criminal groups tied to the network at this point. “We need to do forensics on 100,000 cell phones, essentially all the phone calls, all the text messages, anything to do with communications, see where those numbers end up”, McCool said, noting that the process will take time.

When agents entered the sites, they found rows of servers and shelves stacked with SIM cards. More than 100,000 were already active, investigators said, but there were also large numbers waiting to be deployed, evidence that operators were preparing to double or even triple the network’s capacity, McCool said. He described it as a well-funded, highly organised enterprise, one that cost millions of dollars in hardware and SIM cards alone. The operation had the capability of sending up to 30 million text messages a minute, McCool said.

“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 citizens will be immediately investigated, tracked down and dismantled”, the agency’s director, Sean Curran, said in a statement.

Officials also warned of the havoc the network could have caused if left intact. McCool compared the potential impact to the cellular blackouts that followed the September 11 attacks and the Boston Marathon bombing, when networks collapsed under strain. In this case, he said, attackers would have been able to force that kind of shutdown at a time of their choosing. “Could there be others?” said McCool “It’d be unwise to think that there’s no other networks out there being made in other cities in the United States”.
