The U.S. Secret Service has successfully dismantled an extensive and sophisticated hidden telecommunications network near the United Nations headquarters in New York City, averting a potentially catastrophic cellular blackout during the recent gathering of nearly 150 world leaders for the U.N. General Assembly.

This massive operation, involving more than 300 SIM servers packed with over 100,000 active SIM cards, was discovered within 35 miles of the UN and represents one of the most significant communication threats ever uncovered on U.S. soil. Investigators warn that the system had the capability to cripple cell towers, jam 911 emergency calls, and overwhelm networks, plunging a city reliant on connectivity for daily life and critical emergency response into chaos.

The takedown occurred quietly while foreign leaders filled Manhattan hotels, underscoring a new frontier of risk targeting the invisible infrastructure vital to modern urban centers. The discovery was part of a broader Secret Service investigation into telecom threats against senior government officials. The servers functioned as mock cellphones, designed to generate mass calls and texts, flood local networks, and facilitate encrypted communications for criminal organizations.

Special Agent Matt McCool, in charge of the Secret Service’s New York field office, emphasized the severe potential impact. “It can’t be understated what this system is capable of doing,” McCool stated, noting that a coordinated attack during an event like the UNGA could have been “catastrophic to the city.”

While officials have not uncovered a direct plot against the UN General Assembly, forensic analysis is underway. Agents suspect nation-state actors leveraged the system to communicate with organized crime groups, cartels, and terrorist organizations. The investigation into the 100,000 active SIM cards, including call and text data, is expected to be a lengthy process.

The operation was described as a well-funded, highly organized enterprise, costing millions in hardware and SIM cards, with the capacity to send up to 30 million text messages per minute. Secret Service Director Sean Curran highlighted the agency’s preventative mission, stating, “This investigation makes it clear to potential bad actors that imminent threats to our protectees will be immediately investigated, tracked down and dismantled.”

Officials drew parallels to cellular blackouts experienced after the 9/11 attacks and the Boston Marathon bombing, warning that this network could have forced similar shutdowns at will. The Secret Service also cautioned that similar hidden networks might exist in other U.S. cities, necessitating ongoing vigilance.
