The U.S. Secret Service has dismantled a massive hidden telecom network in the New York area, just as world leaders were gathering for the United Nations General Assembly (UNGA). The operation, which uncovered over 300 SIM servers and more than 100,000 SIM cards within a 35-mile radius of the United Nations, could have crippled cell towers, jammed 911 calls, and caused widespread communication blackouts during a critical time for the city.
Officials emphasize the system was capable of sending up to 30 million text messages per minute and was part of a broader investigation into threats targeting senior U.S. government officials
The network, described as a sophisticated and well-funded enterprise, functioned like a bank of mock cellphones, capable of generating mass calls and texts, overwhelming local networks, and masking encrypted communications.
The discovery was made during a Secret Service investigation into telecommunications threats, and while no direct plot to disrupt the UNGA has been uncovered, the potential for catastrophic consequences if the system had been activated is significant.
Forensic analysis of the 100,000 active SIM cards and associated communications is ongoing, with officials suspecting nation-state actors used the network to communicate with organized crime groups, cartels, and terrorist organizations.
Special Agent in Charge Matt McCool warned that the discovery highlights a new frontier of risk, with the potential for similar hidden networks to exist in other major U.S. cities. The U.S. Secret Service's director, Sean Curran, stated the takedown underscores the agency's commitment to preventing imminent threats to its protectees.
