- The US Secret Service dismantles a network of SIM servers and 100,000 SIM cards used for telecom attacks in New York area.
- Devices were found within 35 miles of the UN General Assembly location and could disable towers, enable DDoS, and support encrypted criminal communication.
What happened: threat network disrupted around New York
The US Secret Service reports it has dismantled a covert network of electronic devices deployed across the tri-state New York area, used for multiple telecommunications threats. The operation uncovered more than 300 co-located SIM servers and over 100,000 SIM cards across multiple sites. These devices were capable of launching attacks on cell towers, enabling denial-of-service (DoS) attacks, or facilitating anonymous encrypted communications between threat actors and criminal enterprises.
Investigations suggest that some of the devices facilitated anonymous telephonic threats and may have been used by nation-state operatives communicating with known individuals under federal surveillance. The timing and placement of the network—in proximity to the United Nations General Assembly meeting in New York—and its sophistication prompted rapid intervention by the Advanced Threat Interdiction Unit, part of the Secret Service. Director Sean Curran emphasised: “The potential for disruption to our country’s telecommunications posed by this network of devices cannot be overstated.”

Why it’s important
This event highlights the growing vulnerability of telecommunications infrastructure. Sophisticated, covert threats are increasingly common. In high-security settings like the UN General Assembly, networks cannot be exposed. Malicious actors can exploit SIM servers and bulk card deployments. They may disrupt services, mimic identities, or hide their tracks.
The incident shows the urgent need for stronger security measures. Intelligence agencies and telecom providers must improve coordination. Threat detection and network resilience require constant upgrades. Director Curran emphasized that the Secret Service will respond swiftly to threats against protected individuals or critical infrastructure. Past attacks on providers such as Orange, Bouygues Telecom, and Colt show the potential for cascading effects. Customers, operations, and trust can all be affected.
The dismantling demonstrates proactive defense and reassures the public. Yet it also raises the bar. Telcos and governments must continuously enhance surveillance, encryption, anomaly detection, and threat intelligence. In a world dependent on seamless connectivity, securing telecom networks during global events is essential.
