U.S. Secret Service Shuts Down 300 SIM Servers and 100K SIM Cards Disabling Cell Towers

The U.S. Secret Service has dismantled a sophisticated network of electronic devices scattered across the New York tri-state area.

These devices posed an imminent threat to protective operations for senior government officials.

During a protective intelligence investigation, agents identified over 300 co-located SIM servers and 100,000 SIM cards deployed at multiple locations.

The servers and cards were assembled in clusters within a 35-mile radius of the United Nations General Assembly meeting now underway in New York City.

Discovery of the Device Network

The investigation began after the Secret Service received reports of anonymous telephonic threats directed at senior U.S. officials.

These calls appeared to originate from a vast network of SIM servers designed to conceal the true source of communication.

Further probing revealed that each server could host hundreds of SIM cards, enabling seamless rotation of numbers and identities.

This setup made it nearly impossible for standard telecom tracking methods to trace calls back to their origin. Agents discovered clusters of these servers hidden in homes, office buildings, and other nondescript sites.

Beyond facilitating anonymous threats, the network could carry out a range of telecom attacks.

Early analysis indicates the devices could disable cell phone towers, launch denial-of-service attacks on critical communications infrastructure, and support encrypted messages between nation-state threat actors and criminal enterprises.

Forensic examination of the seized hardware is ongoing, but initial data points to communications between known federal law enforcement targets and foreign operatives.

“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.

To swiftly neutralize the threat, the Secret Service’s Advanced Threat Interdiction Unit led the operation. This new division focuses on the most significant and immediate dangers to protectees.

Key partners in the takedown included the Department of Homeland Security’s Homeland Security Investigations, the Department of Justice, the Office of the Director of National Intelligence, and the New York Police Department.

State and local law enforcement agencies also offered critical technical advice and assistance. While most of the network has been disabled, the investigation remains active.

Officials are analyzing data extracted from the servers and SIM cards to uncover the identities of those involved and any further plans they may have had. The swift action underscores the Secret Service’s commitment to prevention.

By dismantling this network before the UN meeting escalated, the agency sent a clear message: imminent threats to protected individuals will be traced and stopped without delay.

As forensic teams continue their work, the agency expects to reveal more details on how the network operated and who was behind it.
