On September 24, 2025, the U.S. Secret Service uncovered a large network of “SIM farms” near the United Nations, raising concerns about potential threats to telecom infrastructure. The investigation, titled “How a SIM farm like the one found near the UN threatens telecom networks,” is ongoing, with authorities dismantling multiple sites containing servers and over 100,000 active SIM cards.
- Secret Service dismantles large SIM farm network near UN
- SIM farms hold over 100,000 active SIM cards
- Potential for network overload and cellular blackouts
- SIM farms used for fraud, phishing, and scams
- Threat of surveillance and device cloning possible
- Operation indicates global vulnerability and organized crime
Special agent Matt McCool stated that the network was highly organized and possibly operated by nation-state actors from specific countries. The sites, located within 35 miles of the UN building, could have been used to send encrypted messages to criminal groups or terrorists. Although no arrests have been made, officials warn that leaving the network active could have caused widespread cellular blackouts similar to those after 9/11 or the Boston Marathon bombing. The discovery highlights how simple tools like SIM farms can threaten critical infrastructure.
- Monitor and secure telecom infrastructure against large-scale SIM farm operations.
- Enhance surveillance to detect encrypted messaging used by organized crime or terrorists.
- Regulate and track the production and distribution of SIM cards to prevent misuse.
- Develop rapid response strategies for dismantling similar networks in the future.
The investigation underscores how easily such operations can be set up remotely and remain hidden, emphasizing the need for robust cybersecurity measures. Experts warn that these farms could be used for surveillance or to disrupt communications during major events, making ongoing vigilance essential for national security and public safety.
