On 2025-09-23, the U.S. Secret Service took down a SIM-server network in the New York tri-state area, disrupting a cyber-enabled telecommunications threat aimed at U.S. officials and national security. Investigators said they found more than 300 co-located SIM servers and 100,000 SIM cards across multiple sites near the UN General Assembly.
