U.S. SECRET SERVICE DISMANTLES IMMINENT TELECOMMUNICATIONS THREAT IN NEW YORK TRISTATE AREA

Summary from the TLDR InfoSec newsletter

The US Secret Service (USSS) dismantled a network of over 300 co-located SIM servers and 100,000 SIM cards positioned within 35 miles of the UN General Assembly in New York that were used to conduct telecommunications-related threats against senior US government officials. The devices were capable of performing multiple attack vectors, including disabling cell phone towers, facilitating denial of service attacks, and enabling anonymous encrypted communications between nation-state threat actors and criminal enterprises. Early forensic analysis revealed cellular communications between nation-state threat actors and individuals known to federal law enforcement, representing an imminent threat to protective operations during the high-profile international gathering.
