In brief
In a proactive operation, the US Secret Service uncovered a telecommunications network resembling a possible attack mechanism just before the UN General Assembly in New York. The scheme involved over 300 SIM servers capable of sending millions of texts and disabling cellular networks. This highly organized plot reportedly linked nation-state actors with organized crime, prompting investigations following previous threats to US officials. The discovery raises serious concerns about cybersecurity and public safety amidst high-profile global gatherings.
The US Secret Service disrupted a network of telecommunications devices that could have shut down cellular networks as leaders gather for the United Nations General Assembly in New York City.
The agency said on Tuesday that last month it found more than 300 SIM servers and 100,000 SIM cards that could have been used for telecom attacks within the area encompassing parts of New York, New Jersey, and Connecticut.
This network had the power to disable cell phone towers and essentially shut down the cellular network in New York City, said special agent in charge Matt McCool.
The devices were discovered within 35 miles (56km) of the UN, where leaders are meeting this week.
The agency said officials were examining the devices, but that the well-organised and well-funded scheme involved communications between nation-state threat actors and individuals that are known to federal law enforcement.
The equipment was capable of texting the entire population of the US within 12 minutes, officials say. It could also have disabled mobile phone towers and launched distributed denial of services attacks that might have blocked emergency services communications.
McCool told US reporters that the scheme involved unidentified nation-state actors sending encrypted messages to organised crime groups, cartels, and terrorist organisations.
The devices were seized from SIM farms at abandoned apartment buildings across more than five sites. Officials did not specify the locations.
The discovery followed an investigation into anonymous telephonic threats directed at three US government officials this spring, unnamed officials told the New York Times.
One of the officials works in the Secret Service, and the other two work at the White House, according to the newspaper.
Investigators also told CBS News they found 80g of cocaine, illegal firearms, computers, and phones.
The investigation began after threats towards US government officials last spring, leading to the discovery of the devices last month.
More than 100 world leaders and delegations have gathered in Midtown Manhattan for the 80th anniversary of the UN General Assembly in New York.
