He made this observations while launching a real-time service called Overwatch to pinpoint these interceptors.
They mimic legitimate cell towers and reroute nearby cell transmissions through them.
But theyre not phone company equipment.

ESD found 17 towers initially across the US and now the figure had jumped up to 54.
Goldsmith said that the interceptors could be a listening/call-handling box.
Surprisingly ESD discovered more than a dozen interceptors near the U.S. Senate and White House.
He says NSA has enough muscle to directly tap into the phone calls instead of erecting these innocuous towers.
We want the government to be able to catch those setting up these towers, he said.
If the U.S. and friendly governments dont want the service, Goldsmith said, we wont supply it.
Goldsmith states that at least 14 foreign governments have evinced interest in the ESDs services.
The interceptor hunting is conducted with ESD-built, briefcase-sized sensing devices that the company deploys in an area.
The tech sets up a firewall that monitors connections to cell towers from ESD devices.
Goldsmith said the service doesnt monitor individual messages.
Cryptophones can also detect the IMSI catchers, but they are not designed to report back the data.
The Federal Communications Commission (FCC) has announced an investigation into the unauthorized use of IMSI catchers.
