Security researchers say they have developed a new technique to detect modern cell-site simulators.
Little is known about stingrays that exploit flaws in the way that cell phones connect to 2G cell networks, because they are deliberately shrouded in secrecy.
Most of those flaws are fixed in the 4G networks, though not all. Newer cell site simulators, called “Hailstorm” devices, take advantage of similar flaws in 4G that let police snoop on newer phones and devices. Researchers at the Electronic Frontier Foundation have discovered a new technique that can detect Hailstorm devices
