Security researchers have developed a technique to detect stingray modern cell site simulators
Cell site simulators, known as “stingrays,” impersonate cell towers and can capture information about any phone in its range — including in some cases calls, messages and data. Police secretly deploy stingrays hundreds of times a year across the United States, often capturing the data on innocent bystanders in the process.
Little is known about stingrays, because they are deliberately shrouded in secrecy. Developed by Harris Corp. and sold exclusively to police and law enforcement, stingrays are covered under strict nondisclosure agreements that prevent police from discussing how the technology works. But what we do know is that stingrays exploit flaws in the way that cell phones connect to 2G cell networks.
Most of those flaws are fixed in the newer, faster and more secure 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. read more
