Which technology raises privacy concerns by intercepting communications via a device that mimics a cell tower?

• A. Dark phones
• B. My Friend Cayla Doll Controversy
• C. Data mining
• D. Stingray

Answer: (D)

The concept being tested is the use of a rogue base station to intercept mobile communications. A Stingray is a device that masquerades as a legitimate cell tower, coaxing nearby phones to connect to it. Once a phone connects, the operator can capture that device’s communications—voice calls, text messages, data traffic—and often obtain location information. Because the device in range can be any phone, the interception isn’t limited to a single target; it affects all users in the area, creating broad privacy risks. This kind of surveillance raises serious concerns about who controls the data, how it’s used, and whether proper oversight or warrants are in place, since it can unintentionally sweep up a lot of personal information. Other options touch on privacy in related ways—secure or private devices, toys that listen, or data analysis—but they don’t describe the specific risk of intercepting communications by mimicking a cell tower the way a Stingray does.
