Researchers have designed a drone that can steal data from smartphones, according to CNN.
The unmanned aircraft, called Snoopy, is equipped with sensors that detect mobile devices with their Wi-Fi settings turned on. The drone takes advantage of a feature built into smartphones and tablets, in which the devices automatically search for networks that they have connected to in the past.
The drone can impersonate networks that the user has connected to in the past, according CNN. When the phone connects, the drone intercepts all data the user sends and receives.
During an hour-long demonstration flight in London, researchers used Snoopy to obtain network names, GPS coordinates, usernames and passwords for about 150 mobile devices.
Shutting off Wi-Fi will protect users against the device. Setting devices to ask before connecting is also helpful.
Snoopy was developed by "ethical hackers" at Sensepost Research Labs, who intend to use the technology to heighten awareness of smart device vulnerabilities.
