An article by the US FBI warns that smart toys can contain microphones, cameras, GPS, data storage and speech recognition that can extract personal data. Toys that are connected to the internet or Bluetooth are easy to hack. For example, in Germany, the doll Cayla (made by Genesis Toys) is banned due to the danger of it being hacked. More and more devices and toys are being produced that use sensitive information about a child - name, school, and activities - to adjust the interaction and ads.
