Hackers can hijack Wi-Fi Hello Barbie to spy on your children

Security researcher warns hackers could steal personal information and turn the microphone of the doll into a surveillance device

Mattel's latest Wi-Fi enabled Barbie doll can easily be hacked to turn it into a surveillance device for spying on children and listening into conversations without the owner's knowledge.

The Hello Barbie doll is billed as the world's first "interactive doll" capable of listening to a child and responding via voice, in a similar way to Apple's Siri, Google's Now and Microsoft's Cortana.
