Amazon’s Alexa started ordering people dollhouses after hearing its name on TV
The story could have stopped there, had it not ended up on a local morning show on San Diego’s CW6 News. At the end of the story, Anchor Jim Patton remarked: “I love the little girl, saying ‘Alexa ordered me a dollhouse,’” According to CW6 News, Echo owners who were watching the broadcast found that the remark triggered orders on their own devices.
Alexa’s settings can be adjusted through the device’s app, and users can either turn off voice ordering altogether, or
add a passcode to prevent accidental purchases.
Device/computer security really is the last thing on people's mind.
