“Unplug your Alexa devices right now,” a voice on the other line said. “You’re being hacked.”

Apparently, one of Amazon.com’s Alexa-powered Echo devices in their house had silently sent recordings to the caller without the family’s permission, according to KIRO 7, a news station covering Seattle and western Washington state that first reported the story. The person, an employee of the husband, was in the family’s contact list.

“My husband and I would joke and say, ‘I’d bet these devices are listening to what we’re saying,’ ” a woman who identified herself only by her first name, Danielle, told KIRO. She added that the device did not tell her that it would be sending the recorded conversations.
