A California father said this week that a hacker infiltrated his Nest camera, commandeered the voice function and threatened to steal his baby — the latest in a string of disturbing security breaches of the devices.

Jack Newcombe wrote in the East Bay Times that a woman’s voice was broadcast from the camera when he and his wife were at work and their 18-month-old child was home with their nanny.

“The voice is laughing when it chimes in. She says we have a nice house and encourages the nanny to respond. She does not,” Newcombe wrote in the story.

Then, he said, the harmless hack took a disturbing turn.

“The voice starts to get agitated at the nanny’s lack of response and then snaps, in a very threatening voice: ‘I’m coming for the baby if you don’t answer me, bitch!’” he wrote.

Newcombe’s experience is not unique, he noted in the story.

Other Nest users across the country have reported hackers infiltrating their devices, yelling curses at owners and even using the device to raise the temperature on their thermostats.

In January, an Illinois couple said a voice spoke to their child through their Nest camera and later spewed obscenities at them.

Another couple in Milwaukee said their Nest camera played vulgar music after a hacker took it over in September.

The device is billed as a security camera designed to help homeowners and parents monitor their homes and family members from a distance.
