'Wake up baby!' The chilling words U.S. couple heard in the middle of the night from a man who had hacked their daughter's baby monitor and was WATCHING her sleep

An Ohio couple awoke in the middle of the night to the sound of a man screaming 'wake up baby!', quickly realizing a hacker had hijacked the wirless baby monitor in their daughter's room and was watching the little girl sleep.

Heather and Adam Schreck say they feel 'violated' after the midnight encounter, only worsened by the fact they have no way of working out who the online intruder was.

The Cincinnatti couple had stirred during the night, thinking they heard a voice.

Heather then checked on their 10-month-old, Emma, by looking at her cellphone , which streams the camera feed from the monitor that sits above the baby's crib.



Heather saw that the camera was moving erratically, when it is only meant to move if following the child or someone else walking about the room.

Chilling: A Cincinnati couple awoke at midnight to hear a man's voice coming from the baby monitor in the room of their daughter Emma (pictured) The Foscam IP Camera was set up above the crib, with the footage streaming to cellphone of baby Emma's mother, Heather Father Adam ran into his daughters room to check on his terrified daughter, quickly realized their baby monitor had been hacked Adam and Heather Schreck said they did not know it was possible for a baby monitor to be compromised by online intruders

'About the time I saw it moving, I also heard a voice again start screaming at my daughter,' Heather told Fox 19.



'He was screaming, ''Wake up baby. Wake up baby''. Then just screaming at her trying to wake her up.'

Adam bolted to Emma's room, and watched as the camera turned from his petrified daughter and pointed at him.

The hacker started yelling 'bad things and obscenities' at the father.

'He was screaming at me ... so I unplougged the camera,' Adam said.

They then realized the Foscam IP Camera in the room had been compromised.

'Someone had hacked in from outside,' Heather said.

'You do kind of feel violated in a way,' Adam added.

While such camera hacks have been common on computer and laptop webcams, IT experts say that internet-connected device in the household can provide an easy way for online intruders to open a cyber door directy into your home.

'It's not just that they want to get in and mess with your camera,' Dave Hatter, a solutions expert for Infinity Partners, said.

'More sophisticated hackers know they can use this as a launching off point to get into your network and potentially steal your ID or use your network to launch malicious attacks against someone else.'

Hatter's advice is to change the password on your Wi-Fi as well as the camera itself, and make them different.

Adam and Heather Schreck have upgraded the software on their baby monitor and have changed the passwords

Also, check the manufacturer's website regularly for updates you can download since the available updates may not show up directly on the device, as they do on your computer or cell phone.

The Foscam camera, for example, has a known firmware vulnerability and had released an update to correct the problem but the Schreck's were unaware of it.

While they have now added the new feature to the monitor and changed their passwords, it doesn't answer the question of who the man was or, perhaps more importantly, how many times he had hacked in.
