How does it work?

The use of connected devices such as smart TVs and voice-activated home assistants by criminals seeking to steal data poses an emerging threat to UK consumers, according to National Trading Standards.

The organisation is therefore warning consumers about potential threats such as computer viruses, malware and data hacking.

Its findings support consumer group Which?'s recent investigation into smart home gadgets, which revealed that crooks can hack into your home network and connected appliances in just four days.

Mike Andrews of National Trading Standards said: "People often seem to think they are completely safe but there is just as much risk associated with using a smart TV as there is with using any computer connected to the internet, especially when it comes to entering your personal data.

"As criminals increasingly find new methods to target consumers, steps will need to be taken to help protect people in their homes."

How can I avoid being caught out?

It is vital to change the password on your connected devices, as generic default passwords can be easy for hackers to guess.

So set a strong and unique password, ideally one with a jumbled mix of letters, numbers and special characters.

"Some connected devices come with default passwords," Andrews said. "You should always change these passwords and look wherever possible to limit the amount of information you are sharing."

Other top tips include keeping the software or firmware updated to ensure the latest security features are installed, and ensuring all your smart devices are connected to a secure wi-fi network.

It's also worth remembering that smart devices located close to windows or behind thin doors can be more easily accessed from outside your home.
