Cabinet ministers in the UK have been banned from wearing smartwatches in meetings over fears that Russian spies could hack them.
The Telegraph reports that there are fears devices such as the Apple Watch could be used as listening devices by the Russian authorities.
Mobile phones have already been banned from the Cabinet over similar fears.
The Telegraph quoted a source: “The Russians are trying to hack everything.”
Russian hackers obtained confidential emails from the Democratic National Congress ahead of the US election, according to the Obama administration, although Russia denies the accusation.
Russian spies have also allegedly gained possession of the medical files of some of the world’s most famous athletes.
The news comes as the European Commission plans to implement security standards – through a cyber security labelling system – for connected devices.
It is also expected to introduce rules that will affect how companies can access consumers’ data and sell it on to partnering firms.
A Europol report recently warned that cyber criminals are increasingly offering their services to the highest bidder, putting Europe at heightened risk of terror attacks.
