Voice assistants (e.g. Amazon Echo, Google Nest) can control everything from lights to locks, making them a potential target for hackers. If not secured, attackers could theoretically issue fake voice commands, sometimes even by playing a sound through the speaker itself.

Vlad Cristescu, Head of Cybersecurity at ZeroBounce said: "Voice assistants are always on and can even be triggered by accidental audio commands in TV commercials, risking unauthorised access to shopping, calendars, and one-to-one chats."

Leaving voice purchases unprotected or using weak network passwords puts you at a greater risk, so make sure to enable voice PINs, update firmware, and keep devices away from windows.
