Falling victim to an online scam is bad enough, but what if someone hijacks your business's social media account, pretends to be you - and then successfully scams other people?
It happened to Sarah, who runs a floral business called Print and Petal.
She lost control of her Instagram account, and later discovered her followers had been encouraged into click on links for cryptocurrency scams - which some of them did, and lost a lot of money over.
Last year Netsafe had almost 15,000 complaints of attacks designed to either harm a computer system or its users.
Kathryn speaks with Sarah, and Alastair Miller, Principal Advisory Consultant at Aura Information Security, about the increase in such attacks, where users are vulnerable and why small business owners who rely on social media need to have a plan of what to do if they get hacked.
