Backgrounder Crime doesn’t pay? Tell that to the small businesses that fall victim to cyber-attacks every year and have to fork out cash to crooks. According to a 2018 survey from the UK's Federation of Small Businesses, 5.4m of their members were attacked by cyber criminals, resulting in a loss of more than £5bn.

According to a report by insurance company Beazley, 71 per cent of ransomware attacks were aimed at SMEs, with a mean ransom demand of $116,234 (£91,493). What’s galling for these businesses is that 93 per cent of them had implemented some type of cyber protection but it all proved to be ineffective. The European Union Agency for Network and Information Security (ENISA) runs an annual survey looking at computer threats, and found email is the dominant vehicle for delivering such attacks, responsible for 92.4 per cent of malware infections.
