FThis is largely due to their increasing prevalence – in Q2 2017 around 86 countries were affected by DDoS attacks, up 14 from the previous quarter. And a report by Cisco predicts that the annual number of DDoS attacks will rise to 17 million by 2020.
They’re also extremely costly – in 2012 each attack on the financial sector cost its victims an average of $17 million. This is a worrying statistic when attacks are on the rise so sharply.
DDoS attacks work by flooding their victims’ servers with traffic, overwhelming their bandwidth and causing them to work less efficiently or stop working altogether.
They generate this enormous flood of spam traffic by infecting devices such as mobile phones and computers, transforming them into ‘bots’ which can be directed to a particular server.
