Australians should be well aware of cyber-risk, after National Census Day in 2016 was almost sabotaged by four distributed denial-of-service (DDoS) attacks. The Australian Bureau of Statistics (ABS) was forced to take the Census site down, to protect the integrity of the data.
But if anyone was not aware, the ‘WannaCry’ ransomware attack earlier this month – believed to be the world’s biggest online extortion attempt – really should have focused minds.
The WannaCry attack struck more than 100,000 organisations in 150 countries, including British hospitals, German rail operators and Chinese universities. The UK’s National Health Service had to turn away patients after WannaCry locked up hospital computers, forcing the closure of wards and emergency rooms.
