In an opinion piece published on the South China Morning Post, Prof Kai-Lung Hui, Faculty Associate of the Institute, says organisations providing critical services must have a backup plan that does not rely on the internet in case of a crippling cyberattack.
The latest ransomware attack, WannaCry, infected more than 200,000 computers worldwide, locking out users unless they paid a ransom in bitcoins to the attackers. Some of these locked computers are used in hospitals, petrol stations, schools and power companies.
