More than a year after it first struck, WannaCry is still one of the most damaging cyberattacks to date. It cost the global economy billions of dollars, although the impact goes far beyond the money.Although companies incurred substantial monetary damages, WannaCry is the clearest example of the physical impact a malware attack can have on critical infrastructure, such as rail systems and hospitals. This can be the case even when the attack does not target or operate on industrial control systems, medical, or Internet of Things devices. WannaCry was “standard” malware aimed at Windows machines. And yet, it affected day-to-day life by preventing employees from getting to work and patients from receiving uninterrupted medical care.
