The term killware is an overarching term that covers a wide variety of cyberattack types that target the real-life health of victims. While other forms of malware are usually defined by their method — think DDoS or spear phishing attacks — killware is defined by its end result, and can include any number of methods, including malware and ransomware.
Not long ago, the concept of killware was the stuff of futuristic, doomsday movie fare. The idea that hackers could breach systems related to basic public infrastructure and health services to put people’s very lives at risk seemed scary, but far-fetched. Unfortunately, that dystopian future has, at least to some degree, arrived.
