6 Things to Know About 'Killware,' Cyber Security's Next Big Threat

Threat actors are adopting a “killware” cyber model, which launches attacks on critical infrastructure with the intent to cause harm. Alejandro Mayorkas, secretary for Homeland Security, told USA Today he is worried about killware because it has the potential to kill. Hackers breached a water system in February this year, which was considered an unsuccessful attempt to distribute contaminated water to residents of Florida. "[The] attack was not for financial gain but rather purely to do harm,” he said. https://www.beckershospitalreview.com/cybersecurity/6-things-to-know-about-killware-cybersecurity-s-next-big-threat.html
